Black Rock Pass Trail

Overview

Black Rock Pass is a burly, high-alpine gateway on the Great Western Divide in the Mineral King region. Expect a sustained, switchbacked grind to roughly 11,500–11,600 feet with huge payoffs: sweeping views over the Little/Big Five Lakes basins and the craggy Sierra skyline. This is an advanced objective for experienced hikers or backpackers who are comfortable with long days, big vert, and thin air.

Distance and Route Options

The classic west-side approach via the Cliff Creek drainage climbs about 7.9–8.0 miles one way to the pass, with over 4,700 feet of gain. As an out-and-back to the pass, plan on roughly 16.0 miles total. Many hikers fold the pass into bigger itineraries, from an overnight to Pinto Lake (noting bear boxes there) to full-on multi-day loops linking Little/Big Five and Nine Lakes Basin. The ascent is steep, exposed, and largely above treeline near the top—pace accordingly and start early.

What You’ll See

This is quintessential High Sierra: massive granitic walls and domes carved by multiple glacial advances, polished benches, alpine lakes in cirque basins, and stark, wind-scoured ridgelines. Crossing the Great Western Divide gives you a dramatic sense of the park’s split drainages—Kaweah country to the west, the Upper Kern to the east.

Difficulty and Trail Conditions

Make no mistake: this is strenuous. The grade is relentless on the west side, and altitude will amplify the effort. Seasonal reports note occasional downed trees, overgrowth, and water-obscured sections; expect mosquitoes around lakes in mid-summer. Plan your water and sun protection carefully; shade is limited on the upper switchbacks.

Best Time to Hike

Mineral King access is typically late spring through early fall; the road closes in winter. Prime conditions for the pass are usually July–September, once snow has melted from the upper slopes. For photography, early morning light on the climb and late-afternoon alpenglow from camps near Little/Big Five or Pinto Lake are hard to beat. Weekdays see fewer people; this area stays far quieter than front-country favorites.

Wildlife and Precautions

You’re in bear and marmot country. Use proper food storage at camp and take vehicle-protection precautions for marmots at Mineral King trailheads. Afternoon thunder, strong winds, and fast-changing weather are common at elevation—turn around if conditions deteriorate. Acclimatize if you’re coming from sea level.

Permits and Regulations

Overnight trips require a wilderness permit (quota season with entry-point limits). Day hikes do not require a wilderness permit. Group size limits apply, and pets are not allowed on trails in these parks. No bikes or other wheeled devices in wilderness.

Tips

• Stage a high camp (e.g., Pinto Lake or the Five Lakes basins) to make the pass day shorter and more enjoyable.
• Start before sunrise for cooler temps and steadier footing on the long west-side switchbacks.
• Bring head net/repellent in mosquito season and expect variable trail maintenance after heavy winters.
