The first day was hard going; as we had set the goal of hiking up to Choquequirao on the 2nd day we needed to reach and camp at the Rosalinas bridge where the trekking route crosses the river on the 1st day and this meant 10 ½ hours on the river, a significant amount of which was portaging siphon cities. This section of river is very changeable and throughout the trip Julio commented that rapids that had previously been runnable were now impassable and former portages we could now descend safely. Unfortunately for us the first day resulted in lots of the former with promising looking lines being spoilt by siphons, undercuts or rather sticky holes! Encountering a dead body at the end of the first portage set the tone for a difficult and strenuous day. Nevertheless we arrived at the bridge with about ½ an hour of daylight left and after cooking up some soupy pasta we got to sleep knowing we had another long day tomorrow.
All in all it was a great trip with various challenges on and off the water. For anyone wanting to incorporate the trek up to Choquequirao ruins with this section of river I would recommend taking more time getting to the bridge (a day and a half maybe) hiking up in the afternoon then camping after the climb. You can then spend more time at the ruins before descending and still being able to finish the section comfortably in a day and a half.
