What it is
Nui Da Bia (literally "Stone Stele Mountain") is a 706-meter granite peak in Dong Hoa district, Phu Yen province, about 30 km south of Tuy Hoa city. The mountain's distinctive flat-topped boulder summit has served as a natural boundary marker for centuries — historical records trace it back to the 15th century when King Le Thanh Tong allegedly had characters carved into the rock face during his southern campaigns. Whether the inscription survives is debated, but the name stuck.
The peak sits right along the coast, roughly 3 km inland from the sea as the crow flies. That proximity gives it an unusual profile: you're climbing through coastal scrub forest and emerging above a panorama that drops straight to the East Sea.
Why travelers go
Three reasons, honestly. First, it's one of the few proper hikes between Da Nang and Da Lat that doesn't require a multi-day commitment or a motorbike loop. Second, the summit view — Vung Ro Bay below, Dai Lanh peninsula curving north, and on clear mornings the coastline unrolling toward Nha Trang (냐짱 / 芽庄 / ニャチャン) — is genuinely worth the sweat. Third, it's still quiet. You won't find tour buses here. Most visitors are Vietnamese day-trippers from Tuy Hoa or motorcyclists doing the coastal route who stop for a few hours.
It's not a wilderness trek. The trail is well-maintained with concrete steps on the steeper sections. Think of it as a vigorous morning hike rather than a mountaineering expedition.
Best time to visit
January through August. Phu Yen's rainy season hits hard from September through December — the trail gets slippery, cloud cover kills the views, and afternoon storms roll in fast. The sweet spot is February to April: dry, not yet scorching, and relatively clear skies.
If you're coming in summer (May–July), start early. By 10 AM the exposed granite sections radiate heat. A 5:30 or 6:00 AM start gets you to the summit before the haze thickens.

How to get there
Nui Da Bia sits just off National Highway 1A, about 30 km south of Tuy Hoa and 50 km north of Nha Trang.
From Tuy Hoa
Ride south on QL1A for roughly 30 minutes by motorbike. The turnoff is signed — look for the entrance gate on the right (west) side of the highway near Hoa Xuan Nam commune. Parking is free at the base.
From Nha Trang
Head north on QL1A, pass through Ninh Hoa, continue over Dai Lanh pass (Ca pass), and the entrance appears on your left about 5 km after descending the pass. Total ride: 50–60 km, about 1.5 hours with a motorbike.
By bus
Any north-south bus running the QL1A corridor passes the turnoff. Ask the driver for "Nui Da Bia" — they'll drop you on the highway. From there it's a 1 km walk to the trailhead.
By train
Tuy Hoa station is the closest railway stop. From there, hire a Grab bike (around 80,000–100,000 VND one way) or rent a motorbike in town for 120,000–150,000 VND/day.
What to do
The main hike
The trail runs about 2.5 km from the parking area to the summit, gaining roughly 500 meters of elevation. Budget 1.5–2 hours up and 1–1.5 hours down. The first half is gradual — paved path through forest, some shade. The second half steepens with stone steps and a few scramble sections near the top. The final push to the summit boulder requires a bit of hand-over-hand climbing on fixed chains.
No technical gear needed, just decent shoes with grip. Flip-flops won't cut it on the upper sections.
Vung Ro Bay detour
After descending, ride 10 minutes south to Vung Ro Bay — a sheltered cove with turquoise water and a few seafood shacks. Combine the hike with a swim and a cheap lunch. Grilled squid and rice runs 50,000–80,000 VND per plate.
Dai Lanh beach
Another 15 minutes south, Bai Mon (Dai Lanh) beach sits at the foot of Mui Dien — Vietnam (베트남 / 越南 / ベトナム)'s easternmost point. Less crowded than anything near Nha Trang.
Where to eat
There's no food at the summit or trailhead beyond a drinks stall selling bottled water and instant noodles. Eat before or after.
- Seafood at Vung Ro Bay: Simple "quan nhau" places line the bay road. Order grilled fish, steamed clams, rice. Two people eat well for 200,000 VND.
- Banh canh in Dong Hoa town: The area is known for "banh canh" — thick tapioca noodle soup. Stalls along the main road serve bowls for 25,000–35,000 VND. Look for places with the most motorbikes parked outside.
- Tuy Hoa city: If heading back north, Tuy Hoa has solid "bun cha" ca (fish cake noodle soup), the local specialty. Try the cluster of stalls near Tuy Hoa train station.

Where to stay
Most travelers don't overnight at Nui Da Bia — it's a half-day stop. But if you want a base:
- Tuy Hoa: Budget hotels (300,000–500,000 VND/night) line Tran Hung Dao street. Nothing fancy, but clean and functional.
- Dai Lanh area: A few homestays and guesthouses have popped up near Bai Mon beach. Expect 250,000–400,000 VND for basic rooms.
- Nha Trang: If you're coming from the south, just do the hike as a morning stop on your way north.
Practical tips
- Bring 1.5–2 liters of water per person. There's no water source on the trail.
- Wear long pants if you want to avoid scratches on the upper scramble sections.
- The site is technically open from 6:00 AM to 5:00 PM. No entrance fee as of early 2024.
- Phone signal is patchy on the trail but fine at the summit (Viettel works best).
- If riding a motorbike, the stretch of QL1A here has fast truck traffic. Stay alert, especially near the Dai Lanh pass descent.
Common mistakes
Starting too late. By midday the exposed rock is brutal and haze obscures the coastal views. Aim to reach the summit by 8:30 AM.
Underestimating the final section. The last 200 meters involve actual climbing on chains. People in sandals or with knee problems struggle here. It's not dangerous, but it's steeper than the trail suggests from below.
Skipping Vung Ro Bay. The hike alone is good but not revelatory. Pairing it with Vung Ro or Bai Mon makes the detour worthwhile.
Driving past it. Most travelers on the Nha Trang-to-Hoi An route blast through this section on a sleeper bus. If you're on a motorbike or have your own wheels, build in a half-day here. The combination of summit views, empty coastline, and cheap seafood is hard to beat between Da Nang (다낭 / 岘港 / ダナン) and Nha Trang.
