From Bozeman, we made our way towards Breckenridge CO via Yellowstone and Grand Teton. We followed the Gallatin out of Bozeman and made our way into Yellowstone through the west entrance.
As we made our way into Yellowstone, we realized that it was Labor Day weekend, which meant it was going to be especially busy in the already popular park. We didn't have much trouble, but it was a notably different experience queueing up for parking and having to say 'excuse me' countless times on crowded boardwalks. You definitely get a Walt-Disney World vibe when a tour bus rolls up to Grand Prismatic Springs and starts unloading excited tourists wielding selfie sticks and sporting Yellowstone sweatshirts.
Travelers come from all over the globe for good reason. Yellowstone brims with natural wonders. The high altitude, arid climate, and pervasive volcanic activity create a unique kaleidoscopic landscape. Thanks to impressive work by the parks service, much of this incredible landscape is incredibly accessible. The park is structured to accommodate visitors driving to each major scenic location on the loop road, and many key viewing spots are wheelchair accessible. This does mean that in peak season, you're not going to have the place to yourself. Hike just a few miles though, and the crowds thin notably. If you're willing to walk, or willing to be cold (off-season, early AM) you can see major attractions without the crowds, but we were on a time crunch, so we took one small hike and enjoyed the people watching at the iconic sites.
