Half Dome Hiking Guide — Yosemite Trail Essentials

Most hikers reach Half Dome via the Mist Trail or the John Muir Trail out of Yosemite Valley. The common loop starts at the Happy Isles/Lower Yosemite Fall trailhead (approx. trailhead coordinates: 37.7339, -119.5586) and climbs past Vernal and Nevada Falls before the long push to Little Yosemite Valley and the Half Dome sub-dome. Expect rough granite slabs, steep switchbacks and a long approach—plan for about 14–16 miles round trip with roughly 4,800 ft of elevation gain on the classic route. Alternate options include a longer John Muir Trail approach that trades stair-step steepness for steadier grades. Want a guided ascent? Hire local Yosemite climbing guides if you prefer an organized group, instruction on the cables section, or a rope-augmented summit push.

The cables are typically up from late May through early October, depending on snowmelt and weather; the National Park Service posts exact dates each season. Outside this window the summit can be icy and extremely hazardous without technical gear. Summer brings the most predictable conditions but also the biggest crowds and hottest valley temperatures—start before sunrise to avoid heat and afternoon thunderstorms. Spring offers high flows over Vernal and Nevada Falls (slick granite and higher spray), while fall narrows crowds and can provide crisp, clear long-distance views. For permit windows and current trail advisories check Yosemite National Park updates and, if you want expert planning help for a specific season, consult local Yosemite mountaineering guides through The Adventure Collective.

This is a long, strenuous day hike that needs planning. Footwear: stiff-soled hiking boots or trail runners with sticky rubber for steep granite. Gloves with grip are invaluable on the cables; many hikers use leather or synthetic work gloves with a reinforced palm. Pack layers—temperatures swing drastically between valley floor and summit. Essentials include 3–4 liters of water or a reliable filtration plan for refills, high-calorie snacks, a headlamp for early starts/late finishes, a compact first-aid kit, sun protection, and a lightweight wind shell. If you’ll be out after dark or crossing high snow patches, bring a map, GPS, and an emergency bivy. Permits are required for the cables section—acquire them in advance via the park permit lottery. For guided logistics or to rent technical gloves and other specialized gear, reach out to vetted local Yosemite hiking guides who coordinate gear and permits.

Safety is paramount: the cables are physically demanding and slippery when wet. Never attempt the cables during lightning, heavy rain, or when icy. Respect chain etiquette—descend cautiously and yield when necessary. The park requires a permit to ascend the cables; a separate wilderness permit is needed if you plan to camp overnight in the backcountry. For photos, wide-angle lenses capture the scale of Yosemite Valley and Half Dome; bracket exposures for high-contrast scenes and use a polarizer to deepen sky color. Note that drones are not allowed in national parks. If you want hands-on instruction on safe cable technique or photography at elevation, hire experienced professionals via The Adventure Collective’s vetted network of local Yosemite climbing guides who can combine safety coaching with route advice.
