The Best US National Parks to Visit in Summer

1. Crater Lake National Park, Oregon

Home to winter wonderland-like scenery during the winter, the landscape you’ll find at Crater Lake National Park is equally breathtaking in the summer.

The best time to visit this stunning Oregon national park for great weather and hiking is from July to September. The rest of the year, the landscape gets blanketed in snow, which is gorgeous to look at but makes it pretty difficult to access, especially when you consider snow can reach heights of 40 feet!
