Redwood National Park is a United States National Park and a UNESCO World Heritage Site that is located on the North Coast of the state of California. The park protects several groves of massive redwood trees, which can live for 2000 years, grow to heights of up to 367 feet, and be as wide as 22 feet at the base of the trunk. Created by Congress to protect lands adjacent to three California state parks (Jedediah Smith Redwoods State Park, Del Norte Coast Redwoods State Park, and Prairie Creek Redwoods State Park) in 1968 with the creation of Redwood National Park. In 1994, the California Department of Parks and Recreation and the National Park Service agreed to jointly manage the four-park area for maximum resource protection.
Temperatures range from 40 to 60 degrees(F) (4 to 15 degrees C) year round along the redwood coastline. Redwoods rely on the fog that envelops the coast in the summer. Summers are mild at the coast with warmer temperatures inland, but the aforementioned fog can be a problem, often thick as pea soup and lasting for days to weeks. Early to middle spring and early autumn are a safer bet for sunny days. Winters are cool with considerable precipitation. Pack your rain gear and good walking shoes for the slippery rain forest. Wear layers to accommodate cool to warm temperatures.
The trails are especially beautiful in the early morning hours or on days of light to medium fog. In the early morning, the sun's angle through the trees produces long beams of light, creating a dramatic theatre of light and shadow and ever-changing shades of green. In the light fog, the forests become a dreamscape of incredible mystery and beauty.
