10 Best U.S. National Parks to Visit In the Summer

Most of us associate summer with some form of camping or outdoor recreation. But not all national parks are great summer destinations. Many parks in the Sun Belt, for example, experience sweltering temperatures. So if you want to check off a few destinations on your national parks bucket list this year, you’ll need to focus on the best national parks to visit in the summer in the U.S. 

As a general tip, many U.S. parks experience the height of visitation during the summer months. You’ll need to plan ahead to secure campsite reservations, book guided tours and research safety tips for the activities you want to do once you reach your destination. 

Because national park campgrounds fill up quickly, consider campgrounds outside the park too. Park campgrounds can also get expensive, and because they see such high visitation, keeping up with maintenance can be tough for park staff, especially toward the end of the camping season. 

Good Sam Parks provide an affordable alternative to camping inside the parks during peak season. Good Sam members can save big with a 10 percent discount at any of our 2,000-plus Good Sam Parks across North America.

The 10 Best U.S. National Parks To Visit in the Summer

That being said, your journey begins with a simple decision: deciding which park to visit and planning your national parks road trip! So here are a few of the best U.S. national parks for summer trips: 

Crater Lake National Park

It’s honestly hard to find a more iconic park than Crater Lake. The lake’s caldera is one of America’s most picturesque natural features. Visiting this park during the summer provides the best chance to experience everything that Crater Lake has to offer. 

RV sites are available in Mazama Campground, and the Rim Drive is accessible to most RVs and travel trailers, even if it has speed restrictions. There’s also no shortage of hiking trails, fishing opportunities and guided tours to check out during your visit.

Glacier National Park

Because it’s one of the northernmost parks in the contiguous U.S., summer is the only time when the park’s higher elevations are accessible. Glacier National Park is a hiker’s paradise, and many hikes come with the chance to cool off in a crisp alpine lake. 

The park’s Going-to-the-Sun Road is one of the most iconic scenic drives you’ll find in any national park. In addition, you’ll find views of some of the few remaining glaciers in the lower 48 states in this mind-blowing park.

Sequoia and Kings Canyon National Parks

When folks are flocking to the valleys and waterfalls in Yosemite National Park, you can find a much quieter experience in nearby Sequoia and Kings Canyon National Parks. These neighboring parks are often overlooked, so they’re a great option if you’re looking to beat the summer crowds. 

One of the coolest attractions in these parks is the General Grant Tree. Standing at a height of roughly 270 feet and with an estimated circumference of 107 feet, this sequoia is the second-largest tree in the world (and it’s over 3,000 years old!).

At more than 100 feet tall, Ramsey Cascades is the tallest waterfall in the park. But some of the other notable falls you should explore include Grotto, Laurel, Abrams, and Rainbow Falls. Early summer is also a great time for wildflower viewing in the Smoky Mountains.

Don’t let their cozy name confuse you, though. This Alaskan wilderness is harsh in the winter but incredibly lovely during the summer. Visitors to this park in southeastern Alaska can experience everything from walking beaches at low tide to scrambling up rugged mountainsides at higher elevations.

Situated along the Lonely Highway (U.S. 50), the park is a stop for anyone seeking a unique road trip through Nevada’s many mountain ranges. 

The park includes peaks above 13,000 feet in elevation, 5,000-year-old bristlecone pines, and more than 40 caves. The arid region along the Nevada-Utah border might not be the place you’d expect to find a glacier, but that’s exactly the case if you visit this national park.
