For our August visit to Yellowstone, we wanted to get away from the crowd, enjoy wilderness and see a few animals. We spent two perfect days with our guide Lynn. Without him, we would not have gotten up at 6:00 and seen wolves, we would not have even known where to go and see them, we would not have understood the dynamics of the different wolf packs, we would not have dared hiking by ourselves in the backcountry for fear of bears (possibly unjustifiably, but still), we would not have discovered this incredibly beautiful creek. In brief, I would have been driving all day long and we would not have made the most out of our stay. Sure, we did not see any bears. Lynn tried really hard to find some but none showed up! Lynn is very knowledgeable and enthousiastic. Our stay in Yellowstone has been a real success. Swiss family of six.
