Ascending Half Dome: A Practical Guide to Yosemite’s Iconic Summit
Half Dome stands as Yosemite Valley’s most iconic challenge, beckoning hikers with its steep ascent and grand views. This practical guide equips adventurers with essential details and savvy tips to safely experience its breathtaking summit.
Trail Tips
Start Early to Beat the Heat
Begin your hike before dawn to avoid intense midday sun and reduce crowd congestion on the cables section.
Use Good Grip Footwear
Choose hiking boots or trail shoes with firm grip to handle slippery granite and uneven surfaces safely.
Hydrate Continuously
Carry at least three liters of water per person; refill at available streams after filtering to stay properly hydrated.
Respect the Cable Climb Rules
Only climb the cables when conditions are safe; avoid attempts in rain or wetness to prevent slips.
Ascending Half Dome: A Practical Guide to Yosemite’s Iconic Summit
Hiking to the peak of Half Dome in Yosemite Valley is an experience that tests your stamina and rewards with one of California’s most breathtaking panoramic views. The trail stretches roughly 16 miles round-trip with an elevation gain of about 4,800 feet, starting through shady forest trails that silently witness your steady climb. Along the way, the Merced River often dares you with its cold, rushing currents, urging you to keep moving forward.
The hike’s terrain shifts constantly—from root-laden forest paths to exposed granite slabs that absorb the sun’s strength. The final ascent, the infamous Half Dome cables section, confronts you with a steep, chain-assisted climb that demands both mental focus and physical readiness. Here, the rock isn’t just a surface; it’s a living challenge, smooth yet formidable, commanding respect.
Planning your hike requires more than enthusiasm. Start early to avoid midday heat and crowds, and equip yourself with sturdy shoes that grip granite and roots alike. Hydration is crucial—water sources can be scarce later in the trail, so bring at least three liters per person and consider a filtration system if refilling along the way. A layered approach to clothing prepares you for sudden shifts in Yosemite’s mountain weather.
Upon reaching the summit, the view extends in every direction: Yosemite Valley sprawled below, El Capitan standing proud to the west, and the Sierra Nevada mountains framing distant horizons. Here, time seems to pause. The wind carries a cool determination, and the sun paints light that is sharp and alive. Enjoy the moment but prepare carefully for the return journey—descent can be strenuous and requires steady footing.
Half Dome demands more than steps; it requires respect for a force of nature that is fiercely itself. It offers unmatched beauty to those ready to meet its challenges with preparation and determination.

Frequently Asked Questions
Do I need a permit to hike Half Dome?
Yes, a permit is required for all hikers to ascend the cables to Half Dome’s summit. Permits are issued via a lottery system from late May through early October.
How difficult is the cable section at the summit?
The cable section is steep and exposed but equipped with two metal chains for support. It requires surefootedness, upper body strength, and caution, especially in wet or crowded conditions.
Are there water sources along the trail?
Water is available at several points, including the Vernal and Nevada Falls areas, but it’s essential to carry enough water and purify any refills as natural water can contain pathogens.
What is the best time of day to start the hike?
Starting before sunrise is best to avoid heat, secure a parking spot, and beat the crowds on the cables climb.
Is the hike suitable for children or inexperienced hikers?
Due to its length, elevation gain, and technical cable climb, it’s generally recommended for experienced, well-conditioned hikers. Careful judgement is advised for younger or less experienced individuals.
What should I do if weather changes suddenly on the trail?
