We secured reservations for the camp below the lookout from the Park. You have to do this when there is still snow for water. We melted snow at lookout and had our dinner up there. Views are amazing! We were there before it was staffed for the season. My mom had always wanted to go there as she loved Jack Kerouac the author who was a lookout there so some of her ashes made it there. Views are incredible, and it was really special due to my mom talking about it. Wish I would have taken her up there. This was my 100th lookout site/structure so it was good I had a special crew with us. The boat is kind of expensive so get 6 people if you can. Would go back if possible someday. Now I'm at 260 and only Adams remains for the final structure to visit. -- Desolation Lookout deserves some elaboration. This is a simple trail once you get to the trail head. To get there, you must either hike a full day on the East Bank trail. Which is a very nice trail. Or arrange for the water taxi, which is a flat rate to the destination and is best split with up to six passengers. Either way, you must arrange for permits to camp at Marblemount. We elected to take the boat with 5 in our party and then stayed at Desolation Camp. There is only one water source part way up to camp, from there we melted snow. Do this in late June when the snow has melted enough to hike, but still enough to provide a water source.
