In the summer of 2021 I hiked the Teton Crest Trail with friends. Set in Grand Teton National Park, it is one of the most beautiful hikes in the country. It varies in length depending on the trailhead you use, but the basic TCT is about 40 miles with ~9000 ft of elevation gain. You can easily customize the hike length by adding side hikes; we ended up hiking 53 miles and ~11,000 ft.

It can be hard to get permits online when they become available. However I just showed up the day before I wanted to start hiking and got walk up permits. There are walk up permits available everyday. Just go in with several itineraries and the rangers are happy to work with you. Also, the Teton Crest Trail goes in and out of National Forest where you don’t need permits to camp making it relatively easy to put a route together. I had booked a campsite at Colter Bay in the National Park for the first two nights so we had a place to stay while we prepared for an early morning queue at the ranger station to snag permits. However, we got permits the first afternoon we arrived and were able to start hiking the next day.
