Taboose Pass to Upper Basin

OVERVIEW

Taboose Pass to Upper Basin is a strenuous 26.4 mile out-and-back located within the Sierra Nevada. The Taboose Pass Trail is one of the most demanding east-side routes into the Sierra Nevada, gaining over 6,000 feet in just 8 miles before reaching Taboose Pass (11,362’). From there, the trail descends into Upper Basin, a stunning alpine expanse nestled beneath the towering peaks of the John Muir Wilderness and Kings Canyon National Park. This remote and strenuous route rewards hikers with solitude, breathtaking high-country scenery, and access to the John Muir Trail (JMT) and Pacific Crest Trail (PCT).

DESCRIPTION

The hike begins at the Taboose Pass Trailhead (5,480’), located off Highway 395 near Big Pine. The trail wastes no time gaining elevation, following Taboose Creek through exposed desert terrain. The lower section is hot and dry, with sparse vegetation consisting of sagebrush, rabbitbrush, and pinyon pines. Water sources are limited in the early miles, so carrying enough water is crucial.

As you climb, the landscape transitions into aspen groves and lodgepole pines, offering some much-needed shade. The trail remains steep, with multiple creek crossings that can be challenging during early summer snowmelt. The final push to Taboose Pass involves loose rock and switchbacks, but reaching the pass provides stunning panoramic views of the Sierra Crest, Arrow Peak (12,959’), and Split Mountain (14,064’).

Beyond the pass, the trail descends gradually into Upper Basin (11,000’), a vast and open subalpine valley surrounded by rugged peaks. Here, the vegetation consists of grassy meadows, wildflowers, and scattered whitebark pines. Marmots, pikas, and golden eagles are commonly seen, and the area is prime habitat for Sierra Nevada bighorn sheep. The basin also provides access to the Sierra High Route in addition to the John Muir Trail/PCT, where hikers can explore further or set up camp near one of the many pristine alpine streams. This area is popular amongst peak baggers and off-trail adventurers. 

After soaking in the views, return the way you came, bracing for the steep descent back to the valley floor.

SAFETY AND CONSIDERATIONS

• Wilderness Permits: Required for overnight trips. 

• Bear Canisters: Required for overnight stays.

• Upper Basin is a fragile environment and visitors must follow Leave No Trace guidelines.

• Difficulty: Extremely strenuous due to steep elevation gain and exposure.

• Weather: Sudden storms and high winds are common above treeline. Be prepared for extreme temperature shifts.

• Water Sources: Filter all water. Taboose Creek and Upper Basin streams provide reliable sources, but availability may vary late in the season.

• Altitude: The rapid ascent can cause altitude sickness—acclimatize properly before attempting.

PARKING AND ACCESS

• Trailhead: Access via a rough, washboard dirt road off Highway 395. High-clearance vehicles are recommended, but sedans can typically make it with caution.

• Parking: Limited space at the trailhead; arrive early on weekends.

BEST TIME TO HIKE

The best window is late summer to early fall (July–September), when snow levels are low and creek crossings are manageable. Early season hikes can be dangerous due to lingering snow and high water levels.

This challenging but rewarding route is ideal for experienced hikers seeking solitude and dramatic Sierra scenery.
