Many regional parks are connected to each other by a network of regional riding and hiking trails and Class I (paved off-road) bikeways. Riding and hiking trails have a soft surface, typically composed of native soil or decomposed granite (DG). Trails are used by equestrians, pedestrians, and mountain bicyclists. Class I bikeways are paved with asphalt or concrete, and are used by bicyclists and pedestrians
