The place could be awesome - if people took care of it. Entrance fee is too high ($20) given all the trash everywhere and even the water in the waterfall is dirty...I hope it gets better in the future!
Town known for its temples. Not much to do except for amazing Night Market - there's a wide variety of food from super spicy to sweet and you can try all in low prices. Ayutthaya is also a weekend runaway town from Bangkok.
