While the parks cover 206 square miles, they contain slightly less than half of the total redwood forest. The parks include Redwood Forest National Park, six California state parks, one state resort and two state rest areas.
The park is home to many rivers and streams, but is also a coastal area. The freshwater courses of the park are home to salmon and trout (among others), while the beaches are thick with a wide variety of crustaceans, and whales can be seen offshore.
The combination of coastline and deep forest is home to a wide variety of birds, including bald eagles, several types of owls, pelicans, gulls, hawks and wrens.
The forest offers a habitat for a plethora of mammals, such as various types of bats, black bears, elk, deer, rabbits, otters, cougars, beavers and bobcats.
Sequoia sempervirens (redwood tree) is the biggest tree in the world. A normal example can stand well over 200 feet tall, and the tallest known tree is 379 feet tall.
Redwoods are exceptionally long-lived trees. The oldest known tree is more than 2,200 years old, and it is not uncommon to encounter trees several centuries old in the forest.
