60 miles long, along the Northern California Coastline, almost at the Oregon border, sits Redwood National and State Parks. This national park, along with the three redwood state parks, consists of protected forests and beaches, and are home to some of the oldest and tallest trees in the world.

Redwoods is an absolute must visit in the summer; it’s the coolest of the national parks because of its proximity to the coast.

Visitors should expect cooler, damp weather. Year-round temperatures fall between the mid-40s to mid-60s, and summer can be foggy with highs in the low-70s.

Best known for its waterfalls and giant sequoia trees, Yosemite National Park rests in Central California’s Sierra Nevada Mountains and attracts over 400 million visitors every year from around the world.

History, hiking, and wildlife watching are common in the National Park, and Tuolumne Meadows is the perfect spot for it all. Tuolumne follows the banks of the Tuolumne River and hikers have the opportunity to cross paths with the famous Pacific Crest Trail.

The parks sit side by side in the southern Sierra Nevada, east of the San Joaquin Valley, and are part of the Sequoia National Forest. Combined, Sequoia and Kings Canyon National Park is an impressive 1,353 square miles.

Home to the world’s oldest known sequoia and largest trees, this “forest of giants” gives us a beautiful and accessible forest environment complete with crystal clear waterfalls, rivers, and creeks.

The parks caverns are extraordinary, and visitors here can take a guided tour through the unique marble caves. The landscape is diverse with dramatic Sierra Mountain scenery, granite domes, rushing rivers, deep canyons, rugged foothills, huge mountains, and more.

Sequoia is generally more crowded than King’s Canyon, but both are stunning and have something to offer.

The best time to visit Sequoia and Kings Canyon National Park is in Summer, June through August, when weather is the most stable. However, weather can be quite different and change quickly between differing park areas. The weather varies 20 to 30 degrees as you change elevation. It’s entirely possible to have spring blooms in the foothills and at the same time have snow at Giant Forest.
