Pathways are rough and uneven and there's zero food or water sold inside - carry your own. Go for the cliff views, the ruins themselves are minimal.
The fort takes its name from the Ramayana legend that Lord Rama and Sita sheltered at this cliffside site during their exile, and it was originally held by local Hindu rulers before passing between Hindu and Muslim regional powers for centuries. The Portuguese acquired it in the 1760s after the Raja of Sonda ceded the territory in exchange for military protection against Hyder Ali of Mysore, and they rebuilt it with ramparts, a moat, and a chapel. The fort was later repurposed as a government prison, which operated until 1955.
