Take a Hike That Leads You to an Abandoned Plane Crash
It's in the Olympic National Forest's Buckhorn Wilderness and it's one of those cool hikes that will take to a plane crash and an awesome abandoned mine, making it well worth the hike.
It's called the Tubal Cain Trail near Sequim and it's Trail 840. The hike include an abandoned B-17 crash sight and a retired copper mine. The total trail is roughly 7 miles round trip and the views are pretty epic.
It's definitely worth checking out and would make for a cool weekend trip. You can check out the photos and more details on the trail here
