This tour was fantastic! Tyler handled all the arrangements and we were able to have our guide meet us at a place that was convenient and fit with our dinner plans that evening.
Our guide, Chris, was extremely knowledgeable and was able to identify all the animals and plants we encountered. We started our day with a hike to see Fairy Falls and the Imperial Geyser - a relatively flat 7 mile round trip including an overlook of the Grand Prismatic Spring.
Part of the tour included lunch, which Chris provided. Sandwiches, 4 types of cheese, crackers, fruit, desserts - a REALLY good picnic lunch!
As a bonus, totally by coincidence, we got back to Old Faithful right before it erupted!
I liked that we could customize our trip - it was not canned. I told Tyler what we were after and he made some really good suggestions to build out our day. It was nice to have someone else driving us around the Park on our first full day there (TIP: if you do this tour, do it on your first full day at Yellowstone. Our guide was able to make some very good suggestions regarding things we could see on the following days, based on what we had already seen and what he knew we liked to do.).
All in all a great experience!
