Cycle along country lanes, woodland trails or traffic-free routes. Try The Saundersfoot Tramway, The Brunel Trail, Castlemartin, Llys y Fran, Pantmaenog Forest (Rosebush) or Castle Dock Wood (Stackpole). These routes are suitable for families and individuals apart from Castle Dock Wood which is more suitable for off road bikes as it can get quite muddy.
To hire bikes try Mikes Bikes in Haverfordwest
Cycling can be combined with public transport using the coastal bus service.
