If I could, I would give it no stars. My husband and I booked a tour for 9/18/2021 which was supposed to start at 8:00 am. We got up early as we had to drive from Gardiner, MT and wanted to make sure we weren’t late. There were 7 other people scheduled for the hike and we all met at the designated place. Well, after waiting until 8:30 am with no guide and several calls to the number given to contact them to no avail, we all decided he/she was a no-show. We all went on with our day. We got an email from Trip Advisor the next day saying we would get a refund, which we did, but no apologies, excuses….nothing from them or Yellowstone Hiking Guides. Very disappointed and would never recommend them.
