More than 300 million people visited U.S. national parks last year, proving that getting outside is still high on Americans’ travel wish lists. KAYAK’s 2026 WTF Report backs that up: 63% of younger generation Americans say natural wonders and immersive outdoor experiences are among the biggest influences on where they travel this year. And with extreme heat affecting much of the U.S. this summer, more travelers are looking for cooler ways to enjoy the national park experience.

To help travelers beat the heat, KAYAK compared average temperatures at U.S. national parks with cooler alternatives at home and abroad for those willing to venture farther. We also analyzed average flight prices to the nearest airport, rental car costs for airport pick-up, and drive times from the airport to each park to uncover cooler national park escapes for late summer and fall, and what travelers can expect to pay to get there.

Cooler national park adventures beyond North America.

Willing to go further? There are plenty of international national parks abroad worth adding to the list. From the Nordics’ glaciers and fjords to Eastern Europe’s alpine forests, some of the world’s best outdoor escapes are more accessible than travelers might expect.

In the Nordics, expect dramatic landscapes shaped by glaciers, fjords and mountain plateaus. Late-summer temperatures typically range from 50–57°F, dropping to around 38–43°F in fall.

For a slightly milder option, look to the Baltics and Eastern Europe. Parks here pair ancient forests, mountain scenery and coastal wetlands with average temperatures of 61–62°F in late summer and 46–47°F in fall.
