First of all I want to encourage everyone to read the negative reviews because there is a definite pattern of Josh being late or not showing up at all. In fact a couple that was there waiting with me said that Josh was a half hour late for another hike they had done with him. There’s also a pattern in their responses. Read them. Here’s my experience with Yellowstone Hiking Guides. I booked the Lamar Valley hike months in advance and had been looking forward to it. I received a confirmation email and was reminded to be at the trailhead at 8:00am. I had about an hour and a half drive so I left a little before 6:30am. I got to the trailhead a little early and waited. As time went by I began talking with the other hikers. At about 8:30 Josh had not shown up yet and one of the hikers said that he sent an email at 6:30 saying he would be a late and would arrive by 8:30. So, if anyone has been to any national park they know there is no cell reception. If anyone has been to Yellowstone they know it is a very long drive to get anywhere. At 9:00 Josh had still not shown up. I was done waiting and left. The thing I believe Josh forgets is that we tourists travel from all around the world to come to this magical place and for many of us it is a once in a lifetime experience. To treat us with such disrespect and unprofessional behavior is absolutely disgusting. Yes, Josh sent an email but also didn’t live up to it. Yes, I received a refund. Yes, Josh offered a free hike to make up for it. My question to him was that he already ruined one day of my vacation, why should I trust him to not ruin another one. So, buyer beware and do your research. I believe Josh means well but is not responsible enough to trust with a full day of your vacation.
