Pothole Dome to Tuolumne Meadows — Tioga Road Backcountry Spur via Glen Aulin High Sierra Camp
Granite sky country above 8,600 feet.
Tioga Road is one of the highest paved passes in California, but the real story is what branches off it — specifically the rough spur roads threading through Tuolumne Meadows toward Lembert Dome, Soda Springs, and the backcountry trailheads that access Glen Aulin and the Grand Canyon of the Tuolumne. The meadow floor sits at 8,600 feet and the surrounding domes of pale granite climb another thousand feet above you. Dog Lake Road and the Lembert Dome parking area access routes are maintained dirt that any high-clearance rig handles easily, but the shoulder pullouts and dispersed zones deeper into the backcountry get rougher. Keep an eye on the seasonal closure gates — the NPS locks these spurs hard when snow flies, which can be as early as October and as late as June.
This is not a technical trail — it’s a high-clearance moderate with altitude doing most of the filtering. A stock SUV or truck with clearance handles it, but you need a Yosemite reservation or annual pass to enter the park at all during the peak season window. Fuel in Lee Vining before entering — there’s nothing inside the park. Cell service drops to zero past the entrance kiosk. Best window is July through September. What you get out of it is genuine Sierra subalpine solitude on the edges of one of the most visited parks in the country — and most day-trippers never leave the pavement.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this trail without any mods?
Yes — a stock high-clearance 2WD truck or SUV can manage the terrain. Lifted rigs aren't required, but low-clearance vehicles like sedans or standard crossovers will drag on the rocky sections near the backcountry spur approach.
When does Tioga Road actually open, and is there a hard close date in fall?
Tioga Road typically opens in late May to early July depending on snowpack — 2023 didn't open until late June. It closes at first significant snowfall, usually October, sometimes earlier. Check NPS road conditions the day before you go; closures happen fast and without much warning.
Do I need a permit to drive and camp here, or just a park entry pass?
You need a Yosemite park entry reservation or America the Beautiful pass to get in, plus a separate wilderness permit for any overnight backcountry camping. Day-use driving on Tioga Road doesn't require an additional permit, but camping outside designated sites without a wilderness permit is a citation.
What's the hardest section of this trail and what should I actually expect?
The roughest stretch is the backcountry spur approaching Glen Aulin — loose granite slabs, embedded rocks, and narrow shelf sections with limited turnout space. It's not technically extreme, but one wrong line on the slab can mean a scraped rocker or a stuck tire with nowhere to go for help.
There's no cell service out here — how far is the nearest gas and how should I plan for emergencies?
Lee Vining is the closest fuel stop, roughly 12 miles from the Tioga Road entrance at Tioga Pass — fill up there, not in Yosemite Valley. Zero cell service means zero calling for a tow; bring a satellite communicator like a Garmin inReach, and let someone know your exit timeline before you leave pavement.
