Destination & City Travel Guide
About Bangkok
Bangkok is best explored by pairing nearby places and leaving travel time between districts. The Grand Palace and Wat Pho make one riverside day; Chinatown works well for an evening; and the Jim Thompson House brings a different museum setting near the city centre. Boats on the Chao Phraya River can be useful transport as well as a way to see the banks. Suvarnabhumi Airport has an Airport Rail Link to Phaya Thai, where travellers can connect with the urban network.
Read more about Bangkok
Tips for travellers from India
Phaya Thai is convenient for an airport-rail arrival, while a riverside hotel works better for repeated visits around Wat Pho and the Grand Palace. Sukhumvit offers a different base focused on shopping and the urban railway. From Suvarnabhumi, the Airport Rail Link terminates at Phaya Thai, where a separate BTS connection continues towards other districts; Makkasan is another interchange option for the MRT. Keep the airport ticket distinct from tickets for the city networks.
The Grand Palace requires clothing that covers shoulders and legs; its entry rules are stricter than those of a shopping centre, so choose the day’s clothing for the palace itself. Wat Pho and a river crossing to Wat Arun make a coherent old-city route. The Jim Thompson House fits better with the Siam area than between those temple visits. In September 2025, Central Park shopping centre opened beside Lumpini Park, giving the Silom area another dining stop after a park walk. Songkran falls in April and can turn central roads into water-festival zones, particularly around Silom. If the boarding pass points to the SAT-1 satellite at Suvarnabhumi, follow the airport’s automated people-mover signs after departure formalities rather than seeking a separate roadside terminal entrance.
Best time to visit Bangkok
November to February, usually about 21–32°C, with less oppressive heat.

Airport Information & Terminals
ULN: Ulaanbaatar airport. Airport access in Ulaanbaatar depends on arrival time, terminal, hotel location and local traffic. Confirm the airport name on the ticket, then choose between official taxi, app cab, airport bus, rail or hotel transfer based on luggage and time of day.
BKK: Bangkok airport system. Bangkok may involve Suvarnabhumi or Don Mueang. The two airports are far apart, so never book a tight self-transfer without checking which airport each flight uses.
