Even if you don't have a dog you can take a walk in the Hoppers. The trails are flat and interconnect.
The Hoppers area is owned by the city, a lot of history in this area, especially in the woods nearby that have the kettle holes that were formed during the ice age. This flat section is considered a dog park and many people take their dogs here to walk. Even though the paths are clear, in the summer areas alongside can be overgrown and you may have to bushwack a short distance to the cache..The terrain level is a little higher because of the possible bushwacking but most of the year there should be no problem. As always keep an eye out for muggles, bring a pen and replace carefully.
