The new river guidebook just went on sale! It covers El Salvador, Honduras, and Nicaragua, and is the last installment of a trilogy covering northern Central America. It covers 205 runs with something for every paddler, and includes river descriptions, maps, photos, and side stories. Like the first two books, it’s been a years-long labor of love, and a heck of a lot of fun. It’s available now on Amazon. For more details see the MWW web site. Here are the covers of the three books:

About the author: Greg Schwendinger has been exploring the rivers of Mexico and Central America since 1999. He has survived more than 350 first descents, more than half of them solo.

The Río Cahabón, Guatemala’s most important rafting river, is under immediate threat. And I’ve met the leaders who have a chance to save it. But they need your help.

(this letter is on the web here. to see this letter in Spanish click here)

My name is Greg Schwendinger. I am a 13-year resident of Guatemala, and the author of the “Mayan Whitewater Guatemala” guidebook. I have written sporadically about the threat that hydroelectric dams pose for Guatemala’s wild rivers in the past, but this is the first time I have committed myself to do something about it. If you care about wild rivers as I do, you will quickly understand why.

The Río Cahabón offers a 3-day rafting trip through the eastern Guatemalan lowlands and home of indigenous Q’eqchi Maya people. In 1999 Paddler magazine named it one of the top 12 jungle river trips in the world. It offers a combination of turquoise-colored water, exciting rapids, and true multi-day adventure that is unique in Central America. And a dam called Oxec II is going up right in the middle of it, stealing from the local residents part of their identity, and robbing future generations of a natural and cultural experience that is irreplaceable.

While hydroelectricity has its place, I believe all would agree that each project deserves a rigorous scientific study, public debate, and consultation of the populations directly affected. The Oxec II project has none of that. And its direct and indirect environmental and social effects will be significant.

Fighting such a the dam is a huge challenge in Guatemala. In many cases, the government control that the oligarchy has (this project’s owners included) is almost unassailable. But this project is angering thousands of local villagers, and the human rights issues (non-consultation of the local people), among other legal issues such as the land acquisition, is one that the courts have shown a willingness to consider.

There are several groups lining up against the dam. The central one is an association of 100 local communities led by a directorate of 10 local organizers. The communities are impoverished but the leaders have experience fighting such projects (they have halted a smaller one on the nearby Río Lanquín) and are strongly committed to the cause. The leaders promote peaceful action, since they have seen in other parts of Guatemala that more forceful protest often backfires in Guatemala. An important group accompanying them is Colectivo Madre Selva (, a non-profit that supports such communities with legal support, and by the way also supports community-run mini-hydroelectric projects. Madre Selva has a strong community and human rights orientation, and in my conversations with several of their people I have found them exceptionally dedicated and knowledgeable.

While this fight is on principle, money is also needed. Without it, the resistance is severely handicapped and a long-term and non-violent solution is doomed. As explained in the attached proposal from Madre Selva, about $20,000 is needed not only for the legal costs but for community education and political activities. Madre Selva operates on a bare-bones budget (mostly grants from European Union governments and NGOs targeted for specific projects), and the communities are some of the poorest in Guatemala. Despite having trouble providing for the families, the community members are willing to attend meetings, travel, and protest to save their river, but it is unrealistic to expect them to put up a prolonged fight without outside resources. And according to Madre Selva (and me) their involvement is absolutely critical. All money raised will be administered by Madre Selva in direct support of the communities and their activities.

The first public salvo by the communities happened on December 11, 2015, when one member from each of the 100 communities traveled to Guatemala City to accompany a press conference, a meeting with the Human Rights Commissioner and representatives of the license-granting Energy and Mines Ministry, and also a meeting with the powerful Commission Against Corruption and Impunity. I personally supported this action, providing a $2.80 lunch each of to the travelers. One of the next important steps will be to conduct an area-wide referendum with the assistance of the new town council (the old mayor was voted out exactly because of his support for the project) and preparations are already underway.

