Muang Boran is located in Samut Prakan province (in the outskirts of Bangkok). It has been ranked the biggest open-air (private) museum in the world. It has the shape of Thailand and inside its huge park, you can discover the greatest architectural treasures of Thailand's various regions (models/reconstructions/typical houses), admire the old wooden stilt houses by the water, and plunge into the past when the traditional life by the water was the essence of the Thai village.
Luckily, it was a lovely cool day on Saturday, so it was perfect for wandering/cycling around the huge site.
First of all, don't forget to buy your tickets. Foreigners pay B300 and Thais pay B100. GoW paid. Her bike was also cheaper, but as she paid for that too, who am I to complain?
