As you'll notice pretty quickly, Chiang Mai's main transport is motorbikes. It's easy to rent, no driving license required.
<aside> ⚠️ Please beware of the risks in driving your own motorbike! Always wear a helmet, don't drink and drive, don't smoke 🌿 and drive. Accidents can happen even to the most experienced.
