- I’ve been to all 63 major US national parks. There are 5 I always tell people to visit in the summer. (businessinsider.com)
After exploring all 63 major U.S. national parks, I’ve come to appreciate that while each season offers unique experiences, several parks truly stand out during the summer months.
Summer, with its longer days and milder weather, often provides better access to many parks that can be challenging to visit during colder seasons. Although increased visitor numbers are common at iconic sites, the benefits-such as vibrant wildlife activity and easier trail conditions-make summer an excellent time to explore.
Here are five national parks I recommend visiting in summer:
Kenai Fjords National Park, Alaska
Kenai Fjords boasts some of the most stunning and dramatic landscapes in the country.
Access by car is limited to Exit Glacier Road, which typically closes from late October through mid-May due to snow. Summer’s accessibility, warmer temperatures, and extended daylight hours create ideal conditions for visiting this bucket-list destination.
Since much of the park is accessible only by water, I suggest taking a boat tour or kayaking with local operators to fully experience its beauty.
Isle Royale National Park, Michigan
Located in the middle of Lake Superior, Isle Royale is remote and subject to harsh weather, so it’s open seasonally from mid-April to the end of October.
Access is limited to seaplane or ferry, with ferry service becoming less reliable after early September. For these reasons, summer is the optimal time to visit.
While there, hiking to the Minong Ridge and Grace Creek overlooks offers breathtaking views.
Denali National Park, Alaska
Home to Mount McKinley (Denali), the highest peak in North America at 20,310 feet, this park is a must-see.
Although Denali is open year-round, several roads, campgrounds, visitor centers, and transportation services close outside the summer season. A summer bus tour along Denali Park Road provides spectacular wildlife viewing and panoramic vistas, making it the best time for a visit.
Glacier National Park, Montana
Famous for its dramatic mountain scenery and the iconic Going-To-The-Sun Road, Glacier is best experienced in summer.
Heavy snow keeps parts of this roughly 50-mile road closed until late June, so visiting later in the season allows full access. Warmer weather also invites visitors to enjoy a refreshing swim in one of the park’s pristine mountain lakes, with long daylight hours perfect for exploration.
Grand Teton National Park, Wyoming
My personal favorite, Grand Teton is a year-round destination, but summer offers the best conditions for hiking, boating, and swimming.
The park’s jagged peaks and numerous lakes come alive in the warmer months. I recommend a scenic boat ride on Jenny Lake, hiking the Taggart Lake trail, and relaxing at Colter Bay Swim Beach.
Note that the scenic Teton Park Road, which grants access to many key areas, operates seasonally from May through October.
In summary, while U.S. national parks have something to offer any time of year, these five stand out as particularly rewarding summer destinations thanks to their accessibility, weather, and range of activities.
