Backcountry campsite 2S1 (Lower Slough Creek) is located 4. 3 miles along the Slough Creek Trail plus an additional 0. 6 miles off-trail, making it accessible for backpackers seeking a remote fishing and camping experience in Yellowstone's Tower area.

The site accommodates up to 8 people with 12 stock animals, features a bear-proof food locker and fire ring, and offers multiple flat tent locations with views of the surrounding valley.

A backcountry permit is required (limited to 3 nights June 15-September 15), and the site is popular with anglers accessing the clear meadow waters of Slough Creek.
