This is really quite a spectacular place. The chedi is certainly the highlight, but there's a lot more to see. The bell tower is beautiful (give the bell a few rings yourself), there's a lot of attractive sculpture, as well. I put this right up there with Wat Pho in Bangkok, Wat Doi Sutep near Chiang Mai and Wat Mahathat in Nakhon Si Tammarat as one of the most remarkable wats in Thailand.
