Sơn Trà Peninsula juts into the sea northeast of Đà Nẵng, rising to 696 metres at its summit and covering 4,439 hectares of protected nature reserve. The peninsula's position - three sides surrounded by water, the fourth connected to the city by a narrow isthmus - has preserved its forest in a way that almost nothing else near a Vietnamese city has matched.
Red-Shanked Douc Langurs
Sơn Trà protects one of the world's largest remaining populations of the red-shanked douc langur - a species often described as one of the most beautiful primates on Earth, vivid orange, black, white and grey with a face that looks almost painted, and listed as endangered. The peninsula's combination of protected status, accessible roads, and proximity to a major city makes it one of the few places anywhere where visitors can observe this species without deep-forest expeditions.
History
The site carries historical weight as well. On 1 September 1858, French and Spanish forces fired the first shots of their invasion of Vietnam from Đà Nẵng Bay, landing at the foot of this peninsula - the moment that opened nearly a century of colonial rule. A former US radar installation from the 1960s, known as Trạm Radar 29 or the 'Eye of Indochina', still stands on the slopes; one of Vietnam's eight oldest lighthouses, built by the French and operational since 1902, marks the peninsula's eastern point.
