You certainly could. The Olympic Pennisula is easily accessable, just a few hours from Seattle, but in a different world. We took our son there for 2 days after he finished graduate school at UW last June. It's like nothing I've ever seen in my life. Mountains on one side, wild ocean beaches on the other and rain forest in between. The rain forest is part of Olympic National Park. You'll want to park your car and go on one of the walking trails. I had tendonitis in my ankle when we were there and could still manage some of the shorter loop walks. There are boardwalks all over the place and park rangers who love to help. There are also some more challenging hiking trails. My husband and son took one of the longer nature walks and came back with pictures of an elk who wandered across the trail. I was so jealous that I couln't go with them. Someday I want to go back and meet that elk, too! Be sure you pack your foul weather gear. They call it the rainforest for a reason.

We used the Olympia National Park website to help plan our trip.
