Overview
The Golden Trout Wilderness occupies the Kern Plateau in the southern Sierra Nevada, a high tableland between 9,000 and 11,000 feet that looks unlike most of California's mountain terrain. Where the rest of the Sierra Nevada is defined by granite peaks and U-shaped glacier valleys, the Kern Plateau is wide, open, and sky-dominant. Meadows stretch for miles between low ridges. Creek drainages cut through the plateau in broad, easy-banked channels. The whole area has a Great Basin quality that sets it apart from everything else in Sequoia National Forest.
This 12-mile loop samples the best of the plateau's character. Starting from the Blackrock Trailhead on the eastern edge of the wilderness, the route crosses two major creek drainages, climbs to the plateau's higher ridgelines with sweeping views, and descends through the South Fork Kern River corridor before looping back. The 2,500-foot cumulative gain is distributed across two climbing sections; neither is relentlessly steep, but the altitude means exertion feels harder than the numbers suggest.
The wilderness is named for the California golden trout, the state's freshwater fish and one of only a handful of native trout species that survive in the Sierra Nevada. The Kern Plateau's isolated creek systems are among the last places where pure-strain golden trout persist. The fish are visible in clear creek pools along several sections of this route. For information on fishing regulations, contact the California Department of Fish and Wildlife before your trip. For overnight stay planning, review our national forest camping permit guide.
The Route
Miles 0 to 3.0 (Blackrock to the Plateau): From the Blackrock Trailhead, the trail climbs gradually west and south across the open plateau grasslands. The terrain feels more like Wyoming than California in this stretch. Wildlife sightings (deer, marmots, golden eagles) are common. The first creek crossing appears at approximately 2.5 miles; the water is clear and cold.
Miles 3.0 to 6.0 (Plateau Traverse): The route follows the plateau's contours through meadow and open lodgepole pine. Trail markers are intermittent; GPS navigation is helpful here. The creek drainages visible in this section hold golden trout. The high point of the loop reaches approximately 10,500 feet in this segment.
Miles 6.0 to 9.0 (South Fork Kern Corridor): The trail descends to the South Fork Kern River, which is wider and slower than the plateau creeks. A good campsite for overnight trips is located near this junction. The river corridor has dense willow and alder scrub in midsummer.
Miles 9.0 to 12.0 (Return to Trailhead): The final three miles climb back to the plateau elevation and follow a more direct return route to the Blackrock Trailhead. The trail is clearer in this section with more consistent signage.
When to Visit
The Blackrock Trailhead is typically accessible from late June through September. Snow lingers on the plateau well into June in most years. July brings peak wildflower bloom and golden trout feeding activity. August and September offer the most reliably clear weather and the smallest snowpack concerns.
Afternoon thunderstorms occur regularly from late June through August. The plateau's open terrain offers little lightning shelter; plan to camp at lower elevations near the creek drainages rather than on the high ridgelines, and schedule ridge traverses for morning hours.
Check conditions and permits at the relevant Forest Service resources before any backcountry trip.
What to Bring
Many backpackers carry 2.5 to 3 liters of water capacity, though water is available throughout the route in creek drainages. Individual needs vary significantly in the high-altitude, dry plateau environment. Filling at reliable sources and treating all backcountry water is standard practice.
Consider bringing:
- Bear canister (required for overnight food storage, see bear canister requirements)
- Layering system for cold nights (temperatures drop to freezing even in July at this elevation)
- Waterproof footwear or gaiters for the creek crossings
- Detailed topographic map and GPS (trail markings are intermittent on the plateau)
- California fishing license and current CDFW regulations if planning to fish
Practical Details
A free wilderness permit (self-issue) is required for overnight trips. Day hiking does not require a permit. A free campfire permit is required for any open fire at any elevation in this wilderness. Leave-No-Trace practices are particularly important in the Golden Trout Wilderness due to the fragility of the native fish habitat. Review our Leave No Trace guide before your trip.
Veterans and active-duty service members planning federal land visits should review veteran benefits for national forests.
Getting There
From US 395 near Olancha, turn west on Blackrock Road (Forest Road 21S03) and follow approximately 25 miles to the Blackrock Trailhead. The road is unpaved for the last several miles and requires a high-clearance vehicle. From the Kern Canyon side, the trailhead is also reachable via forest roads from Kernville, but this route is longer and more complex. Cell service ends well before the trailhead. The town of Olancha has the last reliable fuel and services before the trailhead approach.
