Skrivena Luka, also known as Portorus, is one of the biggest and the most beautiful bay on the island of Lastovo. Skrivena Luka means Hidden Harbour, and it is true that the bay can not be seen from the open sea. Skrivena Luka is located on the southern part of the island and is protected from the rough sea and strong winds. With 7 km long road, the bay is connected with the village of Lastovo, 17 km away is the port of Ubli. It is the hottest place on the island, too, making it vulnerable to the forest fires. The pine forests were destroyed several times, but not completely, there is still nice vegetation intact, especially close to the sea coast. The lighthouse Struga (built 1839), one of the oldest on the Adriatic sea, is hovering over the bay, reminding us of the old times, when the sailboats and the steamboats were depending on it.
