At 8,600 feet, Twin Lakes - really a single lake with a narrow choke in the middle - is fed by the beautiful and dramatic Twin Falls. The only lake accessible by car year-round, Twin Lakes offers camping, an outdoor wedding chapel, a general store, fishing tackle and boat rentals and a historic lodge and restaurant. 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.
