Taking a summer vacation with the kids to a U.S. national park is one of the most popular family vacation ideas for many Americans. The summer months of late May, June, July, August, and early September are peak travel times, though—and peak times mean the peak crowds. With that in mind, the best national parks to visit in summer are either off-the-beaten-path gems or parks that are so spectacular (and spacious) that they’re worth battling the crowds.
Best National Parks to Visit in Summer with Kids
While there’s never a wrong season for visiting any of the best U.S. national parks, here are the national parks that stand out as particularly worthwhile for a visit during the high temperature and high visitation levels of the summer travel season.

2. Grand Canyon National Park, North Rim
Every summer, the South Rim of the Grand Canyon packs in tourists like Disneyland’s Main Street U.S.A. But the harder-to-reach North Rim is only open seasonally, May through October, and it’s much more manageable in terms of crowds. Only 10 percent of Grand Canyon visitors make their way to the North Rim, which is great news for families looking to visit one of the country’s best national parks in the summer.

3. San Juan National Historic Site
Take a trip 500 years back in time at Puerto Rico’s San Juan National Historic Site, settled by Europeans in the 1500s. The famed Castillo San Felipe del Morro (a.k.a., “El Morro”), a stone fort built by the Spanish, guards the entrance to the Bay of San Juan from its 140-foot-high perch. Consisting of six-levels, the “unconquerable” El Morro was used by troops up until World War II. In 1983, El Morro was designated a UNESCO World Heritage Site.

5. Zion National Park, Kolob Canyons
No doubt about it, Zion National Park is busy. Parking lots are full by 9:00 a.m., and crowds are extreme around the holidays with queues for the canyon shuttle stretching to multiple-hour waits. However, 40 miles northwest of Zion’s narrow slot canyon is the Kolob Canyons district of Zion National Park. Kolob Canyons do not receive near the crowds as Zion Canyon, which makes it one of the great alternative national parks to visit in summer.

Kolob sits 2,000 feet higher in elevation, too, making it typically 10 degrees cooler than Zion. Here families will find brightly colored red rock walls with multiple parallel “finger” canyons. Each of these finger canyons is like a miniature Zion Canyon, broad at its mouth and narrowing to a deep slot at the upper end. Hiking in Kolob Canyons offers the kind of peaceful solitude that’s difficult to find in Zion.
Where to Stay Near Zion’s Kolob Canyons District
The St. George/Hurricane KOA is located 20 miles south on I-15 from the Kolob Canyons Visitor Center. It’s also about 30 miles west of the main Zion National Park entrance in Springdale, Utah.

The one-mile Daemonelix Trail reveals original fossil exhibits of creatures that lived in the Miocene (about 23 million to five million years), and the 2.7-mile wheelchair-accessible paved Fossil Hills Trail takes you to historic dig sites where you walk the same ground that paleontologists walked when they found the Miocene-age bonebed. In the summer, you can also check out two teepees raised by members of the Lakota tribe along the Fossil Hills Trail.
In addition to exploring the trails, several learning experiences are available for families. The “Touching Table” in the visitor’s center is full of things to be held, examined, and identified. Junior Ranger and Peewee Ranger programs are also a great way to turn a vacation or weekend getaway to into an enriching and educational experience.
