Nui Chua National Park protects a rare land–sea ecological continuum on Vietnam's south-central coast in present-day Khanh Hoa. Established as a national park in July 2003 after earlier coastal protection and dry-forest nature-reserve stages, it covers 29,865 hectares in the established national profile: 22,513 hectares of terrestrial habitat and 7,352 hectares of marine habitat. It forms the ecological core of the much larger 106,646-hectare UNESCO Nui Chua Biosphere Reserve, recognized in 2021. The park is not a UNESCO World Heritage property.
Overview
Understand the park as a protected ecological system, not simply a recreation area.
Nui Chua is one of Vietnam's most distinctive protected landscapes because dry tropical forest, semi-arid coastal vegetation, mountain forest, coral reefs, seagrass, rocky shore, tidal habitat and sea-turtle nesting beaches occur within one connected conservation system. NBCA's current national profile gives 29,865 hectares for the park, comprising 22,513 hectares on land and 7,352 hectares at sea. UNESCO's biosphere-reserve boundary is much larger—106,646 hectares, including 99,294 terrestrial and 7,352 marine hectares—and should not be confused with the national-park boundary. In July 2025, the Nui Chua and Phuoc Binh management boards were merged into the Nui Chua–Phuoc Binh National Parks Management Board under Khanh Hoa; the two national parks remain separate protected-area identities. Current 2026 management includes a dedicated marine protected-area plan for 2026–2030, coral and sea-turtle conservation, forest-fire prevention, SMART-supported patrols, environmental education and regulated ecotourism. Nui Chua's visitor appeal—from Vinh Hy and Hang Rai to rocky coast, dry forest and mountain routes—must therefore be framed around conservation controls, heat and fire safety, marine protection and strict respect for turtle nesting habitat.
Key things to understand
Use current provinceSlug khanh-hoa; former Ninh Thuan belongs only to historical/source context.
Keep Nui Chua National Park separate from Phuoc Binh National Park despite their merged management board.
Keep the 29,865-ha national park separate from the 106,646-ha UNESCO biosphere reserve.
Recognize the rare continuum from dry forest and semi-arid vegetation to coral reefs and turtle beaches.
Treat the 7,352-ha marine component as a protected conservation area, not unrestricted recreation water.
Protect sea-turtle nesting beaches from disturbance, light, noise and location disclosure.
Use coral figures with inventory/source context rather than treating them as permanent live counts.
Take extreme heat, drought and forest-fire restrictions seriously.
Verify trekking and camping because the management board issued a July 2026 notice tightening organization of these activities.
Do not collect corals, shells, plants, wildlife or other natural material.
Distinguish UNESCO Biosphere Reserve from UNESCO World Heritage.
Enable only Nature Map; do not enable Heritage Map.
Park perspective
How to understand this protected landscape
Why it matters
Nui Chua conserves one of Vietnam's rarest ecological combinations: dry tropical forest and semi-arid mountain vegetation directly connected to coral reefs, seagrass and sea-turtle nesting beaches.
What makes it distinctive
Few Vietnamese protected areas compress such strong climatic dryness, mountain relief and tropical marine biodiversity into one continuous landscape.
What visitors often miss
The famous coast is only half the story; the same park protects a highly unusual terrestrial dry-forest system and the ecological transitions linking land to sea.
A national park in Khanh Hoa where Vietnam's driest forest landscape runs straight down to coral reefs and sea-turtle beaches.
Protected landscape
Why this national park exists
Identity
Protected Area Role
Land–sea national park conserving Vietnam's signature dry-forest, semi-arid and coastal-marine ecological continuum.
Biosphere Role
Core conservation landscape of the UNESCO Nui Chua Biosphere Reserve recognized in 2021.
Marine Role
Protects coral reefs, seagrass, intertidal habitat and important sea-turtle nesting beaches.
Forest Role
Protects an unusually dry tropical forest system alongside higher and moister mountain vegetation.
Visitor Role
High-value nature destination where tourism must be regulated around fragile terrestrial and marine habitats.
Core Insight
Nui Chua is exceptional not because it is simply dry or coastal, but because desert-like vegetation, forest, mountain and tropical marine ecosystems are ecologically connected in one protected landscape.
Designation
Coastal Protection
A coastal protection-forest management stage dates to August 1993 in the NBCA history.
Nature Reserve
Nui Chua dry-forest nature reserve was established in 1998.
National Park
National park established in July 2003; NBCA cites Decision 134/2003/QĐ-TTg dated 9 July 2003.

Ecosystems
Connected habitats shape the protected landscape
01
Tropical dry forest and semi-arid scrub
Heat- and drought-adapted vegetation across exposed low and middle elevations.
Why it matters
Rare ecosystem expression in Vietnam.
Visitor impact
Fire, trampling and plant collection can cause serious damage.
02
Moister mountain and conifer-influenced forest
Higher/cooler sectors support forest structurally different from the arid lowlands.
Why it matters
Adds major ecological diversity within a compact mountain system.
Visitor impact
Off-route trekking can damage sensitive vegetation.
03
Coral reefs
Extensive reef system along the park's marine coast.
Why it matters
High marine biodiversity, nursery habitat and coastal resilience.
Visitor impact
Anchoring, trampling, touching and pollution damage reefs.
04
Seagrass beds
Shallow marine meadows ecologically linked to reefs and coastal fauna.
Why it matters
Feeding, nursery and carbon-storage functions.
Visitor impact
Propellers, anchoring and sediment disturbance can degrade beds.
05
Sea-turtle nesting beaches
Small sandy beaches used by nesting marine turtles.
Why it matters
Among mainland Vietnam's most important turtle reproduction habitats.
Visitor impact
Lights, noise, crowds, vehicles and touching turtles/hatchlings are harmful.
06
Rocky shore and intertidal habitat
Wave-exposed rock fields, tidal pools and coastal cliffs.
Why it matters
Distinctive ecology and scenery.
Visitor impact
Slippery rock, collecting and trampling require control.
Conditions & safety
Weather, terrain and preparation shape the visit
Safety
Prepare for terrain, weather and changing conditions
Low Impact Practice
Use only authorized trekking and camping arrangements.
Carry sufficient water and sun protection.
Never light unauthorized fires.
Do not collect plants, coral, shells or wildlife.
Never stand on or touch coral.
Use moorings/authorized boats rather than damaging reef with anchors where applicable.
Keep lights and noise away from turtle nesting beaches.
Never touch turtles, eggs or hatchlings.
Carry out unmanaged waste and reduce single-use plastic.
Do not publish sensitive turtle or wildlife coordinates.
Respect marine zoning and fishing restrictions.
Keep bird/wildlife disturbance low.
Respect community land and cultural practices.
Do not assume drone permission.
Follow ranger, weather, fire and marine-safety instructions.
