Lighthouse Beach is a magnificent destination located in the extreme south of Kovalam. It is built on a rocky headland and tourists are not allowed to go inside the lighthouse. There are memorials of Ayyanappilla Asan and Ayyippilla Asan located around the light house which is visited by tourists in abundance. The reverse side of the lighthouse beach is concreted and illuminated. You can almost get all kinds of sea food and all tastes in and around it.