Below I have links to more background information for you to chew on. I urge each of you to consider making a generous donation to the Save the Río Cahabón fund. A small donation ( $1,000) helps a lot. Rarely will you have an opportunity to make your money go so far to directly support an important river issue. As explained below, in the U.S. (and worldwide) you can make a donation via Sierra Rios (, and in Guatemala (and worldwide) you can make a bank transfer to Madre Selva’s account.

(Be under no illusions: this will be a drawn-out fight with no guarantee of success. Additional ill-advised projects are planned on the Cahabón, which is why it is critical to make a stand now and find a way to hold these projects up to public scrutiny. Whether we win or lose this battle, your money will raise local and international awareness and encourage those on the ground to keep fighting.)

Big news this month: the Guatemala guidebook is finished! “Mayan Whitewater Guatemala” is the first and complete guide to the rivers and creeks of Guatemala. It covers 226 runs on 126 rivers including the steep creeks, the dark caves, the big water rafting runs, and everything in between.

The book is available on for $35. For bulk orders, contact me directly at

Where is Guatemala? Just south of Mexico, so a quick flight from USA! If you are an adventurous kayaker, you should put Guatemala on your bucket list.

About the author: Greg Schwendinger has spent 13 years exploring the rivers of northern Central America. He has survived more than 250 first descents, more than half of them solo. He is also the co-author (with Rocky Contos).

Think you know South American paddling? Maybe you’ve been to Chile? Ecuador? Well, the Andes offer much more. A new playground is opening up: northern Peru. It’s got big clean water, multi-days, and lots of creeks.

James “Rocky” Contos of SierraRios has done more in the past couple years to open up Peru to paddlers than anyone since perhaps the Canoandes expedition of 1979. Besides discovering the true source of the Amazon (see below**) he has been running commercial trips, two to four weeks long, on the Amazon’s biggest tributary, the Río Marañon. This is an amazing Grand-Canyon style trip. The Río Marañon cuts a course north almost all the way to the Ecuador border before curving east to feed the Amazon basin.

In early February, a group was finishing off a Marañon trip and Rocky invited some of the better kayakers to join him in exploring some of the bigger tributaries of the Marañon, and Kurt Casey of and myself hopped onboard. There were nine of us (see below for the names*) who met in Bagua which was our just-outside-the-jungle base for the first river we wanted to explore, the Río Chinchipe. Some parts of this big river (> 10,000 cfs at the confluence) have been run, but as far as we knew no one had attempted it from as high as Rocky had planned…from inside Ecuador! We drove to the border the first day and negotiated our return passport stamps with the officials before venturing into Ecuador the next day. Here the roads became dirt but were passable by our minivan until mid-afternoon until we were blocked by a landslide just outside Palanda. There was nothing to do but leave the boats with a farmer, hoof it to Palanda, and hope the road would open overnight and we could retrieve our boats in the morning. Which did in fact happen. There were several large tributaries to choose from as starting points (future explorers take note) but we opted for what seemed a likely first descent on the Chinchipe’s main tributary, the Río Numbala, putting in at an elevation of 940 m, below a > 100 ft/mi section (next time), about 8 km from Palanda. Rocky estimated a four-day trip, which panned out.

Jesse searching for a put in

The Numbala was already running > 2000 cfs at that point with busy rapids full of waves and holes. Our goal that day was to meet our raft coming down on the Río Canchis border run, which seemed pretty doubtful considering the 48 km distance, but the jungly solid class IV river turned out to be all read-n-run and despite some flips in the holes there was nothing much to slow us down and we found the rafters at camp shortly below the confluence. We were all beaming from an exciting run and looking forward to more. The next three days the rapids were more spaced out but there was plenty of excitement. The big feature on the second day was the IV+ Naranja rapid, a fearsome stairstep rapid near the road. Rocky rowed the raft, and we all had clean runs, on chicken lines or otherwise. On the morning of the third day we scouting another big rapid which turned out to be pretty clean and offered a fun surf wave at the bottom. By the fourth day things had calmed down quite a bit and we made to the Marañon and the last big wave train rapid shortly after mid-day. Camps were plentiful, pretty, and largely bug-free which was a bonus.

