      Maple Valley is home to 4 underrated and expansive mostly XC riding areas. Lake Sawyer is an older development, and the largest of the 4, offering mostly twisty, narrow XC singletrack. It connects to BDOS & Summit Ridge across a road. Black Diamond Open Space, or BDOS for short, is a project by Evergreen Mtb Alliance in conjunction with King County parks. It offers mostly more flowy XC singletrack, with some downhill trails. It connects to Summit Ridge, via the 'Connector' trail off Route 66, connects to Henry's Ridge across the train tracks on both Route 66 and Master Link, and connects to Lake Sawyer across the road. Summit Ridge is probably the most famous of the 4. While easily the smallest, it offers the only real downhill and jump trails of the area, such as Gannonball, one of the largest Jump Trails in Washington. It has both a freeride park with trails for every difficulty and an XC area, which also contains many high rated trails. It connects to BDOS at it's main entrance, and to Lake Sawyer across the road. Finally, Henry's Ridge is another area. Similar to Lake Sawyer and BDOS, it's a mostly XC area with some more flowy trails. It has more elevation change on its XC trails than other areas, but there aren't very many real climbs or descents to be found. It connects to BDOS across the rail tracks.
