What Is Hang Rai?
Hang Rai is a rocky beach on the eastern coast of Nui Chua National Park. Instead of sand, the beach is composed of compacted coral and weathered rock formations creating a dramatic dark-rock-meets-turquoise-water contrast.
It's also one of the few active sea turtle nesting sites on Vietnam's southern coast. Green turtles come ashore May-August to lay eggs.
Access: Not a drive-up beach. You must register at Nui Chua ranger station and go with a guide. This is strictly enforced to protect the nesting sites.
The Trek
Trail: ~5km one way from the nearest road access point. Combination of coastal path and rocky scrambling. Takes 1.5-2 hours each way.
Difficulty: Moderate. Not technical, but the terrain is uneven—sharp coral rock, loose stones, some sections exposed to sun. Proper shoes required (not sandals).
What you see: Dry forest, ocean views, occasional wildlife (monkeys, monitor lizards), and the dramatic coastal landscape that makes Nui Chua unique.
At the Beach
The beach itself is small—maybe 200m of accessible coastline. The rocks are dark gray to black (old coral), the water is exceptionally clear.
Swimming: Possible, but the rocky bottom is sharp. Bring reef shoes if you plan to wade in.
Sea turtles: If you visit during nesting season (May-August) and get very lucky, you might see turtles at night. Daytime sightings are rare. Do not disturb nests or approach turtles—rangers will enforce this strictly.
Photography: The color contrast (dark rocks, bright water) makes this one of the most photogenic beaches in Vietnam. Best light is early morning or late afternoon.
Booking a Guided Trek
Where: Nui Chua National Park ranger station (on the road between Phan Rang and Vinh Hy, ~20km from Phan Rang).
Cost: Guide fee ~300-500k VND for a group (up to 4-5 people). Entry fee to the park: 20k VND/person.
When to book: Ideally 1-2 days ahead by phone or in person. Last-minute same-day bookings sometimes work if a ranger is available.
What's included: Ranger guide for the trek, safety briefing, basic info about the park and turtle conservation.
Duration: Plan for 5-6 hours total (2 hours hiking in, 1-2 hours at the beach, 2 hours hiking out).
Best Time to Visit
Season: March-August (dry season). The trail can be muddy and slippery after rain.
For turtles: May-August nesting season. Even then, daytime sightings are rare. If you want to see turtles, ask the rangers about organized night watches (not always available, depends on conservation program schedule).
Time of day: Start early (7-8am departure) to avoid hiking in peak afternoon heat.
What to Bring
- Water (2 liters/person minimum—no water sources on trail)
- Hiking shoes or sturdy sneakers (not sandals, not flip-flops)
- Hat and sunscreen (trail is exposed)
- Snacks/lunch (no facilities at the beach)
- Reef shoes if you want to swim

Combining with Vinh Hy
Hang Rai is accessible via a trailhead near Vinh Hy Bay. If you're staying overnight in Vinh Hy, you can arrange the trek from there. Some Vinh Hy homestays help coordinate with the rangers.
Alternatively: Drive to the ranger station, do the Hang Rai trek, then continue to Vinh Hy for lunch and swimming (easier beach access, no guide needed).
