A truly beautiful lake to walk around. The trail is easy, though there's a bit of a climb and a narrow cliff.

The Needles Highway is a 14-mile road that is often called the most scenic road in the world. It passes through pine and spruce forests, meadows surrounded by birch and aspen, and rugged granite mountains. The road’s name comes from the needlelike granite formations that seem to pierce the horizon along the highway. The road was planned by former South Dakota Governor Peter Norbeck and before it was constructed it was considered impossible to build. However, the road was completed in 1922 and is now a very popular destination.
