I did this hike last week with two friends. We booked a tour in San Pedro for 100Q each which included car transport (not tuk tuk, woohoo!) to and from San Pedro, our entrance fee, and of course the guide. The road to and from San Pedro is a bit nauseating, but thats okay.
We hiked from the pueblo above San Pablo (Santa Catarina I think?) where we met our local guide, Nicolas. He was a doll and taught us a lot of stuff about the local cultures and the story of the Nose. The hike up is a bit tough only cuz of altitude, and we left around 10am walking so it was quite hot and sunny. It was a picture perfect clear day however, and we could see all the way to the Pacific Ocean on one side, and 7 volcanoes on the other- so so so cool.
Highly recommend this hike, especially if the San Pedro volcano seems too much. It is beautiful to get above the Lake and experience the perspective.
