Legion Lake Trail

Why go

This is the park’s mellow, scenic lap around Legion Lake—an easy loop with constant water views and classic Black Hills granite and pine backdrop. It’s the definition of low effort, high reward, and a great add-on to a beach or picnic stop.

Trail overview

The loop is about 1 mile total around the lake, essentially flat with only gentle undulations. Expect a well-trodden dirt path with a few rocky or rooty bits. It’s easy for most hikers and kids, but not fully ADA-accessible in all sections. Plan 20–40 minutes at a relaxed pace.

What you’ll see

You’ll circle clear, quiet water with frequent waterfowl and small critters (chipmunks are practically the welcoming committee). Bison are often in the broader Legion Lake area—occasionally near the road or shoreline—so keep your distance if they wander close. Pines fringe the lake with scattered granite outcrops that give the walk a distinct Black Hills feel.

Logistics and amenities

Start from the Legion Lake Lodge/day-use area off US 16A. This loop sits steps from a beach, picnic areas, a playground, restrooms, a general store, and a boat ramp, making it easy to turn a short walk into a half-day hangout. Dogs are allowed on leash. No trail-specific permit is needed, but a Custer State Park entrance pass is required for vehicles.

Best time to hike

Spring through fall is prime. Summer brings warm temps (and the option to swim or paddle afterward), but also more people—mornings and weekdays are the quiet window. Early fall adds colorful foliage around the lake. In winter, the loop can double as a snowshoe or cross-country ski circuit when snow sticks, though some amenities may be closed.

If you want more

Craving a workout instead of a stroll? Across 16A at Legion Lake Campground there’s a short, steeper trail that climbs and links with the Centennial Trail—distinct from this shoreline loop and a better choice for elevation and sweat.
