The old Big Oak Flat Road, now closed to cars, drops a steady 500 feet through mixed conifer forest to reach Tuolumne Grove's two dozen giant sequoias. It's the less crowded alternative to Mariposa Grove, with the same towering trees but a fraction of the crowds — though you'll earn the visit with that climb back up.

Overview
This is sequoia viewing without the circus. While tour buses queue for Mariposa Grove, Tuolumne Grove sits quietly along the old road grade, accessible only on foot. The experience feels more like discovering something than visiting an attraction. You walk the former Big Oak Flat Road — a paved surface that's been reclaimed by the forest — through sugar pines and white firs until you reach the grove.
The trees here aren't quite as massive as their southern cousins, but they're still giants that require neck craning and stepping back to take in. The grove holds about two dozen mature sequoias, including "Big Red" and the old "Tunnel Tree" that drivers once squeezed through. A half-mile nature loop winds among the trees once you reach the grove floor.
What to Expect
The trail starts at 6,200 feet and drops steadily for a mile. The grade isn't brutal, but it's persistent — think long, easy switchbacks rather than steep pitches. The paved surface makes for straightforward walking, even when wet. Sugar pines and white firs line the route, with the forest canopy providing consistent shade.
Once you reach the grove, the terrain levels out. The sequoias cluster in a natural depression where soil conditions favor their growth. The trees create their own microclimate here — cooler and more humid than the surrounding forest. The nature loop is easy walking on soft dirt paths.
The return trip is where you pay the toll. That 500-foot drop becomes a steady climb back to the trailhead. It's not technical, but it's a workout. Budget extra time for the return — the mile back up typically takes longer than the mile down.
Tips & Logistics
The parking lot sits half a mile east of Crane Flat on Tioga Road. It's small and fills fast during summer months. Arrive early or consider visiting during shoulder seasons when the crowds thin out. Pit toilets are available at the trailhead, but there's no water source anywhere along the route or in the grove.
Winter changes the character completely. Tioga Road stays plowed to the trailhead, making this a popular snowshoe destination. The grove under snow is spectacular, but expect icy conditions on the paved surface. Microspikes are essential for winter visits.
Dogs are allowed on the main trail and paved portions of the grove, but not on the side trails that branch off the nature loop. Keep them leashed throughout.
The grove is open year-round, but the best window is April through October when conditions are most predictable. Summer brings the heaviest crowds but also the most reliable weather. Spring and fall offer cooler temperatures and fewer people, though you might encounter snow at higher elevations.
Pack water for the climb back up — there's none available in the grove. The round trip typically takes 1-2 hours, but allow extra time if you want to explore the nature loop thoroughly or if you're visiting with kids who might need breaks on the return climb.
