Half Dome: The Ultimate Yosemite Hike
Everything you should know about the Half Dome Hike
Yosemite National Park is one of America's most famous National Parks. The park is an icon and an international travel destination for millions of people every year. If you haven't been to Yosemite, check out our How to Visit Yosemite Guide.
Yosemite is known for it's famous cliffs, majestic waterfalls, and storybook like rivers. Out of all of the rocks in the park, there is one that sticks out the most. Literally.
Why do the Half Dome Hike? Half Dome is Yosemite's most distinguishable sight and for a good reason. Half Dome is dauntingly huge and unique. The rock sticks out of the Earth like it doesn't belong. And the best part about it? You can climb to the top.
Planning and Preparing for the Half Dome Hike
When I say climb, I'm half right and half wrong. You can quite literally summit Half Dome by rock climbing, whether with ropes or free climbing (yikes). But this page isn't about that kind of climbing. If you want, you can find out more about climbing the Northwest Face of Half Dome here.
For most people, Half Dome is a 16 mile round trip hike by foot. The very last stretch of the hike is not-passable if you don't have a permit, and there's a ranger waiting to check. Only 300 people per day are allowed up the last stretch during season, when the cables are up. Rangers take the cables down during the cold season.
You can apply for a Half Dome Permit here or by calling 877-444-6777. It's lottery style. Apply as soon as you know you're going. There's also a daily lottery, so if you get rejected, apply again or have a friend apply again a couple days before your trip.
We got rejected the first time we applied but were lucky when we applied again two days before. More information about the Half Dome Permit can be found here. Most people apply for Saturday, so i you can, apply for Sunday or a weekday.
If you're a backpacker, you don't need to apply/reserve if you have the appropriate wilderness permit. They reserve spots for backpackers with the permit each day. Ask for the Half Dome Permit when you pick up your Yosemite Overnight Wilderness Permit.
Finally, don't forget to check the weather before you trip!
How to hike Half Dome
So you want to summit Half Dome! It's going to be an almost 20 mile hike depending where you start your walk, which trail you take (Mist Trail or John Muir Trail), and where you stop along the way. The hike will take at least 6-8 hours depending how fast you walk. It's better to leave very early and take it slow. Before your journey, stop by the visitor center and get a map. Guides at the visitor center can also tell you if the Half Dome hike is right for you, whether you have enough water, and whether it is too late in the day or not.
