What Makes Nui Chua Different
Most of Vietnam's forests are tropical rainforest — lush, wet, dense. Nui Chua is one of the only tropical dry forests in Southeast Asia. Less than 700mm of rain per year means the vegetation looks almost like savannah in the dry season: sparse trees, scrubby undergrowth, dramatic rocky outcrops with sea views.
The park covers about 29,000 hectares between Phan Rang and Vinh Hy. Inside: mountain goats, monkeys, rare birds, and a protected sea turtle nesting beach at Hang Rai.
Trails
Nui Chua Peak Trail
Difficulty: Moderate-Hard Distance: ~8km round trip Time: 4-5 hours What you get: The highest point in the park with panoramic views of the coastline, the bay, and into the hills behind. On clear days you can see far north toward Cam Ranh.
Terrain: Rocky path, some scrambling near the summit. Not technical, but steep enough to need proper shoes.
Hang Rai Beach Trail
Difficulty: Moderate Distance: ~5km one way (usually done as a boat + walk combo) Time: 2-3 hours What you get: Hang Rai is a beach made of compacted coral rock rather than sand. The colors — dark rock, bright water — are unlike anything else in the region.
Note: A guide is mandatory for this trail. Book through the ranger station.
Bai Rang Trail (Easier)
Difficulty: Easy-Moderate Distance: 3-4km round trip Time: 2 hours What you get: A shorter coastal trail ending at a rocky beach. Good option if you want nature without the full-day commitment.
Wildlife
The dry forest supports species you won't find in wetter zones:
- Mountain goats (Dê núi): Often spotted near rocky ridges in the early morning
- Long-tailed macaques: Common near the ranger station area
- Birds: 300+ species recorded; notable for rare dry forest specialists
Sea Turtle Nesting
Hang Rai beach is one of the few active sea turtle nesting sites on Vietnam's southern coast. Turtles (mainly green turtles) come ashore to lay eggs roughly May-August. The national park runs a monitoring program.
If you visit during nesting season and ask the ranger station about overnight turtle watching programs, they sometimes arrange it. You cannot disturb the turtles or nesting areas on your own.
Practical Information
Entry fee: 20k VND/person Guide fee: Required for Hang Rai and Nui Chua peak trails. Roughly 300-500k VND for a guide (shared among your group).
What to bring:
- At least 2 liters of water per person (no sources on trails)
- Trekking shoes (not sandals)
- Hat and sunscreen (sparse tree cover, intense sun)
- Snacks (no food on trails, ranger station has limited options)
Best months: March-August (dry, trails safe). Avoid September-November (slippery trails, possible trail closures after heavy rain).
Getting there: The main ranger station is about 20km north of Phan Rang, on the road toward Vinh Hy. By motorbike: 30 minutes.
Register at the Ranger Station
Don't go straight to the trailhead. Stop at the ranger station first to register, get a trail map, confirm which trails are open, and arrange a guide if needed. This is also where they track who's in the park for safety.
