Every June, I watch the same thing happen. A family pulls into Yosemite Valley at 11 a.m. on a Saturday, spends forty minutes looking for parking, finds a spot at the overflow lot near the stables, walks to Lower Yosemite Fall, takes a photo, and leaves. They drove five hours for ninety minutes in a crowd. They didn't know the waterfalls were already fading. They didn't know the high country was open. They didn't know that two hours north of where they were standing, there were alpine lakes with nobody at them.
June is the month when the Valley is at its most crowded and, in a good year, at its most spectacular. Waterfalls hit their peak. The high country opens. The days are the longest of the year. Everything the park is famous for is happening at once. But with historically low snowpack and no reservation system, this June is shaping up to be the month that separates the visits that work from the ones that don't.
Here is how to be on the right side of that line.
The Sierra Nevada snowpack on April 1, 2026 was measured at roughly 18 percent of average, the second-lowest figure in recorded history. I covered what low snowpack means for the park this year in detail. Snowpack is the bank account that funds Yosemite's waterfalls, and this year the account is nearly empty.
In a normal year, warm June days melt the snowpack and send torrents of water over the Valley's granite walls. Yosemite Falls, Bridalveil Fall, Vernal and Nevada Falls all run at or near their peak. This is not a normal year. With so little snow to melt, the waterfalls peaked early. By late May, flows that would normally build through June were already declining. Yosemite Falls typically peaks in late May and can run strong into mid-June in an average snowpack year. In 2026, expect it to weaken noticeably by mid-June and reduce to a trickle by early July. Bridalveil Fall, which has a smaller watershed, will thin out sooner.
If seeing waterfalls at full power is a priority, the first two weeks of June are your window. After that, you are watching the decline. They will still be worth seeing. But the roaring, mist-soaking experience visitors imagine when they picture Yosemite Falls is a narrow window this year, and it is closing fast.
For waterfall-specific hiking, the Mist Trail is still the best way to experience Vernal and Nevada Falls up close. One complication: the National Park Service has announced weekday closures of the Mist Trail corridor beginning June 30 for a rehabilitation project. If you are visiting in late June or July, plan your Mist Trail hike for a weekend day or go before the closures begin.
Tioga Road opened on May 15, 2026, the earliest opening since 2015. In a typical year, it opens in late May or early June, and sometimes not until July. The low snowpack that is shortchanging the waterfalls gave us something in return: early access to the high country.
This matters more than usual in 2026. With no reservation system managing Valley crowds, the high country is the single best pressure valve available to you. Tuolumne Meadows, Cathedral Lakes, Tenaya Lake, the Dana Fork, Lembert Dome: these places are two hours from the Valley floor and they are a different park entirely. I drove up on the opening weekend and counted eight cars at the Cathedral Lakes trailhead at 9 a.m. on a Saturday. That same morning, the Valley had been full since 7:30. If your trip overlaps with a Valley gridlock day, Tuolumne is the answer.
Cathedral Lakes is the signature Tuolumne day hike and one of the best in the park. The trail to Lower Cathedral Lake is about 3.5 miles one way with roughly 1,000 feet of gain, ending at a granite-rimmed alpine lake beneath Cathedral Peak. In early June it may still have snow patches on the upper trail. Bring traction devices if you are hiking before mid-month.
Tuolumne Meadows Lodge opens June 5. The Tuolumne Meadows Store and Grill opens on the same timeline. This is also prime wildflower season: the meadows should be blooming by mid-June, though the compressed snowmelt may push the peak earlier and shorter than usual.
Entering through Tioga Pass from the east side is also in play now. If you come over the pass from the Eastern Sierra, you can spend a full day in the high country without ever touching the Valley.
Glacier Point Road opened on May 9, another early opening. This gives you access to Glacier Point itself, Sentinel Dome and Taft Point, and the full Glacier Point Road experience.
It also opens the option I recommend to almost every June visitor: hike Four Mile Trail up and Panorama Trail down. This is the single best day hike in Yosemite, and in June you get waterfalls at every turn. Vernal and Nevada Falls are both visible from the Panorama Trail, and Illilouette Fall, which most visitors never see, is at its best in early June. Start by 7 a.m. to beat the heat on the Four Mile ascent.
