America's most iconic national park with El Capitan, Half Dome, and Yosemite Falls
Yosemite National Park occupies 750,000 acres of California's Sierra Nevada mountain range and draws nearly four million visitors annually to its glacier-carved valley, ancient granite monoliths, and towering waterfalls. The park's centerpiece, Yosemite Valley, stretches seven miles between sheer granite walls that rise more than 3,000 feet, with El Capitan on the north side — the largest exposed granite face on Earth — and the curved profile of Half Dome to the east. Yosemite Falls, the tallest waterfall in North America at 2,425 feet, flows most powerfully in late spring when snowmelt surges through its upper and lower tiers. Visitors who spend at least two days can explore far beyond the valley floor. The Mariposa Grove shelters over 500 mature giant sequoias, including the Grizzly Giant estimated to be more than 1,800 years old. Glacier Point, reachable by road from late May through November, delivers a direct vertical perspective over the valley 3,200 feet below and an unobstructed view of Half Dome. The Tuolumne Meadows subalpine plateau at 8,600 feet offers a quieter, high-country alternative with hiking through granite domes and wildflower meadows. Photography is best pursued from Valley View near the western end of the valley at dawn, from the Tunnel View pull-out for the classic panorama including El Capitan, Half Dome, and Bridalveil Fall, and from Mirror Lake before 9 a.m. when the water reflects Half Dome most crisply. The Mist Trail to Vernal Fall and Nevada Fall involves significant crowds on summer weekends but the granite staircase ascent next to the cascades is rewarding. A timed-entry reservation system applies from late spring through early autumn: visitors arriving between 5 a.m. and 4 p.m. without reservations are turned away at the entrance. Camping and lodging book out months in advance. The free Yosemite Valley Shuttle Bus connects campgrounds, trailheads, and visitor facilities, making it practical to leave a car in a day-use lot and explore without driving.

Tips for visiting
- Book timed-entry reservations months ahead via recreation.gov; the system activates from late spring through early autumn and the park turns vehicles away without them.
- Arrive at Valley View or Tunnel View before sunrise to photograph El Capitan and Half Dome in golden light with minimal pedestrian traffic.
- Use the free Yosemite Valley Shuttle Bus to reach Mirror Lake, Yosemite Falls trailhead, and Curry Village without competing for scarce day-use parking.
- Yosemite Falls typically runs dry by August; visit between April and early June to see it at full volume.
- Glacier Point Road usually opens in late May — check the NPS website before planning a spring visit.
- Use bear boxes at campgrounds and never leave food in a vehicle; bear break-ins are common throughout the valley.
When to visit
Late April through early June offers peak waterfall flow and mild temperatures before summer crowds build. September and October bring fewer visitors, comfortable weather, and autumn color in the valley.
Accessibility
Yosemite Valley's main paths and boardwalks are paved and accessible to wheelchair users. The Yosemite Valley Shuttle Bus runs wheelchair-accessible vehicles on all routes. Cook's Meadow Loop and the Valley View overlook are accessible; most backcountry trails involve steep or uneven terrain.

Frequently asked questions
How long should visitors spend at Yosemite National Park?
Two to three days allows time to walk the valley floor, visit Mariposa Grove, and reach Glacier Point. A single day covers the main valley overlooks and Yosemite Falls but leaves little room for anything else.
Is a timed-entry reservation required to enter Yosemite?
Yes, from late spring through early autumn the park requires a timed-entry reservation for vehicles arriving between 5 a.m. and 4 p.m. Reservations are released on a rolling basis through recreation.gov and sell out quickly.
Is photography allowed in Yosemite?
Personal photography is permitted throughout the park without restriction. Commercial photography and film shoots require a permit. Drone use is prohibited within park boundaries.
Is Yosemite suitable for families with young children?
Yes. The Junior Ranger program engages children of all ages, and the valley floor is largely flat and stroller-accessible. The Mist Trail involves steep uneven stairs and is better suited to older children and adults.
