Fodor's Expert Review Avenue of the Giants

Some of Earth's tallest trees tower over this magnificent 32-mile stretch of two-lane blacktop, also known as Highway 254, that follows the south fork of the Eel River through Humboldt Redwoods State Park. The highway runs more or less parallel to U.S. 101 from Phillipsville in the south to the town of Pepperwood in the north. A brochure available at either end of the highway or the visitor center, 2 miles south of Weott, contains a self-guided tour, with short and long hikes through various groves.

A trail at Founders Grove passes by several impressive trees, among them the fallen 362-foot-long Dyerville Giant, whose root base points skyward 35 feet. The tree can be reached via a short trail that begins 4 miles north of the visitor center. About 6 miles north of the center lies the 10,000-acre Rockefeller Forest, containing the world's largest concentration of old-growth coastal redwoods.
