My partner and I visited the Ancient City on our last day in Bangkok and found that it was not worth the journey and relatively steep entry fee. The city itself is sited a fair distance away from the city centre (we took a twenty-minute taxi ride from the end of the BTS rail line), and the buildings themselves in the city are not originals. The city is undeniably beautiful and educational, with an audio guide telling you more about each of the replica buildings (copies of buildings from around the country). However, as we personally are more interested in landscapes and seeing originals, rather than a curated, at times gimmicky set up, we were not terribly impressed.
Nonetheless, a nice morning out cycling around a pretty site. Which we would not have paid the same amount for again.More
