Sylvan Lake Campground

Sylvan Lake Campground is the high-country campground of Custer State Park in South Dakota's Black Hills, and it is the park's scenic choice, sitting near the lake and the Needles. Our Custer guide covers it briefly: 39 sites with $34 electric RV sites and $16 tent-only sites, and it suits campers with rigs under 27 feet who want the prettiest setting in the park and are willing to compete for it, because it is the hardest Custer campground to book for summer dates.

Why RVers stay here

Sylvan Lake Campground is the high-country campground of Custer State Park in South Dakota's Black Hills, and it is the park's scenic choice, sitting near the lake and the Needles. Our Custer guide covers it briefly: 39 sites with $34 electric RV sites and $16 tent-only sites, and it suits campers with rigs under 27 feet who want the prettiest setting in the park and are willing to compete for it, because it is the hardest Custer campground to book for summer dates.

The practical picture: electric only, no sewer at the pad, with shared water and dump station where listed, plus the $25 seven-day park vehicle license and a $10 online fee for nonresidents. Reservations open one year before arrival at 6 a.m. Mountain. The hard rule is length: the campground is not suitable for RVs or trailers longer than 27 feet, and large rigs and trailers must approach from Custer on SD-89, never via the Needles Highway, whose Needles Eye tunnel is 8 feet wide and 9 feet 9 inches high. The trade-off is that the best-looking campground in Custer is also the most restrictive.
