Trail surface: mostly easy; some very prominent roots, especially in the beginning, and grassy areas can be quite muddy. Mostly flat, no big elevation changes.
Update 11/8/15: Route changed to incorporate Marlu now that the bridge connects it to Reservoir, description updated, new photos.
Our two cents: Nice park for short loops and easy strolls, plus a playground, ball fields, and even canoe and snowshoe rentals in season. For the avid hiker, this is pretty mild but we were able to get a nearly 7 mile loop out of the trails so it is a good option if relatively nearby. Lots of hiking along fields and not remote feeling. Navigating can be a tad difficult.
