My son and I booked a two day private tour with Yellowstone Safari in August. We did the Best of Yellowstone and the Wildlife Safari. I did a lot of research before this trip, and I chose Yellowstone Safari because of their excellent reviews. I am glad that I did because our trip was PERFECT! We met our guide Zak bright and early in our hotel lobby. He was punctual, organized, easygoing, fun, and so knowledgeable about the history, geology, and wildlife. He took care of all of the details so that we could relax and soak in all of the beauty that Yellowstone has to offer. On our first day, we saw Grand Prismatic Spring, Old Faithful, Yellowstone Lake, West Thumb Basin, Hayden Valley, and Grand Canyon of Yellowstone. On the second day, we toured Mammoth Hot Springs and Lamar Valley. We saw two bald eagles, bison, a wolf, mountain goats, baby osprey in a nest, mule deer, elk, prong horn, and a coyote swimming across the river. We also took a hike up to Trout Lake. The view was just breath taking. Zak had lunch ready for us each day and found some lovely picnic spots. We were unaware that he was taking pictures and videos of us, and we were surprised when we saw them when he dropped us off. These are memories that will last a lifetime. I highly recommend Yellowstone Safari and their fabulous guides. Come to Yellowstone and Zak will teach you about the wonders of Yellowstone. I am so happy that my son and I got to have this experience with Yellowstone Safari.
