Best California National Parks in Summer

Redwood National and State Parks

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.

Visitors to Redwood will find massive redwoods, 37 miles of gorgeous California coastline, open prairie lands, and two major rivers. For thousands of years American Indian tribes have made a home within the North Coast region; today they still maintain a cultural presence in the areas surrounding the (RNSP) Redwood National and State Parks.

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.

Yosemite National Park

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.

Nearly 1200 square miles, Yosemite National Park offers more than giant sequoias. It’s home to the iconic granite peaks of El Capitan and Half Dome, stunning vista views from lookout landmarks like Tunnel View, and the unforgettable and massive 2,425ft Yosemite Falls.

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.

Summer here is the best time to enjoy the campgrounds and hiking trails. The temperature is usually warm during the day, and chilly at night. Average summer temps in Yosemite are in the high 80s but can drop quickly. Wear long layers for both sun protection and warmth.

Sequoia and Kings Canyon National Park

A consolidation of management for Sequoia and Kings Canyon National Park in 1943 gave us two parks in one. 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.

Lassen Volcanic National Park

Less than an hour from Redding, California in the states northeast corner, rests the often-overlooked Lassen Volcanic National Park. Lassen is a beautiful national park complete with steaming fumaroles, lush meadows, jagged peaks, clear mountain lakes, volcanoes, and numerous hydrothermal areas. As one of the lesser-known National Parks it’s usually the least crowded.

Lassen offers plenty to see and do. Boardwalk trails show off popular areas in the park such as Devil’s Kitchen and Bumpass Hell but that’s not all. Visitors can enjoy hiking over 150 miles of trails.

Fishing, camping, or swimming at Manzanita Lake. Make the climb up Lassen Peak for spectacular views or enjoy other activities like mountain bike or horseback riding. Lassen Volcanic National Park offers surprises at every turn, including a cold boiling lake and gorgeous cascades.

Summer is a great time visit as you gain access to all the park areas, trails, and activities along with special summer events. Visitors can expect warm temps in the daytime, and cool temps in the evening. The average high in the summer is 70s to 80s and lows in the low 50s. For every 1000ft increase in elevation expect a 5 degree decrease in temperatures.

Channel Islands National Park

A chain of five islands off the Southern California coast, Channel Islands National Park is only accessible via boat, sea plane, or ferry. A remote natural environment with no services or amenities, visitors need to come prepared with everything they need. Popular activities include dolphin or whale watching, hiking, picnicking, kayaking and more.

Each of the Channel Islands offer something unique you’ll want to see. Anacapa Island has trails leading to a 1932 lighthouse and the clifftop Inspiration Point. Santa Rose Island is home to the rare Torrey pines.

Santa Cruz Island has many sea caves including the notable Painted Cave. The southernmost Santa Barbara Island attracts nesting seabirds while thousands of seals gather at San Miguel Island’s Point Bennett.

Summer time at Channel Islands is peak season and the best time of year to visit and enjoy sailing, kayaking, diving, snorkeling, and swimming. In the Summer, the parks underwater video program begins at Anacapa and the mainland visitor center broadcasts live. Average temperatures are in the 60s and 70s and are typically moderated by the moist ocean air. Nighttime especially has high humidity and frequent fog.
