Yosemite National Park

Yosemite Valley is just 7 square miles — less than 1% of the park — yet it captures most visitors' attention with good reason. El Capitan's 3,000-foot granite face is the largest monolith of exposed granite in the world and a mecca for rock climbers who sometimes spend days on its vertical walls. Half Dome's distinctive shape rises 4,737 feet above the Valley floor, and its cable route to the summit is one of the most sought-after hikes in the national park system (permit required via lottery). Yosemite Falls, the tallest waterfall in North America at 2,425 feet, thunders in spring and early summer before dwindling to a trickle by late August. Bridalveil Fall, Sentinel Falls, and Nevada Falls add to the Valley's dramatic water features, while the Merced River offers peaceful meadow walks in contrast to the towering walls above.

The Tioga Road (open June–October) leads to Tuolumne Meadows at 8,600 feet — the largest subalpine meadow in the Sierra Nevada and a gateway to some of the park's finest hiking. Cathedral Lakes Trail offers a moderate 7-mile round trip to stunning granite-ringed alpine lakes. Lembert Dome provides panoramic views with a moderate scramble. The High Sierra Camps offer a unique hut-to-hut hiking experience through Yosemite's most pristine backcountry, though reservations are extremely competitive. Glacier Point, reached by car or the Four Mile Trail, provides what many consider the finest overlook in any national park — a sweeping panorama of Half Dome, Nevada Falls, and the entire Valley below.

Yosemite's Mariposa Grove protects over 500 mature giant sequoias, including the storied Grizzly Giant (estimated at 1,800–2,000 years old) and the California Tunnel Tree. A free shuttle connects the Mariposa Grove Welcome Center to the grove from spring through fall. The main trail offers a 2-mile round trip past the most famous trees, while a longer 5-mile loop continues to the upper grove and the Wawona Point overlook. Winter visitors can snowshoe or cross-country ski through the silent, snow-draped groves for an unforgettable experience.

Yosemite's popularity demands advance planning. Summer lodging and campground reservations open on a rolling basis and fill within minutes — set alarms for reservation dates on Recreation.gov. The park requires entry reservations from May through September on peak days (check NPS.gov for current dates). Arrive before 9 AM or after 4 PM to avoid the worst parking congestion in the Valley. Spring (April–May) offers thundering waterfalls and wildflower blooms with fewer crowds, while October delivers fall color and quiet trails. Winter transforms the Valley into a snowy wonderland with ice skating and cross-country skiing. The America the Beautiful Pass ($80/year) covers your entrance fee, and parking at the day-use lots fills by 10 AM in summer.
