Thailand offers quite a few airports servicing the international flights: 2 in Bangkok (Suvarnabhumi and Don Mueang Airports), Phuket International Airport, Chiangmai International Airport, Hat Yai International Airport, Samui International Airport, and Krabi International Airport.

There are also several land borders waiting for tourists traveling by local transportation (minivans/buses, etc.). Thailand has over twenty international overland border crossings. These allow overland travel from Malaysia (seven passes, the most popular ones are the Padang Besar and Sadao crossings), Burma (four crossings, the most popular ones are Ranong/Kawthaung), Laos (six crossings, the most popular ones are Nong Khai/Vientiane and Chiang Khong/Huay Xai, though Nakhon Phanom/Tha Khaek and Mukdahan/Savannakhet are also widely used) and Cambodia (six crossings, Aranyprathet/Poipet is the most popular, followed by Had Lek/Koh Kong).

A long coastline along the Gulf of Thailand (1,875 km) and the Andaman Sea (740 km) (not including the shores of some 400 islands, most of them in the Andaman Sea) makes Thailand accessible also for sailors and sailing boats.
