Supattra grew up in Northern Thailand and of course we've visited a lot of the great destinations in the North. Here is an article that highlights ten of the most popular spots in the North, all of which we have visited and we will surely take you to see some of them, while you are in Thailand too. Let us know if there are some that especially appeal to you.
The family home is in the mountains above Lampang, which is the area where Supattra grew up and an area where people have lived for more than 1,000 years. Lampang is the only city in Thailand that still offers horse and buggy rides around the town, which is a lot of fun. If you'd like to take one of those rides, we will surely do it. It is much more relaxing than a Tuk-Tuk ride in Bangkok. If you read the Wikipedia article on Lampang, you'll learn that the area was at the heart of the Lanna Kingdom, subject to Burmese control, until the natives rose up against the Burmese rulers and became a part of Siam during the reign of the great Thai King, Rama V.
