Half Dome and El Capitan rise majestically from the valley floor, while Yosemite Falls—North America’s tallest waterfall at 2,425 feet—creates a mesmerizing spectacle, especially during spring runoff. Don’t miss Glacier Point for panoramic valley views or the ancient giants in Mariposa Grove, home to over 500 mature sequoias including the Grizzly Giant, estimated to be 1,800 years old.

Best Hiking Trails

• Mist Trail to Vernal and Nevada Falls (Moderate to Strenuous, 7 miles round-trip) – Experience the refreshing mist as you climb alongside these powerful waterfalls.

• Four Mile Trail (Strenuous, 9.6 miles round-trip) – Challenging switchbacks reward hikers with breathtaking views from Glacier Point.

Ideal Visiting Seasons

Spring (April-May) showcases Yosemite’s waterfalls at peak flow, creating spectacular displays as snowmelt cascades down granite cliffs. Fall (September-October) offers pleasant temperatures and fewer crowds, with beautiful golden foliage adding warmth to the landscape.

The South Rim offers the most accessible viewpoints, including Mather Point and Yavapai Observation Station, where the canyon’s layered geology tells Earth’s 2-billion-year history. The North Rim, standing 1,000 feet higher, provides a more secluded experience with spectacular vistas from Bright Angel Point and Cape Royal, where you can see the Colorado River winding through the canyon’s depths.
