Yellowstone is a huge national park, so it is to your advantage to be centrally located. Canyon campgrounds give you easy access to all parts of the park without having to change campsites. It is a large campground, with clean and handy laundry and shower facilities. The sites are wooded and spread across several loops. The highly informative visitor's center is in a complex of shops, restaurants, and post office. Everything you need is right there, and the employees of the park are helpful and friendly. From Canyon, you have easy access to both Hayden and Lamar Valleys, which are prime wildlife viewing areas. You can also easily get to the thermal areas, as well as the stunningly beautiful Grand Canyon of the Yellowstone waterfalls. There are countless hikes, long and short, throughout the park. Canyon is my go-to campground whenever I am at Yellowstone!
