I took a quick weekend trip after scoring a $175 roundtrip on Delta from OKC-SEA to the Olympic peninsula. Olympic National Park is nothing short of amazing, and I really could have spent more days or even weeks there easily. The highlight was a whale watching tour with Island Adventures in Port Angeles. I spent most of Saturday morning and early afternoon watching whales in the Strait of Juan de Fuca, including a nice breach right next to the boat. Would highly recommend Island Adventures if you are up there.
