Olympic National Park covers a large wilderness area with different habitats, from craggy rock beaches to temperate mossy rain forests, glacier-covered mountains (snow on them year round) and groves of old-growth trees, some up to 1,000 years old. There's plenty of hikes for kids in the park, and keep your eyes peeled for elk, deer, bald eagles, Olympic marmots, and fluffy white mountain goats.
Tip: Olympic National Park is quite spread out, so allow plenty of time to visit different areas when planning your visit.
