Grand Teton National Park in Wyoming is my favorite national park in any season, but I think summer is the best time to visit.
The park is known for its jagged peaks and ample lakes, which become perfect for hiking, boating, and even swimming in the warmer summer months.
I love taking a scenic boat ride on Jenny Lake, hiking the Taggart Lake trail (parts of which are currently under construction), and swimming or picnicking at Colter Bay Swim Beach.
Like others on this list, the park is open year-round, but the incredibly scenic Teton Park Road, which leads to many of the park’s most well-known areas, is only open seasonally from May 1 to October 31.