There is no way to sugarcoat this. June 2026 is shaping up to be the most crowded month in the park in years. The reservation system is gone, and the numbers reflect it. More than 836,000 visits were recorded through late May, roughly 100,000 more than the same period last year. On Memorial Day weekend, Valley parking lots were full by mid-morning and entrance waits exceeded ninety minutes.
I wrote about why the park needs a reservation system. For planning your June trip, here is what you need to know:
Arrive before 7 a.m. On any Friday through Sunday, and especially on holidays, Valley parking lots will fill early. If you arrive at 10 a.m. on a Saturday, you will not find parking at any major trailhead. This is not an exaggeration. I watched it happen every weekend in May.
Park once and use the shuttle. The free Valley shuttle runs every 12 to 22 minutes and stops at every major trailhead, the Visitor Center, Curry Village, and the Ahwahnee. Getting around the Valley without moving your car is a skill worth learning before you arrive.
Visit midweek. Tuesday through Thursday, the park is a fundamentally different place. If you have flexibility, this is the single biggest quality-of-life improvement you can make. If you are still deciding where to stay in or near Yosemite, booking midweek dates also opens up more lodging options.
Go outside the Valley. The Valley floor absorbs roughly 90 percent of Yosemite's visitors. Hetch Hetchy is fifteen minutes from the Big Oak Flat entrance and rarely crowded. Wawona and the Mariposa Grove are on the south end. The Merced Grove has almost no one in it. And with Tioga open, the entire high country is available. Plan at least one full day outside the Valley.
If you arrive in the afternoon, the day is not wasted. The golden hour in Yosemite Valley in June starts around 6:30 p.m. and lasts until sunset around 8:25. Some of the best light and thinnest crowds of the day happen between 6 and 8 p.m.
Bear-related property damage in Yosemite increased 316 percent year over year according to recent park reporting. Drought years make wild food scarcer. When natural berry and nut crops are thin, bears look for alternatives. Your cooler in the back seat is an alternative.
Bear-proof food storage is not optional. Every campsite in the park has a bear box. Use it. Every piece of food, every scented item (toothpaste, sunscreen, lip balm), and every cooler goes in the box when you are not actively holding it. If you are day-hiking, do not leave food visible in your car. Not in a bag. Not under a blanket. Not in the trunk of a sedan, which a bear can pry open in under a minute.
A bear that learns to associate cars with food is a bear that eventually gets killed. I do not say that to be dramatic. I say it because it happens every year in this park, and every year it starts with someone who thought the rules were suggestions.
June in Yosemite Valley means daytime highs typically between 80 and 90 degrees Fahrenheit. The high country runs 15 to 20 degrees cooler. Mornings in the Valley start around 50 to 55 degrees and warm fast.
Your day pack for a June hike needs at minimum two liters of water per person for any hike over four miles, sun protection (the granite reflects everything), and a layer for elevation. If you are spending a full day in the high country, bring a real jacket. Afternoon thunderstorms are possible in Tuolumne by late June, and they move in fast at 8,600 feet.
The Merced River will be swimmable in some sections by mid to late June. In a low snowpack year, it warms up earlier. Check current conditions before wading in. Early June flows can still be fast enough to be dangerous even in a drought year.
June 2026 in Yosemite is a compression event. Low snowpack pushed everything earlier: the waterfalls, the road openings, the wildflower bloom, the bear activity. No reservations pushed everything more crowded. The result is a month where the park is both more accessible and more strained than in recent memory.
If you are visiting in the first two weeks, you will see waterfalls and wildflowers and the high country waking up and the Valley at its most alive. If you are visiting in the last two weeks, the waterfalls will be fading, the Mist Trail may be partially closed, and the heat will be climbing. Both versions of June are worth the trip. But they are different trips, and planning for the one you are actually getting is the difference between a great visit and a frustrating one.
Start with the basics if this is your first time. Plan your trip end to end if you want the full framework.
The people who have the best June trips are not the ones who see the most. They are the ones who showed up knowing what kind of June they were walking into. This year, that matters more than it usually does.
Plan accordingly.
