If you are planning to visit Thailand, I am sure that at least one of these 3 big cities: Bangkok, Chiang Mai, and Phuket must be your destinations.
If you do not have time to visit all three cities and ask me for the best city to visit in Thailand, I would say it depends on your personal preference; these 3 cities are different.
In this post, I intend to tell you the overview information of Bangkok, Chiang Mai, and Phuket. I hope it help you decide the place to visit in Thailand.
Bangkok: Bangkok is a capital city of Thailand and is located in central Thailand. For me, Bangkok is a great city for historical sites such as The Grand Palace, Wat Phra Kaew, Wat Pho, and Wat Arun. Besides, it is a great city for shopping. You can expect to see several huge and luxury malls such as Siam Paragon, Central World, The Emquartier where you can buy international brands and also markets such as Chatuchak Weekend Market, Pratunam Market where you can buy cheap goods and have fun with bargaining. For beautiful natural places such as beaches, caves, mountains, forests, and waterfalls, I do recommend you to go out of Bangkok.
Chiang Mai: Chiang Mai is a biggest city in northern Thailand. For me, it is like a capital city of northern Thailand. When talking about Chiang Mai, I am thinking of mountains, hill tribes, and unique culture. Chiang Mai is a popular destination for both locals and tourists. Locals love going to this city in cool season (November to February). This city has many things to see, but it is not crowded or busy like Bangkok. I went to Chiang Mai several times and did trekking once at Doi Mon Jong. If you are a mountain lover, check the link out; you might want to go there.
Phuket: Phuket is the biggest island in Thailand and located in the Andaman Sea of southern Thailand. It consists of several small islands. When talking about Phuket, I am thinking of white sand beaches, islands, and the seas. Same as Chiang Mai, this city is popular for both locals and tourists. Locals usually go to Phuket during summer (March-May).
