I've decided to do a little housekeeping to keep track of the provinces I have visited in Thailand. The country has 76 provinces, plus Bangkok, which is an administrative district, not a province, like the District of Columbia in the US. I have visited 33 of the provinces, plus Bangkok. In addition, the country is divided into five regions: the Central, Eastern, Northern, Northeastern and Southern regions. So I've decided to list the provinces I've visited by region, alphabetically for easy look-up, within each region. After that I have listed the provinces by region that I have not yet visited (43). [33 + 43 = 76]
Update 28 December 2015
In December 2015 our travels took us to ten new provinces: Chaiyaphum, Kalasin, Khon Kaen, Loei, Maha Sarakham, Nong Bua Lam Phu, Petchabun, Phitsanulok, Udon Thani and Uttaradit. We have updated the listings of the provinces below and our new totals are 43 provinces visited and 33 provinces not yet visited. So we have now been to more than half of the provinces. [43 + 33 = 76]
Update 11 January 2016
In January 2016, we discovered the excellent Thailand Photo Gallery by Leslie R. Wilk, which sorts images by province and displays them in slideshows that run automatically. Choose a province and sit back and enjoy great photos of many of the destinations in that part of the country. Wilk has prepared galleries for Bangkok and 45 of the provinces. I have integrated these galleries into the listings below. The link in the names below go to those Wilk photo galleries. Enjoy great images of many parts of Thailand. No extra charge. Of course Leslie R. Wilk owns the copyright to all the pictures in these galleries.
