Lake Mary is the largest and most popular lake in the Mammoth Lakes Basin. And with good reason. There's plenty of room to paddle out beyond the crowds for unobstructed views of the Mammoth Crest, Crystal Crag, and Mammoth Mountain. There's a public marina at either end of the lake, with ramps and docks for put-in, but access is easy from points all around the lake. Go early in the day, before the winds kick up! Look for wildlife on the shore and amidst the snags on the southeast end of the lake. Stay clear of fishermen long-casting from shore. The lake is part of the town's water supply, so no swimming allowed.
