Is Tioga Road open? Dates & closures.

Is Tioga Road open?

That depends on your date, and the official conditions page below is the place that answers it for today. Tioga Road is the high, seasonal crossing of the Sierra, the continuation of Highway 120 through the park and past Tuolumne Meadows. It is open in summer and fall and closed to cars by snow the rest of the year. The park's Tioga Road page says it "is typically open to vehicles from late May or June until sometime in November," and it opened at 8 a.m. on Friday, May 15 in 2026. Yosemite as a whole, by contrast, is open 24 hours per day, 365 days per year, so a closed Tioga Road does not mean a closed park. It means the high country and the route across the Sierra are shut.

Typical opening and closing windows.

Aim for late May or June for the opening and expect a close sometime in November. Those are the park's own stated norms. The spring end is the unpredictable one. The 2026 opening on May 15 came before that usual window, while the park's historical notes show that in 2019 Tioga Road opened on June 21, with entry limited to two one-hour windows a day until July 1. Five weeks separate those two openings. The park is direct about this, saying that "predicting when these roads will open is not possible, even in late spring, because weather in April and May can affect plowing progress significantly." The fall close depends on snow too, and "sometime in November" is a range, not a date. If your trip is in May or June, treat Tioga as a maybe and have a Valley-based plan. From July into October, the road is normally in its open season.

What drives the dates.

Snowpack and plowing, plus a long checklist after the plows get through. Clearing "begins on or about April 15 each year and usually takes between one and two months." Park crews plow 45.5 miles from Crane Flat to Tioga Pass, while Caltrans plows Highway 120 from Lee Vining up to the Tioga Pass Entrance. An avalanche team works ahead of the plows, especially at Olmsted Point, which the park calls the most dangerous of the avalanche zones. Downed trees and rockfall often need clearing too. Even after the plows punch through, crews have to set up water, restrooms, radio, and trash service before the road can open. A deep snowpack means more of all of that work, which is why the opening date moves so much from year to year.

How crowds ramp as the road opens.

Yosemite's crowd curve is gentler than Glacier's or Rocky Mountain's because the Valley draws visitors all year, so the numbers do not collapse in winter the way a snowed-in mountain park's do. Still, the high-country season is the busy season. July and August are the two peak months, and June already runs about 95 percent of the peak as Tioga opens and the high country comes into play. The five-year average climbs about 1.3x from May to June.

For a calmer high-country drive, October is the better bet. Visits drop to about 77 percent of the peak, and the road is normally still in its open season, though an early storm can change that. See the Yosemite crowd calendar for the full year.

Common questions.

When does Tioga Road open?
Typically late May or June, per the park, which says the date can't be predicted because spring weather sets the plowing pace. In 2026 it opened May 15. In 2019 it opened June 21. Plowing usually begins around April 15 and takes one to two months.

Is Tioga Road open now?
We do not track it live. The park says the road is typically open from late May or June until sometime in November, and closed to cars the rest of the year. For today's status, check the park's conditions page or call 209/372-0200 (press 1 then 1).

When does Tioga Road close?
Sometime in November in a typical year, once snow arrives. After that it stays closed to cars through winter and spring, when the park treats it as open to skiers and snowshoers, until plowing reopens it.

Can you get to Yosemite Valley when Tioga Road is closed?
Yes. Yosemite is open 24 hours a day, 365 days a year. Some roads close for snow from around November through May or June, but a closed Tioga Road does not close the park or the Valley.

How we read the crowds

The monthly visit counts come from the official NPS Visitor Use Statistics. "5-yr avg" is the mean of 2021 through 2025 recreation visits for that month. "Share of peak" compares a month against the park's own busiest month, so 100 percent marks the single busiest month of the year. The road opening and closing windows are not in that data. Those come from the park's own official road pages, which we read on September 13, 2026, and they shift with snow and weather every year, so we hedge them on purpose. This is an independent site, not affiliated with the National Park Service, and it carries no live alerts.
