Make your way to the check-in counter at least 30 minutes of departure times at Villa T7, Tuan Chau Marina, Halong City. Get aerial views of Halong Bay on a 25-minute sightseeing flight in a seaplane, and discover a unique perspective on a landscape that’s been designated a UNESCO World Heritage Centre. See some of the 1,600 islands and islets that are scattered across the Gulf of Tonkin, along with lagoons, beaches, and towering sea cliffs. Keep your camera at the ready throughout the trip, as aerial photographs are the best way to capture the grand scale of Halong Bay, and the vast number of islands and rock formations that define the Gulf of Tonkin coast. You’ll see Dau Be Island, whose sheer cliffs are a destination for rock climbers and adventurers, then fly past Cong Do Island, where the sinuous coastline shelters hidden lagoons. Pass over Bo Hon Island, and try to spot the caves and grottoes that pock the island’s water-eroded rock formations.Read moreMore about Halong Bay
