PHOTO 2: The second photo is a nice interpretive sign about 100 feet up the trailhead (that starts out as a road). Finding the start is easy--you just begin the hike from the snack shop and breakfast area in the camp. The camp is sweet, they have cabins to rent WITH HOT WATER! and bunk beds. It is also a great spot to acclimatize as the cabins are high in the mountains. They are a bit pricey though (maybe $65 a night) and I would recommend reserving one a day in advance. When we were there the Mexican Boxing team was had the place about 90% booked. They use the area to train due to the altitude.
