ATV or quad bike is a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. ATVs are designed to handle a wider variety of terrain than most other vehicles, such as beaches, rivers, creeks, country roads and even desert. ATVs are already popular in western countries and now they’ve arrived in Koh Tao as the island’s newest and most exciting outdoor activity.
