1. Watch Waterfalls in Yosemite ValleyIf you want to be really wowed by the Yosemite Valley's grandeur, time your visit for late spring. May is usually the month when Yosemite's waterfalls flow most dramatically, thanks to rushing snow melt from high in the Sierra Nevada Mountains. Dozens of waterfalls, both big and small, burst into life along the granite walls of the valley. You can hear them thundering everywhere you walk. Often a cloud of mist obscures the bottom of the fullest falls, meaning that if you walk right up to them, you won't see much. But if you know the right vantage points, you'll be able to capture some unforgettable photos.
2. See Famous Viewpoints in YosemiteThe natural beauty of Yosemite is so incredible that it inspired an entire 19th-century conservation movement, which resulted in the valley's protection as a national park in 1890. Naturalists led by John Muir (1838–1914) and artists like photographer Ansel Adams (1902–1984) found inspiration for their life's work here. First-time visitors to Yosemite National Park won't want to miss any of the following heart-stopping vistas, all easily accessible from paved roads throughout the park.
3. Walk Among Giant Sequoia GrovesStart by taking the whole family on a joyful nature walk through the Mariposa Grove of giant sequoias. Near the southern entrance to Yosemite National Park, this monumental grove shelters over 500 of the world's largest living trees, which tower over human day trippers. Although giant sequoia are not the oldest trees on Earth (those are ancient bristlecone pines, found in the eastern Sierra Nevada), nor are they the planet's tallest trees (those are the coast redwoods, as seen in Northern California), they are still mighty impressive due to their record-breaking size.
4. See Black Bears and Other WildlifeWith more than 400 kinds of animals and multiple life zones for plant life, Yosemite National Park is a top spot for wildlife watching. In fact, it's everywhere you look. The park's protected status, combined with a variety of natural environments that stretch from the Sierra Nevada's wooded foothills to the treeless alpine tundra, provides unmatched habitat for wildlife.
5. Explore Trails While Hiking or Riding a HorseYosemite National Park is crisscrossed by an unmatched network of backcountry trails open to hikers, backpackers, and horse riders. Incredibly, almost 95 percent of the park is designated as wilderness. Whether you just want to just get out of the car and do a little exploring, or you're planning a multi-night backcountry adventure on foot or horseback, we've got just the thing for you and your family. For more trail information, including current conditions, safety, and wilderness permits for overnight trips, visit the park's official website (http://www.nps.gov/yose).
6. Go Camping on Your Yosemite TripNothing beats sleeping under the stars in Yosemite National Park, especially if you're looking for a little family togetherness. Developed campgrounds scattered throughout the park are a perfect place to introduce your kids to the joys of tent camping, or alternatively to park your RV for a few nights or a week.
7. Go Rock Climbing in YosemitePart of what makes the Yosemite Valley unique is its towering granite rock formations. Stalwarts like the giant wall of El Capitan, the polished promontory of Half Dome, and skyscraping Glacier Point all call to expert climbers, who sometimes bivouac overnight while suspended in mid-air. The excitement of rock climbing in Yosemite can be experienced by everyone, whether or not you decide to rope up yourself. Just watching climbers crawl like bugs up the face of big walls or free climb beside Yosemite Falls, North America's tallest waterfall, is thrilling enough.
8. Winter Recreation Abounds in YosemiteVisiting the Yosemite region during winter is an unforgettable experience. Meadows, forests, and Sierra Nevada peaks are all covered in powdery blankets of snow, while the valley becomes a winter wonderland.
9. Explore Yosemite's History & CultureYosemite is the wild, wild West. From its earliest Native American inhabitants, to the mid-19th-century California Gold Rush, and the later arrival of ranchers, loggers, and hoteliers, the land surrounding Yosemite National Park is amazingly rich in historical sites.
10. Attend a Festival or Ranger-Led ActivityYosemite National Park is a four-seasons outdoor destination. You can come to watch waterfalls in spring, go hiking in the Sierra Nevada high country in summer, roast marshmallows over your campfire in fall, and go skiing and snowshoeing in winter. Timing your visit to coincide with one of the region's many festivals will only enhance your Yosemite vacation.
