On Con Son there are several good beaches worth seeking out. Inquire at the hotels about snorkelling-gear rental for about 100,000d per day or rent new gear through Dive! Dive! Dive! for US$10 per day. Bai Dat Doc is a beautiful beach with a long stretch of sand, although most of this is now part of the new Six Senses Con Dao. Keep an eye out for dugongs frolicking in the water off the nearby cape.
Bai Nhat is small and very nice, though it’s exposed only during low tide. Bai An Hai looks appealing, but there are a good number of fishing boats moored nearby, and a few too many sandflies. Bai Loi Voi is another option, but there can be a fair bit of rubbish and lots of sea shells. Bai Dam Trau is arguably the best all-rounder, a secluded cove on the southern end of the island.
Some of the more pristine beaches are on the smaller islands, such as the beautiful white-sand beach on Tre Lon , to the west of Con Son Island. Perhaps the best all-round island to visit is Bay Canh , to the east, which has lovely beaches, old-growth forest, mangroves, coral reefs and sea turtles (seasonal). There is a fantastic two-hour walk to a functioning French-era lighthouse on Bay Canh’s eastern tip, although it involves a steep climb of 325m. Once at the summit, the panoramic views are breathtaking.
