Con Dao

Con Dao sits 230 kilometres south of Ho Chi Minh City in the South China Sea, and the forty-minute flight deposits you in a completely different Vietnam from anything on the mainland. The airport is barely more than a runway. The main town has one market, one road along the waterfront, and a prison complex that occupies a full block and changed the course of Vietnamese history. I stepped off the tiny plane into air that smelled of salt and frangipanier, looked at the mountains rising directly from the bay, and felt immediately that this place existed at a different pace from everything I had left behind.

That prison is where you should begin. The Con Dao Museum and the adjacent Phu Hai Prison camp are genuinely difficult to move through — the conditions documented here, the scale of the suffering, and the names of the dead etched into the walls create a moral weight that colours everything that follows. The Tiger Cages — concrete pits barely tall enough to stand, barely wide enough to lie down in — are the most disturbing historical site I have encountered in Southeast Asia. Vietnamese visitors come here to pay respects, and many arrive in tears. Coming here before you see the beaches is the right order of things.

Why Con Dao deserves more than a long weekend

The beaches absorb the historical weight slowly, deliberately. Dat Doc Beach is one kilometre of fine white sand with the South China Sea on three sides and national park forest on the fourth. There is no development here — no beach bars, no sunbed operators, no hawkers — just the water and the trees and the sound of waves on unspoiled sand. The snorkelling off the headland reveals live coral in remarkable health, the kind you used to find everywhere along Southeast Asia’s coasts before mass tourism and bleaching events arrived. I drifted over a coral garden for forty minutes and counted eight species of fish I could not name.

The island’s interior is equally extraordinary. Con Dao National Park protects 80% of the archipelago’s land area — sixteen islands of dense tropical forest threaded with trails and ringed with some of Vietnam’s best diving. The road around Con Son island’s perimeter passes through tunnels of national park forest, then opens onto clifftop ocean views that make you stop the motorbike and just stand there. The whole circuit takes about an hour. I stopped seven times.

What should you do in Con Dao?

Con Dao Prison Complex — Begin at the main museum on Nguyen Hue Street, then walk to the adjacent Phu Hai Prison. The Tiger Cages at Camp 7 require a short Grab ride south of town. Entry to the main complex costs 30,000 VND ($1.20). Allow two hours minimum. The weight of the experience will stay with you for days, which is exactly how it should be.

Dat Doc Beach — The most beautiful beach on the main island, about 3km south of Con Son town via a road that cuts through national park forest. Completely undeveloped, calm water, excellent snorkelling off both headlands. There is a small parking area but no facilities — bring water, sunscreen, and lunch.

Bay Canh Island Turtle Watching — May through September, green sea turtles nest on Bay Canh Island’s eastern beach. The national park runs guided night watches that you register for at the park office (opposite the main market in Con Son town). Boat departs at 7:00 PM; turtle activity typically peaks between midnight and 2:00 AM. Cost is approximately 500,000 VND ($20) per person including the boat. Book a day ahead and arrive at the pier by 6:45 PM.

Diving and Snorkelling — Con Dao Dive Center and Rainbow Divers both operate professional operations here. Best visibility (15–30m) runs March through September. The diving around the national park islets features reef sharks, sea turtles, and hard coral formations that have remained largely intact because the park’s remote location limits the number of boats. A two-tank dive runs approximately 1,800,000–2,500,000 VND ($72–$100).

Hang Duong Cemetery — The resting place of Vietnamese national heroine Vo Thi Sau, who was executed by the French at age 19 for her resistance activities. The cemetery is a place of intense pilgrimage for Vietnamese visitors, and arriving on any weekend morning, you will find offerings and incense at virtually every grave. The scale of the cemetery — thousands of prisoners died on this island — is sobering. Free entry.

Motorbike Perimeter Circuit — Rent a motorbike for 120,000–150,000 VND ($5–$6) per day from any guesthouse in Con Son town and ride the full circuit of the island. The road passes through primary forest, climbs to ocean viewpoints, and drops through valleys where buffalo graze alongside the tarmac. Allow three to four hours including stops.

Where should you stay in Con Dao?

Budget: Con Son town guesthouses run 400,000–800,000 VND ($16–$32) per night for clean, simple rooms. The best budget option is staying on the main waterfront street (Ton Duc Thang) within walking distance of the market and restaurants.

Mid-range: The ATC Hotel and Con Dao Resort occupy solid mid-range positions at 1,500,000–3,000,000 VND ($60–$120) per night, with pools and proximity to town. These book out during Vietnamese holidays — reserve two to three weeks ahead.

Luxury: Six Senses Con Dao is one of the finest resort properties in Vietnam — beach villas directly on Dam Tre Bay, an extraordinary spa, and service that genuinely justifies the price at $500–$1,200 per night. Book three to six months ahead for peak dates.

Where should you eat in Con Dao?

• Con Son Market Stalls — The daily market in Con Son town has the best and cheapest food on the island. A seafood meal — grilled crab, steamed clams, fresh fish — for two costs 200,000–400,000 VND ($8–$16). The quality is excellent because the catch comes off boats that morning.
• Van Tao crab — A type of seaside crab unique to Con Dao, with sweet, delicate meat. Available at market stalls and local restaurants; ask specifically for “cua Van Tao” and pay 150,000–250,000 VND ($6–$10) per portion.
• Con Dao Resort Restaurant — For a more formal meal, the open-air restaurant at Con Dao Resort serves excellent Vietnamese and international dishes in a pleasant setting. Mains run 150,000–350,000 VND ($6–$14).
• Phi Yen Restaurant — The best local restaurant in Con Son town, serving seafood and Vietnamese dishes at honest prices. A full meal with drinks runs 200,000–350,000 VND ($8–$14) per person.

When is the best time to visit Con Dao?

March through July is the optimal window — seas are calm enough for diving and island boat trips, the turtle nesting season is active from May, and visibility in the national park waters is at its best. March and April see the best coral visibility (up to 30m on good days).

December through February brings heavier seas that can make Bay Canh Island boat trips impossible and limit diving. The island is much quieter and prices drop, but accept that some activities will be weather-dependent.

Vietnamese national holidays (April 30, September 2) see the island completely overrun — accommodation sells out weeks ahead and prices spike. Avoid these dates unless you book very early.

Con Dao is Vietnam’s most pristine island environment, and the historical significance of the prison complex adds a dimension of meaning that most beach destinations simply don’t have. It costs more than Phu Quoc or Nha Trang and requires more planning, but it offers something genuinely different.
