The majority of the park’s annual visitors come during summer high season, when temperatures are in the 70s and 80s and afternoons are punctuated by thunderclouds that only add to the dramatic views. Grand Teton National Park offers a smorgasbord of adventure—from biking and boating/floating, to fishing and bird-watching, to hiking and climbing. And this is a park that you will want to experience from the 200 miles of trails within its boundaries, well away from the main roads and parking lots. During spring and summer, birds, wildflowers, and wildlife abound (including elk, bald eagles, and, yes, bears), making this is a great place to hone your own photography skills.
During the fall shoulder season, visitors are treated to blazing yellow and orange leaves as the deciduous trees start to shed. Fall is breeding season for elk and moose, so these animals are especially active.
Winter is low season because of the frequent snowstorms and subzero temperatures. But the jagged, snow-covered peaks are at their most spectacular, and you’ll likely have the snowshoe and cross-country ski trails practically to yourself.
