Redwood National and State Parks are home to some of the world's tallest trees: old-growth coast redwoods. They can live to be 2000 years old and grow to over 300 feet tall. Spruce, hemlock, Douglas-fir, berry bushes, and sword ferns create a multiple canopied understory that towers over all visitors. The parks' mosaic of habitats include prairie/oak woodlands, mighty rivers and streams, and 37 miles of pristine Pacific coastline. Leashed pets are allowed on Crescent and Gold Bluffs beaches, in developed areas, such as picnic areas, parking lots, and along gravel and paved roads. Pets are not allowed in the buildings or on the trails. Leashes must be no longer than six feet. Note: Keep dogs away from dead fish found along the river banks. Raw salmon, if eaten, is extremely toxic.
