Adventure Tips
Secure Your Half Dome Permit Early

Start Before Sunrise
Begin your hike early to avoid the intense midday sun and crowded cables. Cooler temperatures and lighter traffic improve safety and enjoyment.
Hydrate Generously

Half Dome Cable Route: Your Essential Guide to Yosemite’s Ultimate Adventure
Rising sharply above Yosemite Valley, Half Dome beckons those looking for an unmatched blend of challenge and reward. Hiking the Half Dome via the cables is an experience that tests your endurance and focus, drawing you into a raw dialogue with the granite giant itself. The journey covers roughly 14 to 16 miles round trip, depending on your starting point, with an elevation gain of about 4,800 feet from Yosemite Valley floor.
Your trek begins where the forest thickens—the Merced River’s murmurs daring you onward—as you move past Vernal and Nevada Falls. The trail’s terrain shifts between well-trodden granite slabs and shaded woodland paths, each step building momentum toward the iconic ascent. The air sharpens as you reach the subdome, a broad granite expanse that feels like the mountain’s last breath before the cables stretch above.
The cables stand as both lifeline and gateway, bolted firmly into the granite, inviting hikers to grip and climb with sure steps. At this point, rock is fiercely itself—unyielding and alive under your hands, demanding respect. Safety is paramount: each climber must secure footing and steady balance as the trail narrows and the drop surrenders nothing.
Reaching the summit, you’ll find yourself on a towering slab overlooking Yosemite’s vast expanse. Wind and sky converge here, framing views that make every grueling mile worth the effort. Humboldt pines bark softly below; clouds drift in currents, almost inviting a moment’s pause.
Preparation is essential. Hydrate thoroughly before and during the hike, carry adequate water (minimum 3 liters), and wear sturdy, grippy footwear. Start pre-dawn to avoid the afternoon heat and crowd buildup. Remember, the cables section is closed during wet or icy conditions—respect the mountain’s demands.
Although rewarding, the Half Dome hike is not casual. You’ll need fitness, focus, and proper gear to meet the challenge safely. Yet for all its difficulty, the route offers a uniquely tangible partnership with one of nature’s toughest puzzles. It’s an adventure that doesn’t just ask you to climb—it requires you to listen, adapt, and honor the mountain’s fierce character.
