Half Dome
Half Dome is a legendary granite formation in Yosemite National Park, California. Each summer, cables are installed so hikers can ascend the final steep granite slope to reach the summit, revealing panoramic views of Yosemite Valley and the High Sierra. This hike typically spans 14–16 miles round trip, depending on the trailhead. Our Popular Trails page covers other iconic U.S. day hikes if further exploration is of interest.

1. Permit System & Lottery
Yosemite National Park requires a permit for the Half Dome cables. Most are distributed through a lottery in March, with additional “daily lotteries” during the season.
2. Route Options
Many start in Yosemite Valley via the Mist Trail, passing Vernal and Nevada Falls. Others choose the John Muir Trail to skip the steepest segments. Both converge near the subdome before the cables. Hiker Resources covers route planning for mountainous regions if extra detail is needed.
3. Gear & Safety
Gloves help grip the cables, and sturdy footwear is essential. Early starts can avoid afternoon thunderstorms. The last granite section is quite steep—turn around if conditions are wet or storms approach. For suggested gear like gloves or traction, see Gear Lists.
4. Best Times to Hike
Typically, the cables are up from late May to early October, contingent on snowpack and park directives. The busiest months often fall in July and August. Checking Yosemite’s official site for exact cable installation and removal dates is always advisable.
5. Water Sources & Resupply
Water is usually accessible near Vernal/Nevada Falls, but it should be filtered or treated. There’s no water at the summit. Many hikers carry 2–3 liters in hot weather. Hiker Resources includes more information on water management and day-hike refills.
6. Respecting Yosemite’s Rules
Yosemite imposes strict protections. Stay on designated trails, pack out all trash, and follow permit guidelines. Crowding can happen, so courtesy on the cables and other narrow sections helps everyone.

The info here is general and may shift with conditions. Always check Yosemite’s official website for updated details on cable status, permits, and safety bulletins. The Hiker Resources section offers a broader look at best practices before tackling major hikes.
