Yosemite National Park is absolutely ginormous and it is pertinent that you acquire proper accommodations while staying in the area. If you’re hiking Half Dome, you’ll definitely want to stay in Yosemite Valley at either the Ahwanee, Half Dome Village, or preferably — Little Yosemite Valley.
Make reservations at the Yosemite Website — If they’re full try here
Little Yosemite Valley requires a wilderness permit, but not a campground reservation. Wilderness permits, like Half Dome permits, are drawn in a lottery. There is a wilderness permit office in Yosemite Valley. 40% of permits are handed out at the last minute and 60% are acquired ahead of time. If you’re lucky enough to acquire a permit, you’ll be 3.5 miles from the summit of Half Dome.
If you weren’t able to acquire a wilderness permit, there are still a few options for you. The Ahwahnee is the nicest hotel in Yosemite, but it charges upwards of $500/night for rooms. The other option is Half Dome Village (where we stayed), which is about 1 mile from the trailhead. Half Dome Village has cabins and tents with double beds or single beds, a bar, restaurant, and grocery store. *Note: If you can’t get a reservation on your first try, call and check online every single day. Reservations open up constantly as people cancel their reservations.
