After arriving in Duong Dong, head first to Dinh Cậu Temple on the waterfront. The small shrine sits dramatically on black rocks above the sea, beside the town’s familiar lighthouse, and is best treated as a quick atmospheric stop rather than a formal temple tour—allow about 45 minutes. Dress modestly, remove shoes before entering the shrine, and take care on the uneven rocks, especially if the surface is wet. A short taxi or Grab ride from most Duong Dong hotels usually costs around 50,000–100,000 VND; the waterfront is also easy to reach on foot from central accommodation.
Walk or take a very short ride inland to Duong Dong Market, where the morning trading is liveliest but food stalls generally continue through lunchtime. Browse the fruit, herbs, dried seafood, and pepper products, then keep lunch light with noodles, grilled seafood, or bánh canh from a busy vendor—roughly 40,000–120,000 VND per person. Afterward, continue south to Long Beach by taxi or Grab, normally 10–15 minutes and about 60,000–120,000 VND. Settle into a beach chair for the afternoon, swim when the water is calm, and keep valuables secured; September can bring brief showers, so a waterproof bag is useful. Beach chairs and umbrellas commonly cost around 50,000–150,000 VND, depending on the section and whether you order drinks.
Stay at Long Beach for sunset, then make your way to Xin Chao Seafood Restaurant on the Duong Dong waterfront—allow 10–15 minutes by taxi or Grab, or longer if walking from the southern beach area. Arrive around 5:30–6:00pm for the best chance of a table with a view; the restaurant typically operates into the evening, but hours can vary seasonally. Order a few dishes to share—local prawns, squid, clams, or grilled fish—budgeting approximately 250,000–500,000 VND per person. September evenings can be breezy and rainy, so choose a covered table and confirm the seafood’s price by weight before ordering.
Leave Duong Dong around 7:00–7:30am by private taxi or Grab car on ĐT45; the drive to Ganh Dau takes roughly 35–45 minutes and usually costs 350,000–550,000 VND. Ask the driver to drop you near Ganh Dau Cape, where a short walk leads to the rugged northwest shoreline. Spend about an hour following the coastal paths, looking across the Gulf of Thailand toward Cambodia and watching the fishing boats come in. There is little shade and no reliable refreshment stop right on the cape, so bring water, sunscreen, and shoes with a good grip; after rain, the rocks can be slippery.
From the cape, continue a few minutes by car or motorbike to Nguyen Trung Truc Temple, a small, atmospheric coastal shrine dedicated to the Vietnamese resistance hero. Allow around 45 minutes to look around respectfully and enjoy the sea views. Dress modestly—shoulders and knees covered is appreciated—and keep in mind that opening hours can be informal, generally from early morning until late afternoon. For a simple early lunch or iced coffee before the park, ask your driver about local seafood restaurants around Ganh Dau Market; grilled squid, crab, and steamed shellfish are usually better value here than at the major resort complexes.
Continue south along the coast to VinWonders Phu Quoc in Bai Dai, normally another 10–15 minutes by car. Plan on four to five hours here, with the water attractions and indoor areas especially useful if the September heat turns intense. Entry prices vary by date and ticket type, but budget approximately 950,000–1,350,000 VND per adult; check the official ticket page before leaving, as water rides, shows, and operating hours can change. Lockers, towels, and food inside are additional, so carry only essentials and use the park map to group rides rather than crossing the grounds repeatedly. When you are ready to leave, a short taxi or shuttle transfer brings you to Grand World Phu Quoc for the evening: wander the canal-front streets and brightly lit entertainment zone for about two hours, then choose a casual Vietnamese or seafood restaurant for dinner, allowing roughly 200,000–400,000 VND per person. It is liveliest after sunset; arrange your return to Duong Dong in advance, since app-based cars can be slower to find late at night.
Leave Ganh Dau around 6:30–7:00am for An Thoi; the southbound drive takes roughly 1 hour 20 minutes to 1 hour 45 minutes, so arrange a private taxi or Grab in advance. Ask to be dropped at An Thoi Cable Car Station, where there is ample parking and a large terminal with ticket counters, cafés, and toilets. Check the operating schedule before leaving—service can be weather-dependent, and September showers or strong winds may cause delays. The cable-car ride to Hon Thom takes about 15–20 minutes each way and gives you excellent views over the scattered southern islands; allow around two hours including the terminal and transfers.
On Hon Thom, spend the next two to three hours taking it slowly: walk along the beach, swim if conditions are calm, or use the island’s water-activity facilities if they are operating. Facilities are spread out, so wear sandals and bring sun protection; lockers and food outlets are available, though prices are generally higher than on the mainland. Return to An Thoi around lunchtime and take a taxi or Grab south along the coastal road for approximately 20–25 minutes to Sao Beach. Choose a simple beachfront restaurant for lunch, then settle into the shade for a relaxed swim and a couple of hours on the famously pale sand. September can bring rougher water and seaweed, so check the swimming area before going far from shore.
From Sao Beach, continue north for about 25–30 minutes to Ho Quoc Pagoda in Duong To, ideally arriving around 4:00pm when the heat begins to ease. The mountainside temple is free to enter and rewards you with broad views across the Gulf of Thailand; dress modestly, remove shoes where requested, and avoid loud conversation during prayers. Afterward, allow roughly 20 minutes to reach Ra Khoi Restaurant in An Thoi for dinner. Order local seafood to share—typically about 250,000–500,000 VND per person—and confirm the price and weight of live seafood before it is cooked. Keep the evening unhurried, but arrange your return taxi early if you are heading back north, as Grab availability around the harbor can thin out later at night.
Start in An Thoi with the short drive north to Suoi Tranh Waterfall in Duong To, usually around 25–35 minutes by taxi or motorbike depending on traffic. Aim to arrive around 7:30–8:00am, before the heat builds; the entrance fee is typically about 30,000–50,000 VND. Allow roughly 1.5 hours for the shaded forest path, but set expectations realistically: the waterfall is seasonal and can be little more than a trickle in the dry months. Wear shoes with grip, bring mosquito repellent, and avoid climbing onto wet rocks around the pools.
Continue south toward Phu Quoc Prison in Cay Dua, near An Thoi, allowing about 30–40 minutes on the main road. This is a quiet, sobering visit rather than a light sightseeing stop: the reconstructed cells, barbed-wire enclosures, and wartime exhibits are best taken slowly, and an hour is sufficient. It generally opens around 8:00am–5:00pm, often with a midday break, and admission is usually free or nominal. Dress respectfully and bring water, as parts of the grounds are exposed.
After the prison, take a taxi or Grab north along the main south–central road to Ham Ninh Fishing Village, roughly 30–40 minutes. Have lunch at one of the simple seafood restaurants along the waterfront—ask for local crab, grilled prawns, or steamed shellfish priced by weight before ordering. Spend about 1.5 hours wandering the pier and shoreline; it is more enjoyable as an unhurried working village than as a polished attraction, and the water can be muddy at low tide. From Ham Ninh, allow 25–35 minutes back toward Duong Dong; a private car is easiest if you are carrying seafood or traveling in the afternoon heat.
Finish at Rory’s Beach Bar for a relaxed beachfront drink and sunset atmosphere, allowing around two hours. Budget approximately 150,000–300,000 VND per person for drinks and a snack, and check the venue’s current opening hours before setting out, as seasonal schedules can change. Arrive before sunset for a table by the water; a taxi or Grab back into central Duong Dong is usually the simplest option afterward, especially if you have been drinking.
