Off the beaten path, northern New Hampshires Milan Hill State Park contains four basic unheated, roomy yurts that sleep up to six and tent sites that serve as base camp for exploring the hillside park. The 1932 fire tower provides North Country vistas. Local schoolchildren developed a treasure hunt nature cache experience through the park.
