Up to the Cable: Conquering Half Dome’s Granite Shoulder
A late-summer ascent that tests fitness, nerve, and judgment—rewarding climbers with one of Yosemite’s most iconic panoramas.
The early light in Yosemite Valley has a way of turning granite into a living thing. On the trail to Half Dome the rock breathes and shifts as the sun climbs; what looked cold and indifferent at dawn glows like a patient animal waking, offering you an invitation and a test. For many, the hike to Half Dome is the trip that reorients how they measure effort—16 miles of switchbacks, meadows, waterfalls, and a final 400-foot ascent on steel cables that lean the human body up against the mountain.
Trail Wisdom
Secure a permit
Half Dome cable permits are required during the cable season (typically late May–October); enter the lottery or reserve in advance to guarantee access.
Start before dawn
Begin early to avoid heat on the exposed slabs, reduce crowding on the cables, and give yourself margin for the long return.
Gloves for the cables
Leather or synthetic-grip gloves reduce hand fatigue and protect against hot metal and rough rock on the final ascent.
Hydrate and filter
Carry at least 3 liters and a lightweight filter—water sources exist but can be crowded or seasonal.

Conservation Note
Yosemite uses a permit system and managed trail access to reduce erosion and human impact; practice Leave No Trace and honor food-storage rules to protect wildlife.
The Ahwahnechee people lived and traveled through this landscape for centuries; the Half Dome cable route appeared in the early 20th century as Yosemite’s recreational footprint expanded.
Seasonal Guide
spring
Best for: Waterfalls at peak flow, Cooler subalpine air
Challenges: Snow and icy patches on higher sections, Unpredictable weather
Spring showcases roaring waterfalls and green meadows, but lingering snow can make the upper trail and cables hazardous—check park conditions before attempting.
summer
Best for: Cable route access, Stable daylight for long hikes
Challenges: High crowds and heat on exposed slabs, Sun exposure and limited shade
Summer is peak cable season with reliable access; expect crowds and bring sun protection and plenty of water.
fall
Best for: Fewer crowds, Crisp air and clearer views
Challenges: Shorter daylight hours, Early-season snow possible late in fall
Fall often delivers cooler temperatures and thinner crowds—an excellent time if you secure a permit and mind daylight windows.
winter
Best for: Snow-clad landscapes, Solitude for experienced parties
Challenges: Snow and ice on the cables and slabs, Closed cable access and increased technical risk
Winter conditions make Half Dome a technical undertaking; the cables are usually not maintained, and only expert, well-equipped parties should attempt ascents.
Photographer's Notes
What to Bring
Hiking boots with sticky rubberEssential
Give traction on granite slabs and support on long uphill sections.
Cable glovesEssential
Protect hands and improve grip on metal cables and rough rock.
3–4L hydration systemEssential
Adequate water is critical; hydration packs keep hands free for scrambling.
Lightweight first-aid & emergency kitEssential
For blisters, minor injuries, and unexpected delays on a long route.
Common Questions
Do I need a permit to climb Half Dome?
Yes—day-use permits are required for the cable route during the staffed cable season (typically late May to early October). Obtain them through the National Park Service lottery or day-before processes if available.
How hard is the cable section?
The cable pitch is steep (roughly 400 vertical feet) and exposed; while not technical climbing, it requires physical confidence, two hands on the cables, and steady footing on smooth granite.
Can beginners do Half Dome?
Strong beginners who train for long uphill days, secure a permit, and prepare for exposure can succeed—consider hiking shorter Yosemite classics first to build experience.
When is the best time of day to summit?
Early morning reduces heat and crowding; aim to be on the cables before mid-morning for the most comfortable conditions.
Is it safe in thunderstorms?
No—lightning on exposed granite is dangerous. Descend immediately if storms approach; check weather before you go.
Are there alternatives if cables are closed?
Clouds Rest offers a similarly dramatic vantage on a longer route, and the Panorama and Glacier Point trails provide high viewpoints without cable exposure.
What to Pack
Sturdy hiking boots (traction on granite), 3–4L water or a reliable filter, cable gloves (hand protection and grip), layered clothing (temperature swings between valley and summit)
Did You Know
Half Dome’s shape was carved by glacial action during the last ice age; the dramatic sheer face is the result of one side being plucked away by ice, leaving the rounded ‘half’ dome.
Quick Travel Tips
Book permits early; start before sunrise; carry extra water and snacks; check NPS trail conditions the morning of your hike.
Local Flavor
Yosemite Valley blends park history and hospitality: pick up supplies at Curry Village or dine at the Ahwahnee Dining Room to taste local foraged flavors and classic mountain fare before or after your climb.
Logistics Snapshot
Distance: 14–16 mi RT | Elevation gain: ~4,800 ft | Permit: required (cable season) | Difficulty: challenging | Start: Happy Isles/Valley floor
Sustainability Note
Permits reduce crowding and trail erosion—pack out all waste, use park-designated restrooms, and store food properly to minimize bear encounters and ecosystem impact.
