Titus Canyon is where visitors can enjoy multicolored rocks and a ghost town.
Darwin Falls is a remarkable sight to behold in the middle of the Mojave Desert, while the winding pine trails up Telescope Peak result in breathtaking views of the valley below.
Needless to say but Death Valley is one of the best places to visit in California and an easy day trip from Las Vegas!
Hiking and backpacking are popular ways to explore the arid surroundings, with Natural Bridge, Golden Canyon, and the Ubehebe Crater Rim Hike standing out.
The famous Zabriskie and Dantes Valley Viewpoints are the spots that give you the panoramic views of Mesquite Sand Dunes (watch out for the rattlesnakes) and the spiky salt mounds of Devil’s Golf Course.
The best time to visit the strikingly arid Death Valley National park is springtime, when the wildflowers turn Death Valley into a colorful paradise.
2. Lassen Volcanic National Park, California
Lassen Volcanic National Park, situated in northern California (one of the most beautiful US states), is known for its wildflower meadows, volcanoes, and pristine mountain lakes.
Lassen Peak Volcano is the largest plug dome volcano in the world and offers the best view from its summit.

Popular hikes in the area include Devil’s Kitchen and Terminal Geyser.
The best time to visit is from June to October, while the safest months are August to September. All of the access roads are closed from December to May.

This West Coast national park is an essential cog in the Mojave Desert ecosystem, providing a habitat for many mammals, birds, lizards, and insects.
It’s a monzogranite climbing heaven with many rock climbers, highliners, and boulderers flocking here to test their skills against the slabs, cracks, and steep climbing terrain.
Skull Rock, Heart Rock, and Arch Rock are the formations that stand out in Joshua Tree, with a Barker Dam hike taking to Cholla Cactus Garden.
The panoramic Key Views look out over the impressive Coachella Valley, where hiking trails bob and weave through Hidden Valley’s boulders.

4. Olympic National Park, Washington
Olympic National Park is, without a doubt, the most diverse of all the West Coast national parks, and it turns out it is a short trip from Seattle.
Visitors can expect several different ecosystems in this million-acres vastly varied landscape, from glacier mountain ranges, ancient rain forests, large lowland lakes, and over 70 miles of wilderness coastline.
Climbers enjoy the challenge of Mt. Olympus, Mt. Deception, and Mt. Constance, all of which has summits close to 8,000 ft.
Hiking through the diverse ecosystem is a popular way to explore the park; hikes that stand out are Sol Duc Falls (1.6 miles of trail) and the more challenging Klahhane Ridge Trail (6.8 miles) leading to Lake Angeles.

5. Pinnacles National Park, California
Pinnacles National Park might not be as famous as other West Coast national parks due to being the newest (designated in 2013) and relatively small (26,685 acres).
However, you can experience exciting caves, stunning rock formations formed millions of years ago, and a chance to spot the elusive California Condor.
All of that is just two hours south of San Francisco, one of the most beautiful cities in the US.
You could even combine this visit with a Big Sur road trip. Big Sur is a scenic drive in California that can be as short or as long as your want (check out more West Coast road trips here).
Anyway, with only 30 miles of hiking trails, visitors explore this park in a day or two.
The moderate Condor Gulch Trail is an easy way to view the valley, with the High Peak trails taking you around gigantic rock formations, which the park is known for.
Bear Gulch Cave is open to exploring for ten months of the year so as not to disturb Townsend’s big-eared bats, who rest in the caves during winter.
If you don’t get to see the endangered California Condor, hopefully, you get a sight of the turkey vultures, golden eagles, hawks, and kangaroo bats.
The best time to visit the fairly new Pinnacles National Park is when the temperatures are mild, typically in spring and fall, with wildflowers blooming between March and May.

Channel Islands National Park might be the most challenging national park to visit of all the national parks on the West Coast, as it’s not situated on the land.
This national park is five beautifully preserved islands on the coast of Santa Barbara. A car won’t get you here; you can only reach these special islands by boat or plane.
Isolation from the mainland USA has led to the infestation of unique plant and animal life, like the fantastic island fox and island scrub jay.
