Guidaloca, Mediterranean bay and beach in Castellammare del Golfo, Italy.

Guidaloca is a natural inlet on Sicily's northwestern coast in Castellammare del Golfo, bounded east by Punta Gran Marinaro and west by Capo Puntazza. Its beach is made of small white pebbles, and the ancient watchtower Torre Guidaloca stands on the western side.

The bay takes its name from the Torre Guidaloca, a watchtower on its western side. The tower belonged to Sicily's coastal defence network against sea raids; the sources do not date its construction. The beach and cove later served as a filming location for the 2016 film Tini - La nuova vita di Violetta and the 2021 series Màkari.

Small restaurants along the shore serve traditional Sicilian dishes rooted in the area's fishing heritage. Local people gather here regularly, making the beach a place where daily social life meets the sea.

The bay lies between Punta Gran Marinaro to the east and Capo Puntazza to the west, with the beach and Torre Guidaloca on its western side. The shore is made of small white pebbles, so bring footwear for comfort. The bay has been used as a set for commercials and films such as Tini - La nuova vita di Violetta (2016) and Màkari (2021).

The bay between Punta Gran Marinaro and Capo Puntazza served as a filming location for the 2016 movie Tini: The New Life of Violetta and the 2021 series Màkari. Its white pebble beach, rather than sand, is what defines the shoreline.
