Half Dome Cables: Your Ultimate 7-Step Preparation Guide
The granite monolith of Half Dome in Yosemite National Park is one of the most iconic natural landmarks in the world. Standing tall and proud, its sheer face has beckoned adventurers for generations. But for many, the ultimate challenge isn&t just reaching the base; it&s the final, exhilarating, and often intimidating ascent up the famous cables-in-the-ocean/”>cables. As someone who has not only stood atop Half Dome but has also helped countless others prepare for this incredible journey, I can tell you there&s a unique blend of awe and apprehension that comes with staring up at those two parallel lines disappearing into the sky. This article is your comprehensive guide to understanding, preparing for, and safely conquering the Half Dome cables-in-the-ocean/”>cables.
What Exactly Are the Half Dome cables-in-the-ocean/”>cables?
The Half Dome cables-in-the-ocean/”>cables are a system of two metal cables-in-the-ocean/”>cables secured by wooden posts, installed annually to assist hikers in climbing the final 400 feet of Half Dome&s sheer granite face. This innovative, albeit exposed, aid allows hikers to pull themselves up the otherwise impossibly steep, slick granite slab. The system consists of around 60 wooden posts, drilled into the rock, through which the metal cables-in-the-ocean/”>cables are threaded. These posts are spaced about 10 feet apart, creating a “ladder” effect with wooden planks placed between the cables-in-the-ocean/”>cables at intervals, serving as steps. They are typically installed from late May/early June to Columbus Day in October, weather permitting. Outside of this period, the posts are laid flat on the rock, and the cables-in-the-ocean/”>cables are removed, making the climb significantly more dangerous and generally not recommended.
To climb the Half Dome cables-in-the-ocean/”>cables, you absolutely need a permit from Yosemite National Park, which is allocated via a lottery system. Due to the extreme popularity and the need to manage congestion and ensure safety on the cables-in-the-ocean/”>cables, the National Park Service limits the number of hikers allowed on the route each day. There are two main permit lotteries:
- Pre-season Lottery: This lottery takes place in March and awards approximately 225 permits per day for the entire season. It&s highly competitive, so apply with flexible dates if possible.
- Daily Lottery: If you miss the pre-season lottery or your plans change, a small number of permits (around 50 per day) are available through a daily lottery during the hiking season.
You apply two days before your desired hiking date, with results announced the following day.
Always check the official Yosemite National Park website for Half Dome permit information for the most up-to-date details and application deadlines.
Without a permit, attempting to climb the cables-in-the-ocean/”>cables will result in a hefty fine and a potential ban from the park.
Proper gear is non-negotiable for a safe and successful ascent of the Half Dome cables-in-the-ocean/”>cables. The right equipment can be the difference between a thrilling experience and a dangerous struggle. Here&s what you&ll need:
- Gloves: This is arguably the most crucial piece of gear for the cables-in-the-ocean/”>cables. Work gloves (leather or sturdy synthetic) protect your hands from abrasions and provide much-needed grip on the metal cables-in-the-ocean/”>cables. Don&t skimp here; cheap gardening gloves won&t cut it.
Brands like Marmot Work Gloves or similar heavy-duty options are excellent choices.
- Grippy Hiking Shoes/Boots: Your footwear needs excellent traction on slick granite. Leave your worn-out sneakers at home.
Shoes like the Merrell Moab 3 or Salomon X Ultra 4 GTX offer superb grip and ankle support.
- Plenty of Water: The hike to Half Dome is long (14-16 miles round trip) and strenuous. Carry at least 3-4 liters per person, especially on hot days.
A hydration pack like the Osprey Talon 22 is highly recommended.
- Snacks and Food: Fuel your body! Energy bars, nuts, dried fruit, and sandwiches are essential.
- Headlamp: Even if you plan to be off the cables-in-the-ocean/”>cables before dark, unexpected delays can happen. Always carry a headlamp with fresh batteries.
- Small Backpack: To carry all your essentials.
- First-Aid Kit: For minor scrapes, blisters, and emergencies.
- Sun Protection: Hat, sunglasses, and sunscreen. The granite reflects sunlight intensely.
- Rain Gear: Weather in the mountains can change rapidly.
- Navigation: A map and compass, or a GPS device. Many outdoor watches now offer GPS functionality, which can be a lifesaver.

The ascent up the Half Dome cables-in-the-ocean/”>cables is physically demanding and mentally challenging, requiring good upper body strength, endurance, and a strong head for heights. It&s a vertical climb where you&re pulling yourself up using the cables-in-the-ocean/”>cables, with only wooden planks every 10 feet or so for resting your feet. The exposure is significant; there&s nothing but air on either side. Many people find the mental aspect, particularly the fear of heights, to be more challenging than the physical exertion.
The sheer drop-offs can be intimidating. The entire hike to reach the base of the cables-in-the-ocean/”>cables is already a strenuous journey, gaining over 4,800 feet in elevation. You should be in excellent physical condition, accustomed to long hikes, and have no significant fear of heights.
Take your time, focus on your footing, and communicate with those around you.
Safety on the Half Dome cables-in-the-ocean/”>cables is paramount. Always prioritize caution and adherence to park regulations to ensure a safe and enjoyable experience.
- Go One at a Time Between Posts: The park recommends only one person between each wooden post. This prevents the cables-in-the-ocean/”>cables from swaying excessively and reduces the risk of someone being knocked off.
- Maintain Three Points of Contact: Always have two hands and one foot, or one hand and two feet, securely on the cables-in-the-ocean/”>cables or planks.
- Avoid Wet Weather: Do NOT attempt the cables-in-the-ocean/”>cables if the rock is wet or if there is any sign of rain or thunderstorms. Wet granite is incredibly slick, and lightning on an exposed granite slab with metal cables-in-the-ocean/”>cables is extremely dangerous. Check the weather forecast carefully, using resources like the National Weather Service for Yosemite.
- Don&t Rush: Take your time. Step aside on the planks if you need a breather or if faster hikers want to pass.
- Be Aware of Others: Watch out for people coming down as you go up, and vice-versa.
