Bhagvati Bundar is an old harbour near Ratnagiri that now works more as a beach stop than a port. The draw is the white sand and the quieter coastal setting, especially if you are already visiting Ratnadurga Fort or the town's other shoreline sights.
It is a simple place rather than a developed attraction. Come for a short walk, sea views, and a contrast with nearby Mandvi Bundar, which is known for its darker sand.
