How to Ascend the Half Dome Cables Safely


Few hiking experiences compare to standing atop Yosemite’s Half Dome — a granite monolith rising nearly 5,000 feet above the valley floor. But before you soak in that 360-degree view, there’s one final challenge: the infamous Half Dome cables. This last 400-foot ascent tests both your physical and mental endurance. But how do you ascend the Half Dome cables safely? At Discovery Treks, safety is our number one priority, and we’re here to guide you through the best practices for conquering the cables safely and confidently.

What Are the Half Dome Cables?

The Half Dome cables are a set of two steel cables bolted into the granite slope, allowing hikers to pull themselves up the final stretch. Wooden planks are spaced every 10-15 feet to provide footing and brief resting spots. While the incline looks intimidating — and can feel nearly vertical — thousands of hikers safely complete the climb each year with the right preparation.

Safety Tips for the Cables

1. Use Gloves with Grip

A solid pair of gloves with rubber or leather grip can make all the difference. You’ll be pulling your body weight with your arms while maintaining balance with your feet. Avoid cotton gardening gloves — they tend to slip and offer little protection.

2. Wear Grippy Hiking Shoes

Footing is critical. Choose shoes with sticky rubber soles and good tread. Smooth or worn-down soles increase your chances of slipping on the polished granite.

3. Maintain Three Points of Contact

Always keep at least two hands and one foot — or two feet and one hand — in contact with the cables and rock. This stability prevents slips and gives you more control if another hiker bumps into you.

4. Pace Yourself

There’s no rush. Take breaks at the wooden planks and let others pass if needed. Conserve energy and hydrate before the ascent — it’s short but steep and demanding.

5. Stay in Your Lane

Uphill hikers typically stay to the right and downhill to the left, but this can shift based on traffic. Communicate clearly with others and wait for safe passing spots.

6. Know When to Turn Back

Storm clouds? Wet rock? Low energy? These are signs to retreat. Half Dome becomes extremely dangerous when wet, and thunder on the summit can be life-threatening.

Recommended Gear

  • Grippy gloves

  • High-traction hiking boots

  • Harness and carabiners (optional for added safety)

  • Plenty of water

  • Electrolytes and high-energy snacks

  • Weather-appropriate layers

Don’t Forget: A Permit is Required

To protect the trail and manage safety, Yosemite National Park requires permits for anyone climbing the cables. Discovery Treks handles permits for all our guided Half Dome tours, so you can focus on the experience — not the paperwork.
