After a small parking place and behind a little church, you will have to take some steps to get down on the beach. Out of reach for most of the tourists as it is not next to the most of the hotels, you could find your peace on it.
Once you get there, you can enjoy the view on Dubrovnik Old town, Betina cave where Rudjer Boskovic experimented with optics and the blue roof of villa Scheherazade, the most exclusive villa in Dubrovnik
If you are about to take the bus to the St.Jacob's, take the bus number 8 to the last stop, then take the stairs going down, go left when you reach the lower road and keep going until you go behind the church. On your right you'll see the sign and stairs leading to the beach
