Face to Granite: Conquering Half Dome's Cable Route
A hands-on guide to the classic Sierra ascent — from falls and granite slabs to the exposed cable finish.
You round a final switchback, legs humming and lungs steadying, and the valley drops away like a hand pulled from a tablecloth. Sun slashes across the polished face of Half Dome, turning its weathered granite into a pale, warm slab that seems to glow from within. Wind tugs at your layers. Below, Vernal and Nevada Falls rush like a pair of white ropes. Ahead: a steep, knuckled slope and two braided cables that rise from the Subdome to the summit — a short, exposed finale that separates hikers from one of North America's most iconic perches.
Trail Wisdom
Start before dawn
Beat the heat and the cable-line by hiking out early; this also reduces thunderstorm exposure in summer.
Secure a Half Dome permit
Cables are regulated—apply via recreation.gov well before your trip or enter the seasonal lottery.
Bring sturdy gloves
Leather or synthetic gloves with grip protect your hands on the steel cables and reduce blister risk.
Plan water carefully
Carry at least 2–3 liters per person; treat or filter refills at seasonal streams if needed.

Conservation Note
Yosemite manages visitor impact with the Half Dome permit system and Leave No Trace policies—pack out waste, use approved food storage, and stay on designated trails.
The Ahwahneechee people lived in Yosemite Valley for generations; the modern Half Dome cable route dates to early 20th-century improvements (first cables installed in 1919).
Seasonal Guide
spring
Best for: Waterfalls, Fewer crowds early season
Challenges: Snow and ice on high sections, Mud on trails
Spring delivers spectacular waterfall flows but expect snow and wet conditions on parts of the trail; cables may open late in the season.
summer
Best for: Cable access, Stable weather, Long daylight
Challenges: Crowds, High daytime heat, Thunderstorms in afternoons
Summer is the most reliable time to find the cables up and dry granite—start early to avoid heat and storms.
fall
Best for: Fewer people, Stable late-season weather
Challenges: Shorter days, Possible early snow at elevation
Early fall often offers the best balance—cooler temperatures and thinner crowds while cables are usually still in place.
winter
Best for: Snowshoeing alternatives, Quiet park experience
Challenges: Cables removed/closed, Technical snow and ice travel required
Winter travel to Half Dome requires mountaineering gear and skills; the cables are typically taken down, making the route unsafe for standard hikers.
Photographer's Notes
What to Bring
Sturdy hiking bootsEssential
Support and traction on granite and uneven trail—vital for the long climb and cable approach.
Gloves (leather or synthetic grip)Essential
Protects hands and improves grip on the cables during the exposed ascent.
Hydration system (2–3L)Essential
Keeps water accessible for a long, strenuous day—more in hot months.
Light insulating layer and shell
Weather can change quickly; a lightweight jacket helps for summit wind and cooler evenings.
Common Questions
Do I need a permit to climb Half Dome?
Yes. A Half Dome permit is required when the cables are up (typically late May–early October). Permits are issued via recreation.gov through a seasonal lottery and daily reservations.
How long and difficult is the hike?
Expect 14–16 miles roundtrip with about 4,800 feet of elevation gain, usually 10–14 hours for a day trip—it's a long, strenuous hike with an exposed cable section at the end.
Are the cables open year-round?
No. Cables are seasonal and often removed in late fall/winter due to snow and ice. Winter ascents require technical mountaineering gear and experience.
Can kids or dogs do the Half Dome hike?
While older, experienced children can summit with supervision, the cables are exposed and not suitable for very young kids; dogs are not permitted on the trail sections above paved Valley trails and are effectively not allowed on the Half Dome route.
What's the best route—Mist Trail or John Muir Trail?
Both reach the same general area; the Mist Trail is steeper and wetter with closer falls views, while the John Muir Trail is longer but gentler—many hikers ascend one and descend the other.
Is climbing the cables dangerous?
The cables are exposed and require caution, good footwear, and calm hands; most accidents are due to weather, crowding, or poor judgment—don't attempt them in wet or stormy conditions.
What to Pack
2–3L water (hydration and heat management), sturdy hiking boots (traction and support), gloves for cable section (hand protection), lightweight insulating layer (summit wind and changing weather).
Did You Know
Half Dome’s summit elevation is 8,844 feet, and the face that defines the peak was shaped largely by glacial action and exfoliation—its current cable route was first installed in 1919.
Quick Travel Tips
Reserve a Half Dome permit early via recreation.gov; use Yosemite Valley shuttles to avoid parking hassles; start before dawn to beat heat and crowds; carry a map and whistle—cell service is limited.
Local Flavor
Yosemite blends Ahwahneechee heritage with Sierra Valley culture; refuel in Yosemite Valley or nearby Mariposa with hearty mountain fare—think grilled meats, warming soups, and local apple or berry pies after a long day on the trail.
Logistics Snapshot
Distance: 14–16 miles RT • Elevation gain: ~4,800 ft • Time: 10–14 hours • Permit: Half Dome cable permit required (seasonal) • Trailheads: Happy Isles (Valley) • Shuttle: Yosemite Valley shuttle service reduces parking stress.
Sustainability Note
Respect the permit system, pack out all waste, use food storage lockers where provided, and minimize group sizes; small choices preserve wilderness access for future visitors.
