Yosemite Valley is seven miles long and half a mile wide, hemmed in by granite walls that rise nearly a vertical mile on both sides, and it contains some of the most celebrated natural scenery on the planet. El Capitan’s 3,000-foot vertical face on the north wall; Half Dome’s sheared-off granite dome at the valley’s eastern end; Yosemite Falls dropping 2,425 feet in two stages from the north rim — the Valley itself can feel slightly unreal, like someone assembled the greatest hits of American wilderness into a single small space. More than four million visitors a year come to see it, which means that how you approach your visit matters enormously.

The Reservation System and When to Go

Yosemite requires advance reservations during peak season — typically from late April through early October, the park uses a day-use reservation system for vehicles entering the Valley. These reservations sell out weeks in advance and are available through Recreation.gov at 8:00 a.m. Pacific time. If you can’t secure a day-use reservation, the park is still accessible via tour buses from Merced, YARTS bus service from gateway communities, or by staying inside the park at a campground or lodge (which grants vehicle access for the duration of your stay).

Shoulder season — October through November and March through April — offers meaningful advantages. The Valley is less crowded, waterfalls are strong from snowmelt or fall rains, and the morning light on the granite walls in autumn is particularly beautiful. Winter (December–February) brings its own magic — snow-dusted meadows, Half Dome reflected in a frozen Merced River — with no reservation requirement and a fraction of the summer crowds.

Yosemite Valley: The Classics

The Valley Floor Trail offers a mostly flat, paved loop that connects all the major viewpoints — El Capitan Meadow, Valley View, Bridalveil Fall, Valley View, and Sentinel Bridge, where the iconic Half Dome reflection in the Merced River is best photographed at dawn. Plan to spend at minimum a full day walking or cycling this loop; the free Valley shuttle makes it easy to break the route into sections.

Yosemite Falls is a short walk from Yosemite Village and flows most powerfully from March through May, fed by snowmelt from the high country. By late summer it often slows to a trickle or disappears entirely. The lower fall is accessible via a brief paved path; the upper fall requires a serious 7-mile round trip hike with 2,700 feet of gain.

Bridalveil Fall, visible from the Valley floor and accessible via a short paved trail, flows year-round and is often backlit by afternoon light in a way that produces a characteristic wind-carried spray — hence the name.

Half Dome: The Permit-Required Summit

Reaching the top of Half Dome requires a permit obtained through a lottery system administered by the NPS. The regular season lottery opens in late March for permits covering the period from late May through mid-October; a smaller daily lottery for the same day or next day is also available. The hike is 14–16 miles round trip with roughly 4,800 feet of elevation gain, including the famous cable section on the final approach to the summit where vertical steel cables assist climbers up the 45-degree granite slope.

Half Dome is serious hiking territory — cramped ledges, exposure, and the cable section demand respect even from experienced hikers. Check the NPS Half Dome permit information for current lottery dates and requirements.

Tuolumne Meadows and the High Country

Tioga Road (Highway 120) climbs from the Valley to over 9,900 feet, crossing the Sierra Nevada crest and passing through Tuolumne Meadows — a high-altitude subalpine meadow that feels like a completely different park from the Valley below. The meadows open for the summer season typically in late May or June depending on snowpack and close when the first major storms arrive in fall.

This is backcountry Yosemite: granite domes, glacial tarns, and high-elevation hiking trails that see far fewer people than the Valley. The John Muir Trail passes through Tuolumne, and backcountry permits for overnight trips in the high country are available through a reservation system. Lembert Dome and Pothole Dome are excellent short hikes accessible directly from the Tuolumne Meadows area.

Practical Tips for a Successful Visit

The park has strong cell phone coverage in some areas and none in others — download the Yosemite NPS app with offline maps before arriving. Parking in the Valley is genuinely limited; the shuttle system is faster and less stressful than driving. Bring bear canisters if camping — food storage regulations are strictly enforced throughout the park.

For California natural area trip planning, explore the Park Guides section — nearby Northern California parks including Lassen Volcanic National Park and Muir Woods National Monument make natural additions to a California wilderness itinerary.

FAQ

Do I need a reservation to enter Yosemite? During peak season (typically late April through early October), day-use vehicles entering Yosemite Valley require advance reservations purchased through Recreation.gov. Visitors arriving by YARTS bus or staying overnight at park facilities are not subject to the day-use requirement.

When do Yosemite’s waterfalls peak? Waterfalls are at their most powerful from late March through May, fed by snowmelt from the high country. Yosemite Falls, Bridalveil Fall, and Nevada Fall are all spectacular during this window. Most high-elevation falls slow or dry up by August.

How do I get a Half Dome permit? Half Dome day hike permits are allocated through a preseason lottery (opens late March) and a daily lottery. Apply through Recreation.gov. Competition is intense; apply for multiple dates to improve your odds.

What’s the best base for a Yosemite visit? Staying inside the park at any of the lodges or campgrounds gives you morning and evening access before the day-use crowds arrive. Outside the park, the gateway towns of El Portal, Groveland, Mariposa, and Lee Vining (Tioga Road side) all offer lodging.

Is Yosemite worth visiting in winter? Yes, especially for visitors who have already seen the Valley in peak season. Winter brings smaller crowds, no reservation requirements, and snow-dusted scenery that’s genuinely beautiful. Valley roads remain open year-round; Tioga Road closes in winter.
