The trail is gorgeous. We went for 2 nights. First night we slept by the Gem lake. second night by the Thousand Island Lake. All together the trail is a little more than 20 mi. its November, so at night the temperature dropped very low, to around 10F. However, during the day hiking was warm enough. There is no developed campgrounds, so you can camp almost anywhere. there is plenty of water, so there is no need to carry lots of water with you. Waugh lake is not really a lake because of the dam, its dried. Our dog was super happy with the hike, too. We picked up permit, maps and bear canister at Mammoth Lakes Welcome Center.
