Is Yosemite National Park Open Today? 2026 Guide

Last updated: September 6, 2026

If you’re planning a trip to Yosemite National Park and wondering “Is Yosemite National Park open today?”, the answer is yes. According to the latest National Park Service (NPS) conditions update dated September 4, 2026, Yosemite is open, with the main roads into Yosemite Valley and several major park roads currently open.

Yosemite is generally an open year-round national park, but individual roads, trails, campgrounds, and facilities can have seasonal closures or temporary restrictions.

Is Yosemite National Park Open Today?

Yes, Yosemite National Park is open today, September 6, 2026.

The National Park Service states that Yosemite is open 24 hours a day, 365 days a year. However, being open does not necessarily mean every road, trail, campground, or attraction is available at all times. Seasonal conditions, construction, wildfires, snow, rockfall, and other hazards can result in temporary closures.

The latest NPS conditions information currently lists these major roads as open:

• Wawona Road (Highway 41): Open
• El Portal Road (Highway 140): Open
• Big Oak Flat Road (Highway 120): Open
• Yosemite Valley roads: Open
• Tioga Road: Open
• Glacier Point Road: Open
• Hetch Hetchy Road: Open during specified daylight conditions

The NPS recommends calling 209-372-0200 for the most up-to-date road conditions because the online page may not reflect short-term closures.

Is Yosemite Open 24 Hours?

Yes. Yosemite National Park itself is open 24 hours per day, 365 days per year. However, the Hetch Hetchy area follows different access hours and is generally open to day visitors from sunrise to sunset.

This means you don’t need to wait for a park-wide opening time to enter Yosemite. Instead, you should check the status of the particular entrance, road, trail, or facility you plan to use.

Does Yosemite Require a Reservation in 2026?

One of the biggest changes for visitors in 2026 is that Yosemite does not require an entrance reservation or timed vehicle reservation.

The NPS announced that Yosemite would not use its timed-entry reservation system in 2026.

The park’s current reservation information confirms that a reservation is not required to enter Yosemite in 2026.

However, you may still need reservations or permits for specific activities.

For example:

• Camping may require a campground reservation.
• Overnight wilderness trips require a wilderness permit.
• A permit is required to hike to the top of Half Dome when the cables are up.

So, no entrance reservation doesn’t mean no reservations are ever needed in Yosemite.

Are Yosemite Roads Open Today?

As of the latest NPS conditions update, the major roads serving Yosemite are open.

Tioga Road

Tioga Road is currently open.

This is important for visitors traveling across the Sierra Nevada from the eastern side of Yosemite. Tioga Road typically closes during winter because of snow and normally operates only during the warmer months. In 2026, the road opened to vehicles on May 15.

Glacier Point Road

Glacier Point Road is currently open, according to the latest NPS conditions information.

Yosemite Valley Roads

The roads within Yosemite Valley are also currently listed as open.

Even when a road is officially open, visitors should check conditions shortly before driving because conditions can change due to weather, fire activity, accidents, or other emergencies.

Are Yosemite Trails Open Today?

Many Yosemite trails are currently open, but trail conditions vary by location.

The NPS warns that trails can close because of rockfall, snow, ice, fire, or other hazards. An officially open trail can also still contain hazards, so visitors should evaluate conditions before starting a hike.

For September 2026, the NPS currently reports:

• Half Dome cables are up for the season
• A permit is required to hike to the top of Half Dome while the cables are up.
• There are no current closures listed in the Crane Flat–Tuolumne Meadows area.
• No current closures are listed for Mariposa Grove.
• No current closures are listed for the Hetch Hetchy area.

Mist Trail Conditions

The Mist Trail has special seasonal arrangements in 2026.

According to the NPS, through October, the section from the John Muir Trail junction above the Vernal Fall footbridge to the top of Vernal Fall is generally open Fridays through Sundays and holidays. On some weekdays it is normally open from approximately 3:30 p.m. to 7 a.m., when conditions are safe.

Always check the current trail conditions before hiking.

What Is Open in Yosemite in September 2026?

September is generally a good month for accessing many areas of Yosemite because major seasonal roads are typically open.

Based on the latest NPS information, visitors can currently access:

The current conditions page notes that Yosemite Falls is effectively dry, while Vernal Fall, Nevada Fall, and Bridalveil Fall are currently low.

Is Yosemite National Park Open in September?

Yes. September is one of the months when Yosemite is generally widely accessible.

Unlike some parks that have a defined operating season, Yosemite remains open year-round. September falls within the warmer season when several high-elevation roads and facilities are generally accessible.

However, individual facilities can have different seasonal schedules. For example, the Tuolumne Meadows Visitor Center operates approximately from late May through late September, with its exact schedule subject to change.

Is Yosemite Busy in September?

Yosemite can still be busy in September, particularly around Yosemite Valley and popular viewpoints.

Even though there is no timed vehicle reservation requirement in 2026, visitors should not assume that the absence of reservations means there will be unlimited parking or no traffic.

The NPS continues to use traffic-management strategies based on conditions in the park.

If you’re visiting on a weekend, arriving earlier in the day can make it easier to find parking and enjoy popular areas before they become crowded.

Yosemite Weather and Smoke Conditions

September can bring warm, dry conditions to Yosemite, but visitors should also pay attention to wildfire smoke and air quality.

The NPS notes that smoke and ozone can affect Yosemite’s air quality during summer and fall. Smoke can reduce visibility and may affect outdoor recreation.

The current Yosemite conditions page also warns that smoky or hazy conditions are possible because of fires elsewhere in the region or prescribed fire activity within Yosemite.

Before leaving for the park, check:

1. Current road conditions
2. Fire restrictions
3. Fire and smoke information
4. Air quality
5. Weather forecast
6. Trail conditions

Are Campgrounds Open in Yosemite?

Several Yosemite campgrounds are currently open, but campground availability varies by location and date.

The latest NPS conditions information lists Upper Pines, Lower Pines, North Pines, and Camp 4 as open in Yosemite Valley, with reservations required for the listed reservation campgrounds.

Outside Yosemite Valley, the NPS currently lists several campgrounds as open, including:

• Wawona
• Hodgdon Meadow
• Crane Flat
• Tamarack Flat
• White Wolf
• Yosemite Creek
• Porcupine Flat
• Tuolumne Meadows

Some campgrounds have seasonal closing dates, so check the current campground information before making travel plans.

Remember that camping or sleeping in a vehicle is only permitted in a registered campsite where camping is allowed.

Do You Need a Permit to Visit Yosemite?

For ordinary day visits, you do not need an entrance reservation in 2026.

However, certain activities require permits.

Half Dome Permit

A permit is required to hike to the top of Half Dome when the cables are installed. The cables are currently up for the 2026 season.

Wilderness Permit

If you plan an overnight backpacking trip in the Yosemite Wilderness, you need a wilderness permit. The NPS states that wilderness permits are required year-round for overnight stays in the wilderness.

What Time Does Yosemite Open?

Yosemite doesn’t have a standard daily opening time because the park is open 24 hours a day.

However, individual facilities and areas have their own hours.

For example, Hetch Hetchy is generally accessible to day visitors from sunrise to sunset, while visitor centers and other facilities operate on their own schedules.

Therefore, if you’re planning an early-morning or late-night visit, check the specific area you intend to visit rather than relying on general park hours.

How to Check if Yosemite Is Open Before You Go

The most useful things to check are:

1. Current conditions: Look for road, trail, fire, and weather alerts.

2. Road status: Check whether the route you’re using is open.

3. Yosemite webcams: These can provide a useful visual check of current conditions.

4. Fire and smoke information: Particularly important during summer and fall.
