Mandvi Beach

Mandvi Beach, also known as Kala Samudra or Black Sea, is a prominent beach located near Ratnagiri town in Maharashtra. It is distinguished by its unique black sand and is referred to as the Gateway of Ratnagiri due to the historic bastion structure at the bay's head. The beach extends to Rajiwanda Port and is flanked by Ratnadurg Fort. It is one of the busiest beaches in the region, popular for water sports, evening walks, and sunset views.

Visitors can expect a wide stretch of black sand shoreline bordered by the Arabian Sea and Ratnadurg Fort. The beach features a historic jetty-like structure known as the Gateway of Ratnagiri with a walkway offering sea views. Food stalls and benches are available along the promenade. The area is often crowded, especially in the evenings, and offers opportunities for water sports, sunrise and sunset viewing, and casual walks. Swimming conditions should be verified locally as the beach is known for strong currents.

The Gateway of Ratnagiri structure at the beach is believed to have been built by Pratinidhi Dhondu Bhaskar as a defense artwork during the Peshwa regime to protect the shoreline. The adjacent Ratnadurg Fort was improved by Maratha admiral Kanhoji Angre between 1750 and 1755.

Known locally as Kala Samudra (Black Sea), the beach is a significant recreational spot for Ratnagiri residents and serves as a traditional gathering place for evening outings and festivals.
