From Highway A4, take the exit Monfalcone Ovest-Redipuglia. Turn left on road SS305 to Redipuglia and follow directions for the chapel of the Redipuglia Memorial (about 2 kilometres). Once you reach Vermegliano, soon before the Memorial, turn right to Via Carso (towards Doberdò del Lago) and park your car near the sign indicating the entrance of the Sinkhole of the 15th Marksmen Regiment.
