Hiking to Half Dome via the Cables in Yosemite Valley

Hiking to Half Dome via the Cables is one of Yosemite Valley's most thrilling and iconic outdoor experiences. This challenging 14- to 16-mile round-trip hike ascends over 4,800 feet, offering panoramic views and an unforgettable finale: a steep climb up the cable route to the summit of Half Dome. This once-in-a-lifetime adventure draws visitors for its combination of physical challenge and breathtaking scenery, making it one of the most sought-after activities in Yosemite. Due to its popularity and safety concerns, a permit system is in place to regulate access.

Adventure Guide to Hiking to Half Dome via the Cables

  • Trailhead and Route: Begin your journey at Happy Isles in Yosemite Valley, following the Mist Trail or John Muir Trail to Vernal and Nevada Falls. The Mist Trail features stone staircases and close-up views of cascading waterfalls, while the John Muir Trail provides a longer but less strenuous ascent. The hike culminates with the Sub Dome's steep granite switchbacks, leading to the cables section.

  • The Cables Section: The summit push involves ascending a sheer 400-foot granite slope using metal cables bolted into the rock. This section is not for the faint of heart, requiring upper body strength, sturdy footwear, and careful pacing to manage fatigue. Gloves are highly recommended for gripping the cables.

  • Half Dome Summit: At the 8,836-foot summit, hikers are rewarded with unparalleled views of Yosemite Valley, El Capitan, and the High Sierra peaks. The flat granite summit provides ample space to rest, take photos, and soak in the unique vantage point.

Local Insights

The cables system was installed in 1919 to assist hikers with the final ascent. While thrilling, this section can be dangerous during wet weather due to slick granite. Yosemite suggests attempting the hike between late May and early October when the cables are upright. Avoid visiting after storms to ensure safety.

Visitor Tips

  • Permit: Secure a Half Dome permit in advance through Yosemite’s lottery system.
  • Essentials: Bring 4+ liters of water, high-calorie snacks, gloves, a first-aid kit, and a headlamp for early starts or late returns.
  • Travel Time: From Yosemite Valley, the Happy Isles trailhead is a 10-minute drive or shuttle ride.

Awesome, iconic hike! All the water features along the trail are stunning. Yosemite is a great national park. This was my first visit and won’t be my last! I definitely want to hike Half Dome again. It was fun using the cables and people I passed were so nice offering their gloves! I accepted a couple of pairs bc the ones I brought had no grip which helps. Breathtaking views once at the top. Start early, bring headlamps or flashlight in case you’re hiking in the dark before or after.

Background on me: 50 year old female. Lives in Sacramento. In ok shape. Started hiking in March of 2022 when we decided to hike half dome in September. Have done weekend hikes mostly in the Auburn area. Stayed at the Curry Village lodge. Great location for an early morning wake up and go. We got to the trail parking lot at 5:00 am. Lots of cars in the parking lot at that time. Had our headlamps, which were a must. It was chilly so we layered up and headed out. Started up the Mist trail and missed out on seeing the waterfall because it was so dark. Not many people on the trail so we were moving fairly quick. There are bathrooms on the way so make sure you use those even if you think you don’t need to! Once you pass the campground, there aren’t any bathrooms. The trek from the campground to subdome seemed to take forever. I’d have to say that was my least favorite part. I was very nervous about subdome when I saw it from afar. Once we got to it, it was fine. I am short (5’1”) so some of the steps were high for me. There were some parts with no steps so you had to hoist yourself up and walk up the granite. People were coming down while we were coming up. It was easy to get around people or wait in a corner for them to pass. For months I’ve been terrified of doing the cables. I bought a harness and the whole bit. I watched videos and probably shouldn’t have. I’ve never worn or used a harness so “wing it”. I was afraid I was going to hold people up because of my lack of harness experience but thankfully another woman was behind me using one and was slower and I was. After a while it was very easy to use. I had a great time going up. I had great gardening gloves that helped grip the cables and made it much easier. I was surprised that the climbing up wasn’t too hard. There were a couple areas where you have to step up, but it wasn’t terrible if you used the cables and poles. People were nice and waiting for the people coming up. The top of half dome was nice. Unusually flat. We were up there for about a half hour. People were nice and we exchanged taking pictures of each other. A must is to take a picture on the part that looks very scary to go on. People call it the diving board but I understand now that’s on another area of half dome. It seems like it’s narrow but there is a lot of room and I didn’t feel uncomfortable going out on it…And I’m afraid of heights. See pics. We had some snacks then decided to go back down. I started out going backwards because people said that was better. I found it to be more difficult so I went down forward facing. I used my harness on the way down. It’s definitely a different experience to see the people coming up. Everyone going down is happy…fewer people looking happy going up! We waiting a while so people could come up but it was fine. When we got to about a quarter of the way remaining I felt very comfortable and picked up speed. It was very fun. I was still wearing my harness then about 1/8 left I didn’t use it. Cables were awesome. I wanted to do it again! Funny how the part I dreaded the most was my favorite part. There were a couple people that looked like they were really struggling and turned around. There was one girl having an anxiety attack and yelling at “mike” that she couldn’t do it. The walk down sucked after subdome. Having 50 year old joints is no fun. We stopped for snacks and water. Oh yeah water…I had a water pack that held 2 liters. I drank it all before I got to subdome. The BF had one that held 3 liters so I had some of his. Overall it was a great experience. If you’re worried about the cables, take a harness. If you live in Sacramento and want to borrow mine, you’re welcome to it. It’s a small/‘medium. Message me if you do. Lastly, Animals we saw: Beautiful owl, ravens, cutest little chipmunks and lizards. Happy hiking!!

The cables are NOT as hard as they look. They are much scarier to look. You just have to commit, dont look down, dont look on the sides, just look in front of you. You'll need gloves!

I did it in 2022 at age 50. Was awesome. More a test of endurance and grit than anything. I am in good shape but not a mountain climber of anything. We started early 4 am. Made all the difference. We at the cables by 11 am. Spent 80 minutes on top of Half Dome. Worth all the hard work. Amazing views. A nice feather in your cap.

Breathtaking views and a deep feeling of accomplishment and big achievement. Definitely more than just climbing up those cables. Proving to yourself you can reach anywhere you want and get anything. For climbing up its all about upper body strength need to pull thru the cables. Don’t forget gloves with good grip. Boots/shoes with good traction/tread. The cables part is almost vertical so no matter which shoes you have on they will slip. All you need is arm strength to grip the cables with hands. If you have reached to the sub dome part, just build some more courage I am sure you will conquer this. Good luck.
