Permits to hike to the top of Half Dome are required seven days per week when the cables are up, even for backpackers with wilderness permits. The quota for Half Dome permits for backpackers is 75 permits per day (50 available by reservation and 25 available two weeks in advance). The cost for Half Dome permits is $10 per person, payable at a wilderness center the day of or day before your trip, and is therefore not refundable.
Reservations for Wilderness Permits & Half Dome Permits
While making a wilderness permit reservation, be sure to specify that you want Half Dome permits. If Half Dome permits are available and Half Dome is reasonably part of your itinerary, you will receive a reservation that includes them. Half Dome permits received in this way will be valid for all dates your wilderness permit is valid.

Can I get a wilderness permit that includes Half Dome and use it for a day hike?
No. Half Dome permits associated with wilderness permits are not valid for day hiking to Half Dome; they are only valid for backpackers.
I have a wilderness permit for an itinerary that travels near Half Dome. Can I use a Half Dome day hiking permit?
Yes, you may compete in the Half Dome permit lotteries. However, Half Dome permits for day hikers are only valid on the date specified on the Half Dome permit. You may also try for a first-come, first-served Half Dome permit, as described above.
I have a Half Dome permit but want to camp in Little Yosemite Valley. Do I need a wilderness permit?
