The Bangaram Island Beach Resort opened to tourism in 1974, but the lack of commercial flights made access difficult. Tourism took off after the Agatti Aerodrome on the nearby Agatti island was commissioned and regular commercial flights from Kochi were established. The resort had 60 cottages. Current alcohol regulations in Lakshadweep allow consumption of alcoholic drinks only on Bangaram Atoll.
The new Thinnakara is owned by locals from Agatti. It will offer numerous adventure activities, including scuba diving, snorkelling, deep sea fishing beside white sand beaches, a calm lagoon and a sparkling, clear coral reef.
