I had planned on only going to the lower peak. I bushwhacked toward the saddle, starting from a third of the way up the normal trial. It was very thick brush and slow moving. I eventually got the the saddle and the lower peak. I didn't want to return though the brush, so I tried going on the steep hill up and over the forest. I ended up climbing high enough that it made more sense to just go to the top and take the normal trail down. I ended up climbing Ahuaca 4 more times in the next week.
Had the day off, so I went to see how close I could get from the upper peak to the lower via the saddle. Walked down the upper and got about level with the lower peak, but I couldn't continue because the rock was too steep.
