22 kilometres from Alibaug, this is a Portuguese fort that is one of the most popular sightseeing spots in the region. This fort was built in 1521 AD, and is divided into three enclosures that contain a church, ruins and a water cistern. The lighthouse here is worth a visit too. The entry on the western side of the fort is the easiest route!
Entry: INR 20 entry fee to the lighthouse. Go early in the morning and come back before 5 PM.
P.S: The trek up to Korlai Fort from the village is on a rugged terrain, so don’t forget to wear comfortable shoes and clothes.
