At 8,600 feet, Twin Lakes--really a single lake with a narrow choke in the middle--is the lowest lake in the Lakes Basin and the only one accessible by car year-round. Nestled between Panorama Dome and the steep southern flank of Mammoth Mountain, Twin Lakes is a popular fishing destination and the source of Mammoth Creek. There is a busy campground here with campsites on both shores, a historic lodge and restaurant, an outdoor wedding chapel, a general store offering basic supplies, fishing tackle and boat rentals and, in winter only, a world-class fee-based cross-country ski center.
