One of the best State Parks for fall foliage! A huge criss-cross of trails to choose from with Pikes Peak views, yellow aspen, wildlife. We’ve only done the walk-in campgrounds (there are also backpacking sites), all of them were nice and simple, clean and quiet. They provide bear boxes but we’ve never seen any here. Worth the drive from Denver. If you’re into fossils and natural history, check out the Florissant Fossil Beds National Park while you’re in the area (petrified redwoods).
