I visited this beautiful light house on the trip to Revdanda sea beach, its just 3~4 kms away from Revdanda and u can experience the sunset from the light house, it looks beautiful from the top. They start the light in the light house at 6 pm, every evening.One u pay the entry fee, the light-keeper takes u to the top & explains all technical details like frequency of light flash, what is the use of light house, what if the main light fails, the fall back, the remote control system ( which can control the light house from Mumbai control room), how it operates in day time (using electronics) etc.
also the light house official timings are 16.00 hours to 17.30 hours
