Rules in force · 6Drug trafficking can carry the death penalty in Singapore…

Southeast Asia ↗Drug trafficking can carry the death penalty in Singapore, Malaysia, Indonesia, Vietnam, Laos, Thailand, Brunei and Myanmar; never carry a bag or parcel for anyone.
Southeast Asia ↗Carry a passport valid for at least six months from entry with two blank pages; airlines refuse boarding on less.
Thailand ↗Check entry rules and any arrival card on the official Thai government sites for your passport; visa-exempt stays and pre-arrival forms change.
Thailand ↗Do not criticise or mock the monarchy: insulting the royal family is a criminal offence.
Thailand ↗Temples and palaces: shoulders and knees covered, shoes off before entering halls.
Thailand ↗E-cigarettes and vapes are illegal to import or use; do not pack them.

Eastern Thailand is the Gulf coast closest to Bangkok: Pattaya, Rayong, Chanthaburi, Trat and the islands of Ko Samet and Ko Chang. It is the short-haul beach option when you have 3–5 days and do not want to fly south. The trade-off is that Ko Samet and Ko Chang are the developed islands; the smaller Trat islands are harder to reach and quieter.

Plan the nights

How to split the nights, day-trips and what to do with your bags

Open Plan the nightsClose Plan the nights3 partsNights · Day-trips · Bags

Night sequences

3 nights: Pattaya or Ko Samet 3 nights from Bangkok
5 nights: Ko Samet 2 + Ko Chang 3, or Ko Chang 4 with a Trat day
7 nights: Pattaya 2 + Ko Chang 4 + Trat 1

Do not plan a same-day Bangkok arrival and Ko Chang ferry; the transfer plus boat takes most of a day.
Border areas near Cambodia had skirmishes in 2025; check official advice before crossing at Aranyaprathet.

Day-trips door to door

To	From	Door-to-door p50	Last return	Note
Ko Samet	Bangkok	210 min	check	Bus or minivan to Ban Phe, then a short ferry; allow half a day each way.
Ko Chang	Bangkok	330 min	check	Road transfer plus ferry runs longer than 5 h 30; allow most of a day and do not book a same-day boat after a late arrival.
Pattaya	Bangkok	120 min	check	Frequent buses and minivans; the easiest eastern leg.

Bags between cities

Most hotels on Ko Samet and Ko Chang do not offer luggage forwarding; carry your bags on the ferry.

Eastern Gulf Coast: The Gulf side takes most of its rain from May to October; November to February is the drier, cooler window and the peak for island beds.

Treat November to February as the dry window, but keep one spare day in the plan: rough weather can cancel island crossings.

Door-to-door p50, 2026 estimate

From	To	How	p50	Note
Bangkok (Suvarnabhumi or Don Mueang)	Pattaya	Bus or minivan	~2 h	Buses leave from both airports and Ekkamai; the cheapest and most frequent option.
Bangkok	Ko Samet (Ban Phe pier)	Bus or minivan + ferry	~3 h 30–4 h door	Ferries run from Ban Phe; confirm the last departure at the pier, as it varies by operator and season.
Bangkok	Ko Chang (Trat)	Bus or minivan + ferry	~6 h door	Long transfer; an overnight in Trat is the safer plan if you arrive late.
U-Tapao (UTP)	Pattaya / Rayong	Taxi or shuttle	~30–45 min	Small airport between Sattahip and Rayong; limited flights, check schedules.

Dish	Where	Timing / trap
Seafood	Rayong, Chanthaburi, Ko Chang	Grilled fish and prawns are the local staple; prices are lower than the Andaman coast.
Chanthaburi fruit	Chanthaburi	Durian and mangosteen peak in the hot season; roadside stalls sell by the kilo.
