It’s hard to predict the best time to visit Olympic National Park. With more than a million acres, this vast wilderness in Washington State stretches from the sandy beaches of the Pacific to the peaks of Mount Olympus, across a wide range of distinct ecosystems. Each area features its own weather patterns, with temperatures that vary from season to season and day to day. Imagine temperate rainforests, glacier-capped mountains, and 70 miles of rugged coastline. As a UNESCO World Heritage Site, Olympic National Park is an adventure no matter the season you visit.
