This a great day trip hike if you live in Olympia area. Myself and my husband were pleasantly surprised at how serene and quiet it was this time of year too. Huge old growth trees right at the entrance and in many other spots. Overall a heavily shaded trail, relatively flat, about 4.5 miles if you hike the entire loop around the park. There is also a great beach area with swimming, kayaking, fishing, picnic tables, bathrooms, etc. so you could do a lot more here if you wanted or you can choose to hike through it or around it.
