When summer temperatures soar, America’s national parks offer a refreshing escape—if you know where to go. From misty rainforests to glacier-fed lakes and breezy coastlines, these parks promise adventure and comfort even in the hottest months. Here’s your guide to the coolest national park experiences for summer.
Olympic National Park, Washington
With its lush rainforests, rugged coastline, and snow-capped peaks, Olympic National Park is a haven for those seeking cool, diverse landscapes. The park’s unique geography means you can experience three distinct ecosystems in a single day: temperate rainforest, alpine mountains, and wild Pacific beaches.
Top Ways to Stay Cool:
- Hike the Hoh Rain Forest: Shaded by towering trees and draped in moss, the Hoh offers gentle, cool trails like the Hall of Mosses and Spruce Nature Trail. Early mornings are especially magical, with mist rising from the forest floor and the sound of the Hoh River nearby.
- Explore the Coast: Visit Rialto, Ruby, or Second Beach for tidepooling, sea stacks, and brisk Pacific breezes. Sunset picnics on the sand are a must, and the cool ocean air keeps temperatures comfortable even on the hottest days. Look for bald eagles and sea otters along the shore.
- Swim or Paddle Lake Crescent: This deep, clear lake is perfect for kayaking, canoeing, or a refreshing swim. The water stays cool all summer, and you can rent boats or paddleboards at the lodge. Nearby Marymere Falls Trail leads to a misty waterfall, ideal for a shaded break.
- Climb Hurricane Ridge: At higher elevations, temperatures drop and wildflower meadows bloom. Hike the Hurricane Hill Trail for panoramic views and a cool mountain breeze.
Glacier National Park, Montana
Known for its dramatic peaks and icy blue lakes, Glacier National Park is a paradise for summer adventurers who want to beat the heat. The park’s high elevation and abundance of water features make it one of the coolest places to explore in July and August.
Top Ways to Stay Cool:
- Hike to Avalanche Lake: The trail winds through cedar forests and ends at a stunning, glacier-fed lake—ideal for a picnic and a dip. The shaded path follows Avalanche Creek, with plenty of spots to rest by the water.
- Drive Going-to-the-Sun Road: This scenic route climbs high into the mountains, offering cool breezes and breathtaking views. Stop at Logan Pass for wildflower meadows and mountain goat sightings. Early morning or late afternoon drives are less crowded and cooler.
- Boat on Lake McDonald: Rent a kayak or take a guided boat tour on this iconic lake, surrounded by snow-capped peaks. The water is chilly year-round, perfect for a quick swim or paddle. Don’t miss the colorful rocks along the shoreline.
- Explore Many Glacier: This area is known for its dramatic scenery, cool mountain air, and excellent wildlife viewing. Hike to Grinnell Glacier or take a boat tour on Swiftcurrent Lake.
Acadia National Park, Maine
Acadia’s rocky shores, cool Atlantic waters, and forested hills make it a top pick for a summer retreat. The park’s coastal climate means temperatures are often 10-15 degrees cooler than inland, and ocean breezes provide natural air conditioning.
Top Ways to Stay Cool:
- Bike the Carriage Roads: Shaded by trees and winding past lakes and ponds, these historic roads are perfect for a breezy ride. Rent bikes in Bar Harbor and explore at your own pace, stopping for a lakeside picnic.
- Swim at Sand Beach or Echo Lake: Both offer chilly, refreshing water and scenic backdrops. Arrive early to beat the crowds, and bring a wetsuit if you want to stay in the water longer. Lifeguards are on duty at Echo Lake during summer.
- Paddle or Sail Frenchman Bay: Sea kayaking and sailing tours reveal Acadia’s dramatic coastline and abundant wildlife. Look for seals, porpoises, and even the occasional whale. Sunset paddles are especially beautiful and cool.
- Hike Cadillac Mountain: Early morning hikes to the summit offer cool temps and the chance to be among the first in the U.S. to see the sunrise.
