If you find yourself on the Olympic Peninsula in western Washington I hope your heading to Olympic National Park. After climbing Mount Olympus you should spend a couple days in the Hoh Rain Forest. The Hoh is one of the largest temperate rain forests in the United States and sees over 12 feet of rain each year. You could hike the 17.3 mile Hoh River Trail to Glacier Meadows which lies on the shoulder of Mount Olympus.
If you're lucky you might spot Bigfoot which is apparently alive and thriving in the Hoh Rain Forest. If that doesn't pan out you'll have to settle for elk, bobcat, black bear and the northern spotted owl.
Roosevelt elk, also known as Olympic elk.
