Well known as the source of the Amazon, the mighty Apurimac makes its boldest statement in the bowels of the Acombamba Abyss. It is here that the river makes its final plunge to the jungles below. Starting in the highlands of Arequipa the river flows in a northwest direction forming the borders of the department of Cuzco to the east and both Apurimac and Ayacucho to the west. Below Puente Cunyac and the popular 4-day stretch of commercial whitewater, the Apurimac begins a thundering descent into the chasm formed below the snow capped peaks of Salcantay and Quishar which form the backbone of the Cordillera Vilcabamba.
The run features several days of relentless, big, pushy whitewater in a spectacular vertical walled canyon. Hot springs and the ruins of Choq’equirao are several bonuses to this spectacular whitewater odyssey. The river is runnable in the dry season from July to the end of October.
The put in for the Abyss is the normal take out for the commercial Apurimac stretch at Puente Cunyac, which lies along the Cuzco-Abancay highway. At an elevation of 1850 meters the river corridor here is dry and arid as it lies in a rain shadow of the Andes. The information below was compiled from a five day kayak only trip that began on October 26, 2001. The flow of the river at the put in was estimated at 2000 CFS .
The put in is at either Puente Cunyac (KM 0) or 12 km downstream at a hot springs called Banos Cconoc. A day by day summary is as follows:
Day 1 12 KM of class 2 boating to the Banos Cconoc (2-3 hours) and 20 additional KM to entrance of river on right at beginning of horseshoe canyon at 1680 meters.
Day 2 7.5 KM of progressively more difficult boating involving two portages. Finish elevation 1580 meters.
Day 3 5 KM with huge drops containing house sized boulders. Several portages and many rapids run down small channels rather than out in the meat. Finish at 1460 meters.
Day 4 21.5 KM of boating to 1235 meters with some huge rapids and at least one portage. Passed the Quebrada Arma the walls of the river become completely vertical with several unportagable and almost unscoutable drops.
Day 5 25 KM of big water boating to Puente Pasajes which lies just beyond confluence with Rio Pachachaca. From here one can hitch a ride in a truck to Andahuylas (12 hours away) but beware there is little to no traffic on this road. At Pasajes the river is over 4000 CFS with the added tributaries.
From this point one can continue 1-1/2 days downstream for an additional 70 km of boating to the village of Villa Virgen where a motorized river boat (Pecky-Pecky) can be hired for the 50 KM (4 hour ride) to jungle town of San Francisco which lies at 700 meters above sea level. In San Francisco buses can be found for 12 hour ride to Ayacucho. Although we elected not to run this last stretch it has been described to me as containing Grand Canyon style rapids with surrounding jungle vegetation. The sounds of birds and monkeys echo through the canyon. Long pools are followed by substantial drops . People and villages start coming into view. If you run this lower stretch be aware of the dangers of Malaria and Dengue which are found at this sub 1000 meter climatic zone.
Note: Beware of the onset of rains starting in the month of October. On our trip the volume of the river nearly doubled overnight with the onset of rains that changed the color of the river to a terrifying dark brown.

I’ll be making this run August 2012. Any updates I should know about? I heard the Pasaje bridge is out now. I’m going for a land-based scout trip August 2011 and I’m looing for pertinent info. Thanks
Some friends are on the river now..I will let you know what they say is happening
Great! I’ll look forward to the report. –West
These guys just got off river at Pasajes..Paid to have a car come meet them there. not a bad idea. I waited a day and got a ride on a truck that lost brakes and crashed. I had blood coming out of ears and a concussion but still took 2 more days to get to the hospital in Cuzco..If you do plan a car make sure you get there on time..WE got unexpected 20 hours of heavy rain that changed the river overnight into raging brown terror zone. We debated hiking out but pushed on. I think we ran some chicken lines that normally never have water and at other times were able to run the meat of what is normally a portage or sneak.

Yo! We took out at puente pasajes, and had a car meet us there for about 250 dollars. It drove us back to cusco, took 12 hours. there is traffic, but the locals say the trucks go by early morning, and it is mostly drugs trafficing trucks… heading to Santa Teresa now for two more days of kayaking, then off I go to work in the Caribbean for three weeks. 🙂
Are you the first gal to run the Acobamba Abyss? I’m planning an expedition for next August and would really appreciate a detailed report and any pictures or video you have of this trip. Thanks
West a bit more info on the bridge in abyss
I saw there were questions regarding Puente Paisaje on the sight. As of now there is a bus everyday at six A.M. headed for Andahuaylas. Take care. Nate
