Lang Co offers a serene and idyllic panorama of crystal-clear waters overlooked by the Annamite Cordillera and covered by jungle. Also known as Heaven's Door, this beautiful lagoon is very clean and home to a varied ecosystem that includes crabs, snappers, red mullets, grouper, shrimp, squid, etc. Surrounded by an amazing landscape of clear water and mountains, this is a great spot for some snorkeling and swimming. This half-day tour is an exclusive and authentic experience off the beaten track. As such, some facilities are considered basic. The trip can be combined with transfers from Hue to Hoi An or vice versa.
