"The ancient city, Muang Boran, is a reflection of Thailand's multifaceted ancient culture presented in an authentic and visually exciting setting." These are the words on the brochure you get at the entrance to this fantastic park. I spent a whole day here with my friend and her sister, and there is plenty to see. There are 109 monuments (in summer 2001) from all over the country.
If you can't spend several months traveling in the country to see all the beautiful buildings, you definitely should go here to see the continuity of the history, arts, cultures, religions, thoughts, as well as the beliefs of Thai talents.
In the picture you see a restaurant in the floating market. We ate dinner here, and surprisingly, prices here are the same as downtown. There's no need to bring your own food unless you do not like traditional Thai food. I like it because it's tasty and spicy.
Going here is a good one-day trip from central Bangkok, so if you are staying there, my advice is that you spend a day here.
