Weowna Park is a great place to exercise your legs. Lots of trails go down the length of the park and up and down the slope to Lake Sammamish.
The cache is placed at the north trailhead to the trail system. Beware of muggles coming up behind you as you search. This is a great dawg walking park, and Leo met many new friends during the placement of the cache. Please recover with cover that fits the hint.
