State park · Custer State Park · South Dakota
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.
| Hookups | Mixed: none or electric |
|---|---|
| Max RV length | RVs over 27 ft unsuitable |
| Cost | $16–$34 |
| Fees | Approach via SD 89, not Needles Highway. |
| Reservations | South Dakota GFP; one year ahead |

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.

The campground is not suitable for RVs or trailers longer than 27 feet. Even with a smaller rig, verify your exact site dimensions in the reservation system.
Approach from Custer on SD-89. Do not route through the Needles Highway; the Needles Eye tunnel is only 8 feet wide and 9 feet 9 inches high and most RVs will not fit.
