trail is a good example of old-growth redwood forest and contains a few very big trees, including the Founder's Tree (346.1. ft. tall) and the Dyerville Giant (c. 370 ft. tall) which fell down in 1991. Drive-Through Tree Avenue of the Giants features a tree that visitors can drive through. Shrine Drive-Thru Tree is near the town of Myers Flat. The tree is privately owned; the owner charges $8 or more for a car to drive through it. Tree House Not a traditional tree house, this is actually a house that is, albeit partially, built within a giant redwood. Visible from the road, and with tours available, the front of this house is entered through the hollow trunk of a still-living tree. The front door and windows are clearly visible to passers-by, and the rest of the house adjoins the rear of the tree in a more traditional style. Eel River and South Fork The Eel River is the third largest river in California. It carves deep canyons down great mountains, through flat valleys, and past majestic and ancient redwood forests. The Avenue of the Giants follows the South Fork of the river, but also features the branching of the South and Main forks to its north. History The Avenue of the Giants was part of U.S. Route 101 until a freeway bypass was completed on August 27, 1960, assuming the 101 designation. The Avenue was then designated as CA Route 254 by Assembly Concurrent Resolution 10.
