The Adventure Park at Sandy River Retreat
The Adventure Park at Sandy River Retreat exists on a separate plane from most parks: it's planted in the treetops. From the ground, its balance beams, bouncy wooden steps, and tightropes nearly disappear amid the russet tree trunks and emerald leaves of the forest ceiling. But up there, the obstacles are front and center. Should adventurers find themselves tuckered out by the park's four courses, they can find respite in a ride down one of 13 ziplines.
