Songkran, the Thai New Year, takes over Bangkok from Tuesday 13 to Thursday 15 April 2027, three fixed national holidays of merit making in the morning and citywide water fights by afternoon. Khao San Road is the backpacker centerpiece, but no street in the old town stays dry for long.
The dates are fixed holidays, 13 to 15 April, in the Bank of Thailand 2027 holiday list, so this is a trip you can book around with confidence.

What is happening
Songkran is the Thai New Year, and in Bangkok it runs on the fixed national holidays from 13 to 15 April 2027. The guide frames the same window plainly: March to May is the hot season, with the Songkran water festival on 13 to 15 April as the glorious exception. April is the peak of the heat, and the water is the point.
Khao San Road is the backpacker centerpiece of the celebrations, and the old town around it is the natural base: the Grand Palace, Wat Pho and the river piers are all in the same district. Stay near it if the festival is the trip, and accept the terms: you will be soaked within minutes of stepping out, and so will anything you carry.
Plan like a local for three days. The guide packing list carries a dry bag for Songkran and boat days: use it, and leave everything that cannot get wet at the hotel. Do the temple mornings early, and let the afternoons belong to the water. For the music side of the same week, read the sibling post on the SIAM Songkran Music Festival, which runs 10 to 13 April at Bravo BKK RCA.
Getting there after you land
Fly into Suvarnabhumi, BKK, about 30 km east of the center; Don Mueang, DMK, about 25 km north, takes most low cost and domestic flights, so check which airport your ticket uses. From BKK the Airport Rail Link runs from the basement level to Phaya Thai, roughly 05:30 to midnight and immune to traffic, which matters in a holiday week. See our Suvarnabhumi to the city center transfer guide for every option, priced and compared.
Airport Rail LinkCheapest
From the basement level at BKK to Phaya Thai, immune to Bangkok traffic and to holiday road closures.
Metered taxi
From the official kiosk on Level 1 at BKK to your door; add the ฿50 airport surcharge and about ฿75 of expressway tolls.
A1 bus (from DMK)
If you land at Don Mueang instead, the A1 runs to Mo Chit BTS and Chatuchak; the A2 runs to Victory Monument for the same fare.
Pre-booked transfer
A fixed fare Kiwitaxi pickup, or a Welcome Pickups driver meeting you in arrivals; the zero decision option for a late landing.

The full first hour: Bangkok guide
The ride in, the first ticket and the first meal, plus where to stay in Bangkok.
Where to stay, and getting back
For Budget and for the festival itself, Here Hostel Bangkok, on Ratchadamnoen Klang Road, is the guide pick in the old town: curtained dorm bunks, private rooms, a pool and a garden bar, ten minutes walk from Khao San Road and an easy stroll to the Grand Palace. For Mid-range, AriyasomVilla, at 65 Sukhumvit Soi 1, is a 1942 family villa turned 24 room boutique in frangipani gardens, the calmest sleep in downtown Bangkok, with Ploen Chit BTS eight minutes walk away. For a Splurge, Mandarin Oriental Bangkok, at 48 Oriental Avenue in Bang Rak, opened in 1876, brings Chao Phraya river views and shuttle boats to the Skytrain.
Base in the old town for Songkran and the river and rail do the rest. For getting back, the Airport Rail Link to BKK skips the holiday traffic entirely.


The first hour, sorted
Get connected before you land: the guide names an Airalo eSIM for Bangkok, with Saily as the alternative, because you need data from minute one for the arrival card QR code, Grab rides, rail maps and translation. Complete the free Thailand Digital Arrival Card online in the three days before you arrive and screenshot the QR code.
Then sort cash. Cards work in malls, hotels and bigger restaurants, but street food, markets, temples and tuk tuks run on cash, and every Thai ATM charges a flat ฿220 on foreign cards, so withdraw larger amounts less often. Tap water is not safe to drink; bottled water is cheap everywhere, and restaurant ice is factory made and safe.
For a first meal, the guide points to pad thai or a tom yum, or a mango sticky rice from the nearest market stall: sweet coconut rice, ripe mango, zero decisions, and April is mango season. Book the Grand Palace for your first morning, arrive at the 8:30 am opening, and dress for the strict code: shoulders and knees covered, no exceptions.
