The Yankee Springs Deep Lake Unit Mountain bike trail offers riders a natural feeling trail through the woods around Gun Lake. The staging area provides ample parking with changing rooms and a pit toilet. There is no water available at the staging area. The park also offers rustic drive-up camping, which is $13 per site with a Michigan Recreation Pass.
The trail consists of a 2-mile warm-up loop, which is as equally technical as the longer main loop. The distance of the main loop can be reduced with the use of shortcuts that are well-labeled throughout the trail. The trail contains countless roots, rock gardens and steep, slippery up-and-down sections requiring a moderate level of skill to ride safely. In the dry summer months, sections of the trail can have deep sand for stretches up to 200 yards. The trail is in its prime during the spring months before it dries out.
