There are many big trees in the Olympics, but this enormous cedar is so large it has a trail named after it. Plus, it's just a quarter mile from the road. Unfortunately, storms in 2016 felled the large tree, though it's no less impressive. When you visit, be sure to take only pictures -- the Park Service is leaving the giant there in order to perpetuate the natural cycle.
Unlike many short nature trails in national parks, this is no cakewalk. The trail is full of roots, muddy (in the wet season) and steep in parts. The mud gets particularly thick near the tree itself. Wear proper footwear -- trip reporters have had boots sucked right off their feet by the boggy muck.
WTA Pro Tip: If you'd like to get a sense of an enormous tree still (partially) standing, visit the Big Cedar Tree near Kalaloch. While it too has suffered under storms, it's still standing, and WTA crews have improved the short trail in the past.
