The Hoh Rain Forest and the Olympic Peninsula tied in this touchy-feely category. We presume you meant the National Park section of the Peninsula, where the Hoh is located; it's pretty much loaded with huggable trees. And given the history of logging on the peninsula and the spotted owl/old-growth timber controversy, it seems fitting that this is where you choose to hug your trees.
