Bewl Valley Reservoir is on the A21 between Sevenoaks and Hastings, a mile or so south of Lamberhurst. Turn south on to the A21 from the M25. Before reaching Lamberhurst follow the new bypass and after you rejoin the old A21 you will find a clearly signed right turn to the Reservoir just after the road becomes a dual carriageway. The overnight stay area for the UKWA Inland Series event will be clearly signposted (it is the overflow carpark just up the hill from the clubhouse).
