This was a fun excursion because it offered several activities: horseback riding, hiking, spelunking. I'll begin by admitting that I am 61 years old and overweight although I have been working out and lifting weights. I was one of the two older participants of our group. Some caveats, however...footwear is an issue. They want you to wear rubber boots for all activities. Be sure to bring socks. I chose to wear my tennis shoes and would not have been able to make the hike without them as the climb is up mountainside with no real path and large, pointed boulders. Once inside the cave, the ground is VERY SLIPPERY with mud and sharp rocks. I fell twice ( I was the only one in the group to fall). The guides were helpful and tried to be careful. One other thing: the jumpsuit that I wore began to smell strongly of BODY ODOR shorthly into the hike. I was so embarrassed until I realized that the smell was embedded in the material from multitudes of past wearers. Just be aware of the possible dangers: my bruises are just now starting to fade a week later.
