From carrer de l'Aigua, in Roda de Berà, you pass under the railway line and continue along the old Camí de Bonastre, following the bed of the torrent de Cal Setró. Follow the first turn-off to the left until you reach a water tank. Continue along the ridge to the Torre del Cucurull and the turó del Cucurull. Right at the col that follows, you must turn west (left) and follow a faint path with fairly visible blue marks that lead to the small cave.
