13 Best National Parks to Visit in the US This Summer

8. Olympic National Park, Washington: Temperate Rainforests and Diverse Ecosystems

Olympic National Park encompasses nearly one million acres of Washington State's Olympic Peninsula, creating a UNESCO World Heritage Site that protects one of the most diverse collections of ecosystems in North America, from temperate rainforests to alpine peaks to rugged Pacific coastlines. The park's famous Hoh Rainforest receives over 140 inches of annual precipitation, creating a mystical landscape where massive Sitka spruces and western hemlocks draped in moss and ferns tower over visitors walking through cathedral-like groves that feel like stepping into an ancient, primordial world. Summer provides the driest conditions for exploring the park's extensive trail system, including the challenging Sol Duc Hot Springs to Seven Lakes Basin route and the spectacular Hurricane Ridge area, which offers panoramic views of the Olympic Mountains and access to alpine meadows filled with wildflowers during the brief growing season. The park's 73 miles of wilderness coastline feature dramatic sea stacks, tide pools rich with marine life, and pristine beaches where visitors can explore Ruby Beach's polished stones and Rialto Beach's massive driftwood sculptures while watching for gray whales during their migration periods. Olympic's unique geography creates distinct climate zones within short distances, allowing visitors to experience everything from the temperate rainforest's lush greenery to the alpine environment of Hurricane Ridge, where snow may persist well into summer at higher elevations. The park supports an incredible diversity of wildlife, including the largest unmanaged herd of Roosevelt elk in the Pacific Northwest, black bears, mountain goats, and over 300 bird species, while the surrounding waters provide habitat for orcas, sea otters, and harbor seals. Summer's mild temperatures and reduced rainfall create optimal conditions for backpacking adventures into the park's vast wilderness areas, where pristine lakes, ancient forests, and rugged peaks provide solitude and natural beauty far from civilization's influence.
