FAQ

Which Thai island should I choose for a first holiday?

So far we have covered Phuket in depth: Thailand's largest island, with an international airport, beaches for every taste and day trips to the islands and the mainland. Thailand's tourism ministry counted 14.2 million visits to Phuket in 2025. Other regions will be added as we verify them.

What is the best time to visit Phuket?

December to April for the sea and island trips. By TMD normals January, February and March are the driest (24-81 mm of rain), and September and October the wettest (336-350 mm). Temperatures barely change, with monthly means of 27.6-29.6 °C.

How much does a holiday in Phuket cost?

We do not publish an average budget until we have our own dated price checks. Fixed costs are known: a national park fee of THB 300-500 per foreign adult under the DNP table, and THB 100 for the Smart Bus from the airport. Rooms are cheapest in low season, when hotel occupancy in September 2025 was 66% against 86% in January.

Which islands near Phuket are worth it?

For half a day, the nearby Coral, Racha and Khai islands are outside national parks, with no park fee and no seasonal closure. For a full day, Phi Phi (THB 400 fee) and the Similans (THB 500, open 15 October to 15 May). Our islands page compares them in one table.

Is it safe to buy tours from street stalls?

It can be, but check what the price includes, who runs the trip and whether the park fee is included. Common tricks with tours and passport deposits are covered in our scams guide. If you are cheated, call the tourist police on 1155.

Is Phuket worth visiting in the rainy season?

Yes, if you can live with downpours and waves on the west coast. It rains on 19-23 days a month on average, but showers alternate with sunshine. Never swim under a red flag, and look for calmer bays on the east coast.
