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.
