It is also known as 'No Wave Bay', nestled 80km to the south of Hanoi, and boasting the Red River Delta's largest wetland with mirror-like tranquil water.
Located in the north of Gia Vien district, the wetland reserve, dotted with spectacular islands and caves, was created by a 30km flood-prevention dyke hugging the left bank of Da River. At 60,000 VND (2.6 USD) per person (maximum two passengers per boat), an hour-long, guided row across this 3,500-hectare lagoon will make clear the origins of its nickname.
This popular Ninh Binh destination holds two national records, one for the biggest group of Delacour's langurs, a critically endangered species at home and abroad, and the other as the "largest picture of nature".
