Discovery Lake is the focal point of Discovery Park. There are picnic areas and a restroom near the water, and there are a bunch of trails that weave around the hillside that leave from the lake.

Double Peak Park marks the top of Double Peak and provides pretty sweet panoramic views from the top of the 1,646-foot summit. The trails reaching the top of the mountain can be pretty tough and are true "mountain trails."
