Cu Lao Xanh (Nhon Chau) sits about 20km from the mainland. Boats cross from Quy Nhon, landing at a village where life still follows the tides.

Climb to the century-old lighthouse for a full-circle panorama, swim in rocky coves with some of the clearest water in the area, and finish with fresh seafood by the pier.

Galaxy Hotel's front desk can arrange the boat trip — call/Zalo 0909 287 343.
