Few hikes in the United States are as iconic—or as rewarding—as the trek up Half Dome in Yosemite National Park, California. With its dramatic granite face rising nearly 5,000 feet above Yosemite Valley, Half Dome offers hikers a challenge that’s matched only by its breathtaking views. If you’re looking for a trail that combines physical endurance, natural beauty, and a true sense of accomplishment, Half Dome deserves a spot at the top of your bucket list.
Trail Overview: What to Expect
The Half Dome hike is not for the faint of heart. It’s a strenuous, full-day adventure that covers approximately 14 to 16 miles round-trip (depending on your starting point) with an elevation gain of about 4,800 feet. Most hikers begin from the Happy Isles Trailhead in Yosemite Valley, and the journey typically takes 10 to 14 hours to complete.
Along the way, you’ll pass through a variety of landscapes—from misty waterfalls and shaded forests to exposed granite ridges. Key highlights include Vernal Fall, Nevada Fall, and the subdome before reaching the final ascent: the infamous Half Dome cables. These cables allow hikers to climb the last 400 feet to the summit, a daunting but exhilarating experience with panoramic views of Yosemite Valley and the High Sierra.
Permit Requirements and Fees
To preserve the trail and ensure safety, the National Park Service requires a permit to hike beyond the subdome and ascend the cables. Permits are distributed via a preseason lottery held each March through Recreation.gov. A limited number of daily permits are also available through a daily lottery two days before your intended hike.
Here’s what you need to know:
- Permit Cost: $10 to enter the lottery, plus $10 per person if selected.
- Group Size Limit: Up to 6 people per application.
- Park Entrance Fee: $35 per vehicle (valid for 7 days).
Apply early and be flexible with your dates to increase your chances of securing a permit.
Best Time to Hike Half Dome Yosemite, CA
The Half Dome cables are typically up from late May to mid-October, depending on snow conditions. The best time to hike is between June and September when the trail is mostly clear of snow and the weather is more predictable.
July and August offer the warmest temperatures but also draw the most crowds. For fewer people and cooler temperatures, aim for a weekday in early June or late September. Always check the official Yosemite website for current trail and cable conditions before you go.
Trail Conditions and Difficulty
This is a challenging hike that requires excellent physical fitness and mental preparation. The trail surface varies from paved paths near the trailhead to steep, rocky switchbacks and granite staircases. The final ascent up the subdome is steep and exposed, and the cable section requires upper body strength and a good head for heights.
Hazards to be aware of include:
- Exposure: The cable section is not for those afraid of heights.
- Weather: Thunderstorms are especially dangerous on the cables—don’t attempt the hike if storms are forecasted.
- Wildlife: Bears are present in Yosemite; store food properly and follow Leave No Trace principles.
- Water Crossings: The Mist Trail can be slippery, especially near Vernal Fall.
Safety Tips and Recommendations
- Start early—ideally before sunrise—to avoid afternoon storms and ensure you have plenty of daylight.
- Stay hydrated. Carry at least 3 to 4 liters of water per person.
- Use gloves for the cables section to protect your hands and improve grip.
- Know your limits. If you feel unsure at the subdome or cables, it’s okay to turn back.
- Check weather forecasts and trail conditions before your hike.
