Yosemite National Park: Hiking Half Dome, Part 1
Yosemite National Park is a crown jewel of America’s many outstanding hiking destinations. This remarkable landscape, deeply loved by naturalist John Muir and photographer Ansel Adams, features breathtaking mountains, deep valleys, majestic meadows, incredible waterfalls and massive granite domes. One of the most impressive of these granite monoliths is also perhaps the most famous hike in Yosemite…the mighty Half Dome guided hike.
There are two ways to go about tackling this exciting and demanding hike. One is via a long day hike roughly 14 miles in length. The other way, and the preferred alternative, is to summit it as part of a longer overnight backpacking trip in Yosemite’s outstanding backcountry. For either option, permits are required and must be obtained in advance. Many adventurers consider it one of the best Yosemite hikes and a true test of skill and endurance.
The Long Day Hike
The day hike option is a relatively grueling, yet incredibly rewarding, trek covering 14 miles roundtrip and an elevation gain of nearly 5000 feet. This is certainly not an endeavor to be taken lightly and should really only be attempted by fit, experienced hikers. Someone in excellent physical shape who is rarely stopping for rest breaks and photo stops can feasibly complete the hike in about 8 hours. Most folks will take 10 to 12 hours, and some will take even longer. Plan to start very early in the morning (first light is a great time), carry about 1 gallon of water per person, and bring plenty of food. You’re going to burn a LOT of calories so you might consider carrying something for breakfast and lunch, as well as a hearty supply of snacks. Take advantage of the cooler temperatures in the morning and keep a steady pace (breaking every hour or so until reaching the summit). Enjoy the views from the top and relax awhile…you deserve it.
On your way back down, feel free to take your sweet time. Downhill hiking can be more taxing on your body than uphill, particularly on your knees and ankles. And considering you have already covered 7 miles and climbed almost a vertical mile, your legs might be a little weary. Trekking poles are a great tool for helping take some the pressure of your knees as you descend and they offer a little more balance as well. It’s probably a good idea to have a flashlight or headlamp with you just in case it starts getting dark on the way back. You will likely find yourself on the trail with quite a few other hikers as daylight fades so don’t worry about being alone out there. Once you arrive back at your starting point, it’s a short stroll (or drive) to Curry Village for a cold beer and some pizza!
Frequently Asked Questions
Planning to hike Half Dome in Yosemite National Park? Here are some of the most common questions hikers ask before taking on this iconic and challenging adventure.
How long is the Half Dome hike?
The Half Dome hike is roughly 14 miles roundtrip when done as a day hike. It includes nearly 5,000 feet of elevation gain and typically takes between 10 and 12 hours to complete, depending on fitness level and pace.
Do I need a permit to hike Half Dome?
Yes. A permit is required for all hikers attempting to summit Half Dome, whether as a day hike or as part of an overnight backpacking trip. Permits must be secured in advance through Yosemite National Park’s official system.
How difficult is the Half Dome hike?
It’s considered a strenuous and challenging hike, best suited for experienced and physically fit hikers. The trail is steep, long, and demanding, especially near the summit where cables assist in the final climb. Preparation, stamina, and proper gear are essential.
How long does it take to reach the top of Half Dome?
Fit, experienced hikers who move quickly and take minimal breaks can reach the summit in around 4–5 hours. Most hikers take 6–8 hours to reach the top, enjoying rest stops and photo opportunities along the way.
What time should I start the Half Dome hike?
It’s best to start at first light—usually around sunrise—to take advantage of the cooler morning temperatures and allow plenty of daylight for the return. Many hikers begin between 4:30 and 6:00 a.m. to ensure they have ample time.
How much water should I bring for the hike?
Plan to carry about one gallon (roughly four liters) of water per person for the day hike. There are no reliable water sources along the upper sections of the trail, so hydration and electrolyte replacement are key to a safe climb.
What should I pack for hiking Half Dome?
Pack high-energy food, plenty of water, layers for changing weather, a flashlight or headlamp, and trekking poles to reduce knee strain on the descent. Gloves with a good grip are also helpful for the cable section near the summit.
Can beginners hike Half Dome?
While possible, it’s not recommended for beginners. The hike requires endurance, strength, and preparation for steep climbs and long distances. Beginners should train with smaller hikes in Yosemite before attempting Half Dome.
Is it better to do Half Dome as a day hike or a backpacking trip?
Both are rewarding. The day hike is a thrilling endurance challenge, while the backpacking option allows more time to enjoy Yosemite’s wilderness, adjust to the elevation, and experience the park’s quieter backcountry.
What’s the best time of year to hike Half Dome?
The cables are typically up from late May through early October, depending on snow and weather. Summer and early fall offer the most stable conditions, but always check current trail and weather updates before your trip.
Backpacking Half Dome
For those looking to stretch out the adventure, consider including Half Dome as part of a
Yosemite backpacking trip. Backpacking provides the chance to acclimatize better, enjoy Yosemite’s pristine wilderness, and explore
other Yosemite hiking trails beyond Half Dome. Adding a night under the stars transforms this already incredible trek into a true wilderness journey.
