Isla Mancera
Castillo de San Pedro de Alcántara
A small island in the Valdivia river mouth, home to the 17th-century Castillo San Pedro de Alcántara and the ruins of a monastery. It is a classic stop on river cruises.
Isla Mancera sits in the middle of the river mouth. The Castillo San Pedro de Alcántara on the island was built in 1645 and once served as the command center of the fort complex. Its surviving features include walls, a powder magazine, and the ruins of a Franciscan monastery and church. The island is tiny, and walking around it takes about an hour, with grassy slopes offering views around the perimeter. A ferry from the Niebla pier takes about 10 minutes, or you can join a fort cruise departing from Valdivia. Admission includes access to the ruins.
