What it is
Bai Mon is a crescent-shaped beach tucked beneath granite cliffs at the tip of Mui Dien (Cape Dien), the easternmost point of mainland Vietnam (베트남 / 越南 / ベトナム). A French-built lighthouse from 1890 still operates on the headland above, 100 meters over the sea. The whole area sits in Hoa Tam commune, Dong Hoa district, Phu Yen province — about 34 km southeast of Tuy Hoa city.
The lighthouse was constructed during colonial administration to guide ships through the coastal shipping lane between Quy Nhon and Nha Trang (냐짱 / 芽庄 / ニャチャン). It survived wars and typhoons, was restored in 1995, and remains one of the oldest functioning lighthouses in Vietnam. The beach below — roughly 300 meters of coarse white sand flanked by dark boulders — stayed off the tourist radar until the early 2010s.
Why travelers go
Three reasons people make the trip: the sunrise, the isolation, and the hike.
Bai Mon faces due east with zero obstruction. If you're chasing the literal first sunrise on mainland Vietnam, this is the coordinates. Beyond bragging rights, the beach is genuinely empty most weekdays — no loungers, no vendors, no jet skis. The water is clear enough to snorkel off the rocks on calm days.
The trail down from the parking area to the beach drops about 200 meters over roughly 500 steps carved into the hillside. It's not technical, but it filters out the tour-bus crowd. You earn the swim.
Best time to visit
Phu Yen's dry season runs from January through August. The sweet spot is March to June — skies are clear, seas are calm, humidity hasn't peaked yet. Water temperature hovers around 26-28°C.
Avoid October through December: the northeast monsoon brings swells that make the beach dangerous and the trail slippery. The lighthouse stays open year-round, but the beach access path can close during storms.
Weekends in summer (June-August) bring domestic visitors from Tuy Hoa and Quy Nhon. Go on a Tuesday or Wednesday morning and you might have the cove to yourself.

How to get there
From Tuy Hoa: Rent a motorbike (120,000-150,000 VND/day from guesthouses near the train station) and ride south on QL1D, then cut east at the Hoa Tam junction. Total distance is 34 km, about 50 minutes. The last 8 km is a narrow concrete road winding through fishing villages — scenic but watch for dogs and drying fish nets on the road.
From Quy Nhon: 120 km north along QL1A, roughly 2.5 hours by motorbike or 2 hours by car. You can also combine it with a stop at Bai Xep (the fishing village from the film "Yellow Flowers on the Green Grass") on the way.
From Da Nang or Hoi An: Take the train to Tuy Hoa (about 4 hours from Da Nang, tickets around 150,000-250,000 VND for a hard seat). Then motorbike or taxi from there.
Entrance fee: 20,000 VND per person at the gate. Motorbike parking is 5,000 VND.
What to do
The lighthouse hike
From the parking lot, walk up the paved path to Mui Dien lighthouse — about 15 minutes. The keepers usually let you climb to the top for photos. Views stretch north toward Vung Ro Bay and south toward Hon Nua island. Best light is obviously sunrise, but late afternoon gives you golden cliffs without the 4:30 AM alarm.
Bai Mon beach
Head down the steps (bring water — there's no shade on the descent). The beach has no facilities except a single drink kiosk that operates sporadically. Swimming is good in the center of the bay; the edges have submerged rocks. Snorkeling is possible along the southern boulder field when seas are flat — expect small reef fish and sea urchins.
Vung Ro Bay detour
On the ride back, Vung Ro Bay is only 10 km north. It's a deep natural harbor with quiet beaches and a small war-history museum (related to the supply route during wartime). The bay has several seafood shacks right on the water.
Where to eat
There's nothing at Bai Mon itself beyond that unreliable drink kiosk. Pack snacks and water for the beach.
On the road back, stop in Hoa Hiep Nam village for seafood. Look for the cluster of "quan hai san" signs near the fishing port. Grilled squid, steamed blood clams, and "banh canh" with fish cake are the local standards. A full seafood meal for two runs 200,000-350,000 VND.
In Tuy Hoa, the city's signature dish is "banh canh (반깐 / 粗米粉汤 / バインカイン)" he (crab noodle soup) — thick tapioca noodles in a briny crab broth. Quan Ba Cu on Tran Hung Dao street is the local pick. A bowl costs 35,000-45,000 VND.
For morning fuel before a sunrise trip, grab a "banh mi" from any cart near Tuy Hoa market — they use a local pork roll that's slightly sweeter than the Saigon style.

Where to stay
Bai Mon has no accommodation. Base yourself in Tuy Hoa (34 km) or at one of the small guesthouses in Song Cau town (45 km north, quieter).
Budget: Nha nghi (local guesthouses) along Le Duan street in Tuy Hoa run 200,000-350,000 VND/night. Basic but clean, most include motorbike parking.
Mid-range: CenDeluxe Hotel in Tuy Hoa (600,000-900,000 VND) is the best value with a pool and sea views. Rosa Alba Resort on Tuy Hoa beach is a step up at 1,200,000-1,800,000 VND.
Homestay option: A few families in Hoa Tam commune offer rooms (ask at the entrance gate) — around 250,000 VND with dinner included. Don't expect English.
Practical tips
- Bring reef-safe sunscreen — there's zero shade on the beach or the steps.
- Wear proper shoes for the descent, not flip-flops. The steps are uneven and can be slick with morning dew.
- Carry cash. There's no ATM past Tuy Hoa city center.
- If you're riding a motorbike, fill up in Tuy Hoa. The last petrol station is in Hoa Hiep.
- Phone signal (Viettel, Mobifone) works at the lighthouse but drops on the beach.
Common mistakes
Arriving after 8 AM for sunrise. First light hits around 5:15-5:30 depending on season. Leave Tuy Hoa by 4:15.
Underestimating the steps. 500 steps down means 500 steps back up in the heat. Bring 1.5 liters of water minimum per person.
Skipping Vung Ro Bay. It's right there on the return route and has better food options than anywhere near Bai Mon. Don't make two trips when one loop covers both.
Going on a weekend in July. Vietnamese families pack the parking lot and the kiosk runs out of drinks by 9 AM. Midweek is a different experience entirely.