After helping Rocky ship back the expedition gear to Huaraz, and bidding goodbye to our rafter Ira, local guide Luciano, and kakayers Jesse and Scott, the next mission was the Huancabamba, higher up and a bit to the west. This was to be kayak self-support, again four days, so we dropped off our luggage at Jaen (nearby and civilized and our base for the rest of our stay), and drove eight hours into the night and up the mountain to the town. The Huancabamba area was more arid, though it drizzled on us the first day. This was another enjoyable trip with varied desert-like scenery and changing landscape colors. Flow started at a measly 200 cfs but finished well over 2000 cfs. The difficulty was mostly class III with the exception of fun class IV creeky canyon sections the first and second day, and some big water class IVs the last days. The third day we had to paddle across a reservoir created by a dam (diverting water to the Pacific side through a tunnel!) but even that turned into a nice experience as the dam workers helped us portage our stuff to the outlet and even gave us lunch. In general we found the Peruvians very curious about our adventures and proud of their natural resources.

Kurt and Josh on the lower Huancabamba

On the fourth day the consummate explorer Rocky paddled the Huancbamba all the way to the hot springs at the Marañon while the rest of us opted to take-out near Jaen. After the Huancabamba it was Kurt and Lorenzo’s turns to head back home, which left Rocky, Josh, and I to continue playing. Our next missions were on rivers that we found while driving or running the first two, all of which turned out to be stellar and turned the difficulty up a notch. First was the Río Chunchuca, 30 km long starting at Chunchuquillo, running at over 2500 cfs with some short sections tilted to 100 ft/mi. The road up is along the river, which was wall-to-wall waves and holes, but it was these steeper sections that gave us some pause. After an hour we got to the first long steep rapid which precipitated some bouldery and brushy portaging. To save time we portaged the next steep parts wholesale, climbing up to some fields and cutting across. We probably portaged a full kilometer all together. On most of the river we moved fast however, and the stormy sea rapids were a hoot. Josh and Rocky christened it the NF Payette of Peru.

the runnable run-out

At this point Josh had to depart so it was left to just Rocky and me to tackle what turned out to the be the toughest river of the trip: the Chirinos. This big clean river comes into the Chinchipe river-left, which meant a car ferry at Puerto Ciruelo (soon to have a bridge) and then 3 more hours of dirt road. The view of the downstream V-shaped canyon was daunting, especially with 4500 cfs of tea-colored water flowing by with an average gradient of 60 ft/mi, but we put on at 1pm anyway. Just as we congratulated ourselves at passing one rapid, another steeper and longer one would appear. We started running the chicken lines along the shore. We made good progress until about 4:00pm when a class V sequence appeared with a cliff on the left and a fresh rockslide on the right. After some scouting we portaged the beast. Soon after we encountered another steep class V rapid with another grunt of a portage. Things started to ease up a bit but we were still going slow down some chicken lines, then over easier II/III at dusk. Eventually darkness took over and we bivouaced in small caves (I displaced a scorpion in mine) for the night. The next morning it was one big but boat scoutable rapid and then straightforward down to the confluence. We were just 1 km away the night before.

good stuff on the Chirinos

too good

The road back to Jaen passed by another interesting river that was also running full, the Tabaconas, so we decided to make the best of the situation and hopped on that. The Tabaconas was another with good road scouting and turned out to be one big bouncy toboggan ride for about 20 km before getting flatter for the last few kms. Great fun, and raftable, though it would take a little skill to stay out of the trees.

All in all I just can’t say enough about the river running potential in this almost unknown part of Peru. We checked out a couple smaller creeks also that didn’t have enough water, but there are plenty more in the area to explore. Come check it out, maybe in conjunction with a raft-supported Marañon trip, or on your own. SierraRios has gear for rent which is helpful the way airlines are these days.

Some of these rivers are already written up on, another good resource for Peru beta.

