Fall brings spectacular scenery and the annual elk mating season (rut), where huge bull elk battle for their harems with eerie, echoing bugles across wide valleys. Cooler fall temperatures create photo opportunities in Yellowstone Park, with the fog turning to steam over the rivers and geysers. It’s a great time for mountain biking, road cycling, hiking, and photography in Yellowstone and the surrounding national forests. Spawning runs of big, battling brown and rainbow trout migrate from Hebgen Lake up the area rivers. Being one of the top fall fishing destinations just adds to the reason we are the heart of fly fishing in the Rockies. Even a rainy fall day can be fun with a visit to the Grizzly & Wolf Discovery Center. Meet the two wolf packs and resident grizzly bears, observe the raptors, talk to a naturalist, and check out the Keeper Kids program. Next door, the movie Yellowstone plays daily at the Yellowstone Giant Screen with a six-story-high movie screen. Late fall features the annual West Yellowstone Old Faithful Cycle Tour.
