A few suggestions? A boat tour of the sea caves, which go from Vieste to Mattinata, and an excursion by motorboat to the Tremiti islands. A must-doo activity is walking though the Umbra Forest, which offers priceless freshness on hot summer days. Moreover, believers should not miss out on visiting San Giovanni Rotondo, the town of Padre Pio, and Monte Sant’Angelo, famous for the cave of St. Michael the Archangel.
