Family friendly, cannot wait to revisit!! - Wow! This tour was fantastic! Our tour guide Gerry was extremely knowledgeable and had a great sense of humor. This activity is very affordable at around $10 per ticket and took a little over one hour. The instructions in the ticket email were extremely detailed on where to meet. The "caves" get cool, so bring a jacket! Tour size was intimate and we completed the tour easily with my son in a hiking backpack and my disabled father. This is a great tour rich with history and I cannot recommend it enough!

An interesting experience - A very interesting cave tour in the Sun Mountain, partly due to the fantastic and humorous female guide who captivated all ages in the group through her informative stories, voice and humor. There is much to see, it is getting colder and colder and the mixed company remained attentive partly because of the empathy of the guide.
