Keep the exterior wall of the House of the Masks to your left and the House of the Dolphins behind you and to the right. Follow the path towards the sea you see behind a line of columns. When you come out in the open, there is another fork. Keep to the right (but look at the ruins at the end of the path to the left. There is something unexpected behind the wooden railing). At the next fork, go left (but not before enjoying the view from the end of the right-hand path). You should be heading downhill with the white curving wall of the ancient theatre to your right and an impressive marble door of the so-called Hotellerie to your left. Continue until you find the theatre. Rest.
