Chiang Mai has a tropical climate with warm weather year-round and—thanks to its higher elevation—cooler nights. The best time to travel is between December and February, when the rainy season is over. You can travel to Chiang Mai by bus or train but the most reliable and fastest way is by plane. Chiang Mai International Airport is well connected to many Asian countries. A visa-on-arrival is delivered at the airport for 30 days, depending on your nationality. The language is Thai but most people speak some English. The currency is the Thai baht. Thailand is a constitutional monarchy and the King is revered. Avoid discussing the royal family and be respectful when entering temples. Electricity is 220 volts, so plan accordingly.
