Redwood National Park comprises a region of coastal mountains bordering the Pacific Ocean. It is covered with a magnificent forest of coastal redwood trees, the tallest and most impressive trees in the world. The marine and land life are equally remarkable, in particular the sea lions, the bald eagle and the endangered California brown pelican. The park protects several groves of massive redwood trees, which can live for 2000 years, grow to heights of up to 112 metres, and have a diameter of 4 metres at the base of the trunk. The park contains some of the tallest and oldest known trees in the world. Besides tallest trees on Earth the park also protects vast prairies, oak woodlands, wild riverways, and nearly 40 miles of rugged coastline.
