Coed y Brenin was Britain's first purpose-built mountain biking center and it remains one of the sport's top destinations. Eight purpose-built mountain bike trails start at the visitor center and range from easy trails for families and beginners to technical trails for experienced mountain bikers. Other facilities for mountain bikers include a bike shop and a skills room where you can develop your riding techniques. The visitor center is also the starting point for walking and running trails through the Coed y Brenin Forest Park, as well as orienteering courses and geocaching. Two of the walking routes are suitable for visitors who use an off-road mobility scooter. There are also children's play areas, a café and plenty of picnic tables.
