Son Tra Nature Reserve protects the forested mountain of Son Tra Peninsula immediately northeast of central Da Nang. National biodiversity information records a 4,370-hectare peninsula protected since 1977 under Decision 41/TTg, with tropical evergreen forest, freshwater resources and unusually rich wildlife compressed into a small coastal landscape. The reserve is especially important for the red-shanked douc langur and for maintaining a continuous ecological transition between mountain forest, rocky coast and surrounding sea.
Overview
Understand the reserve as one connected ecological system.
Son Tra is one of Vietnam's most unusual urban-adjacent conservation landscapes: a steep forested peninsula rising directly from the coast beside a major city. The national biodiversity authority records the peninsula at 4,370 hectares and traces formal nature-reserve protection to Prime Ministerial Decision No. 41/TTg dated 24 January 1977. Its current national conservation classification is presented as a species-and-habitat conservation area. The peninsula extends roughly 13 km east–west, is about 1.5–5 km wide and has around 60 km of perimeter, about three quarters adjoining the sea. National conservation data report an average elevation of about 350 m and a highest point around 696 m. The landscape supports tropical evergreen forest, streams and springs, coastal cliffs and marine-edge habitats. A 2017 fauna inventory cited by the national authority recorded 42 mammal species, 162 bird species, 55 reptiles, 22 amphibians and 231 insects; the same profile records 1,010 higher plant species in 483 genera and 143 families. Son Tra's best-known conservation symbol is the red-shanked douc langur, but the reserve should not be reduced to wildlife photography: forest integrity, freshwater, slope stability, coastal ecology, road management and visitor behavior are all part of its conservation story.
Key things to understand
Understand Son Tra as a protected forest peninsula first, not simply a scenic driving loop.
Treat the red-shanked douc as a conservation flagship rather than a guaranteed photography subject.
Keep the 4,370-ha national biodiversity figure distinct from other planning or peninsula-area figures such as 4,439 ha used in some Da Nang planning material.
Recognize the unusual continuity between mountain forest, rocky coast and surrounding marine environment.
Protect springs and headwaters as part of Da Nang's local ecological infrastructure.
Use roads and viewpoints without feeding, crowding or blocking wildlife.
Never publish sleeping trees, predictable troop locations or other sensitive primate-location data.
Keep noise low around langurs and other wildlife.
Do not treat roadside access as permission to enter protected forest off-route.
Recognize defense, communications and other restricted infrastructure on the peninsula and obey access controls.
Check current road restrictions, weather and conservation notices before visiting.
Keep the Nature Map identity separate from beaches, temples and other individual Son Tra places.
Reserve perspective
How to understand this protected landscape
Why it matters
Son Tra demonstrates whether a rapidly growing coastal city can retain a functioning forest ecosystem and viable threatened-primate habitat immediately beside urban development.
What makes it distinctive
A compact mountain forest rises directly from Da Nang's coast, supporting red-shanked doucs only minutes from dense urban districts.
What visitors often miss
The reserve's value is not just seeing a colorful primate; freshwater, forest structure, road ecology, coastal connectivity and visitor behavior determine whether the system remains viable.
Da Nang's forested coastal mountain—a protected home for red-shanked doucs where rainforest, city and sea meet.

Visitor Lesson
A compact peninsula contains steep elevation changes, exposed coastal roads, humid forest and rapidly changing visibility.
Ecosystems
Connected habitats create the reserve's ecological value
01
Tropical evergreen forest
Dense and recovering forest on steep mountain slopes.
Why it matters
Primary terrestrial habitat for red-shanked doucs and other wildlife.
Visitor impact
Road disturbance, feeding, off-route access, fire and fragmentation can degrade habitat.
02
Ridge and summit forest
Wind- and cloud-exposed vegetation at higher elevations.
Why it matters
Adds elevational diversity and protects headwater catchments.
Visitor impact
Infrastructure and concentrated visitation can fragment sensitive ridge habitat.
03
Stream and spring habitat
Small freshwater systems descending from the mountain.
Why it matters
Supports wildlife and local hydrological functions.
Visitor impact
Litter, contamination and catchment disturbance reduce water quality.
04
Rocky coastal forest edge
Forest descends toward cliffs, coves and exposed shorelines.
Why it matters
Creates Son Tra's distinctive forest-to-sea transition.
Visitor impact
Road expansion and unmanaged access can sever ecological continuity.
05
Marine-edge landscape
Nearshore waters, reefs and coves surrounding the peninsula.
Why it matters
Ecologically and visually connected to the terrestrial reserve even where governed under separate marine frameworks.
Visitor impact
Anchoring, litter, reef damage and coastal development can affect the wider peninsula system.
Biodiversity
Forest, plants and wildlife reveal the conservation stakes
