My fiancee and I did the Lonestar Geyser hike in early July and had an excellent experience! A few weeks prior to the trip, Josh reached out to us to tell us a guide had been injured and he needed to switch us to a different hike, but when we could not make that hike he was able to accommodate us on a different day. We appreciated this flexibility and willingness to make both his and our schedules work! The hike we ended up going on was great and our guide, Zach, was excellent, we even learned about local plant and animal life in the park.
