At the end of Lake Mary Road and the Lakes Basin Path, Horseshoe Lake is a popular recreation area and staging point for the Mammoth Pass and Mcleod Lake trails. The Lake Basin truly delivers hundreds of visitors daily, many with bikes to ride the only mountain bike trail in the Lakes Basin. The area is distinguished by strikingly dramatic tree kill from carbon dioxide seeping through the surface after a swarm of small earthquakes in 1989-1990.
