The hike up to la junta is long. If it rained the night before, longer! It took us 6 hours to trek through the foot deep mud, but was well worth it. The views form the top definitely rival those of Yosimite Park in the U.S. The refugio is great and the food is tasty and healthy. Definitely worth the trek up! Bring water shoes to cross the river and supplies to stay the night. It is definitely too much to walk up and back in one day.