* Paddlers participating included Kurt Casey, Josh Fischer, Scott McBride, Lorenzo Bergamin, Jesse Mogler, Rocky Contos, Greg Schwendinger, rafter Ira Estin, and local guide Luciano Troyes from Jaen who runs the nearby Gotas de Agua nature reserve.

Announcing the Mayan Whitewater: Chiapas & Belize guidebook!

The authors, Greg Schwendinger and James “Rocky” Contos, have spent over 10 years each, exploring the rivers of Mexico and Central America. They bring you all the runs in Chiapas and Belize, from the famous Agua Azul Falls to the jaw-dropping Santo Domingo canyons to the multi-day Usumacinta raft trip, and all the rivers and creeks in between. Maps, detailed descriptions, travel information, photos, all included. Plus stories of history and adventure from the early and later explorers.

This is a guidebook that opens up southeast Mexico and Belize like never before. To order, visit

…in Guatemala, in the cycle of the (long-count) Mayan calendar ended Dec 21, that is.

4 kayakers from Rios Guatemala and set off to explore the lower Río Machaquilá in the jungly Petén region of Guatemala. It was more of a scenic/research trip than a hard-core whitewater trip, but the video is fun and shows what it’s like to do a multi-day expedition in Guatemala.

A week ago I found myself high up in the drainage of the Río Madre Vieja. The lower Madre Vieja has been known for a few years now as the “fastest drop around”, dropping continuously at 140 ft/mi but hardly needing a scout. I’ve dropped the 1600 feet in 2.5 hours without breaking a sweat. Anyway, I hadn’t gotten up higher before due to 1. lack of car access, 2. lack of water, and 3. the intimidating gradient (200+ ft/mi) and narrow canyons up there.

Just 2 months ago a friend of mine, Axel Alburez, went hiking up there, looking for a canyoning-camp route. They estimated 4 hours to hike 4 km of the river. When they hadn’t shown up by noon the 2nd day several of us starting making plans to go in and the look for him the 3rd day. As it turned out they found their way out just before dark the 2nd day. They reported a deep narrow canyon with many cliffed-in waterfalls that forced them to climb up and down constantly. However, at their exit point, 3 km above the known kayak put-in and only 1 hour from a road, the canyon appeared to be mellowing a bit and he guessed it to be more runnable. Thus was formed the challenge in my mind.

On July 4th independence was gained. We arrived at the trailhead under a cloudy sky. A couple local kids volunteered to be our trail guides, and in 45 minutes we were at the river with a nice low first-descent flow, about 250 cfs. The first 10 minutes was fun boogie-water, then at the first steeper bit I got out of my boat. While scouting, I turned around to see my boat running the rapid without me! I hate it when I’m stupid. I was almost able to grab it as it went by me, then I was off and boulder-hopping to keep up with it. As the rapid curved I looked up to see the river dropping between two cliffs. I was thinking that if I didn’t stop the boat now I may never see it again. Luckily right then it eddied-out just long enough for me to grab it. After catching my breath it was time to scout the drop into the chasm. Oh, did I mention I was alone?
As it turned out I was looking at the entrance of the first of four mini-canyons on this run. This first one was the most spooky, with a good-sized cliffin-in drop at both the entrance (a 12 ft-slide) and exit (16 ft-slide). Luckily both drops were good to go, though it took a bit of strenous climbing to verify. In fact the run is fun as heck, and an incredible experience visually. Definitely one of the best runs on the Pacific side of Guatemala. With all the scouting it took me 2 hours to go only 3 km, but who’s in a hurry?
There’s still plenty left to discover in this part of the world, folks!

Hi everyone,

Anyone who has ever thought of paddling in Chiapas, Mexico, either in person or virtually, should check out the Chiapas river guide on All the known runs are now described, and charted on the map. Check it out! Some fantastic whitewater awaits!

March saw a return to the amazing Candelaria Caves in Guatemala. Have you ever paddled inside a cave for hours? This is a beautiful and unique place to be sure. Along this time was Marco from Italy.



Very few people, much less kayakers, have seen all the caves we get to.
