Côn Sơn Island, Marine reserve in southern Vietnam.
Côn Sơn Island is an island off southern Vietnam's coast with golden sand beaches, clear waters, and mountains that drop into the sea. The island features bays and coastal areas that together create a natural sanctuary for marine life.
The island served as a prison colony from 1862 to 1975, where political prisoners were held under harsh conditions. This long period left deep marks on the place and its importance in Vietnamese history.
The Hang Duong Cemetery stands as a place where visitors encounter names and stories etched into stone, serving as a focal point for remembrance and reflection. People come here to pause and connect with the island's difficult past.
The best time to explore is during the drier months when conditions are most pleasant for travel. Arrive early to find the beaches and hiking routes less crowded and enjoy the landscape at a slower pace.
During nesting season from June to September, visitors can watch sea turtles come ashore at night to lay their eggs in protected beach areas. This natural cycle happens year after year and connects the island to a larger marine ecosystem.
