This is a beautiful park I'll definitely come back to. However, the trails are not marked well and the trail map is fairly useless. With construction going on a lot of the side trails are closed. But it is easy to figure out which way you're going. Good for walking and exploring the local flora.

This is an excellent area to walk/run (although I think I remember seeing signs prohibiting running in certain areas, which people seemed to ignore); the setting is still pretty urban, however there are some areas where you cannot believe you are in the middle of a city. Some trails go out onto lake Washington where there is a nice view of Husky stadium. This is by no means a hike, but a really nice nature walk.
