You can see a 140-foot-long reclining Buddha, traipse through the nested quarters of the gilded Grand Palace, temple-hop from ancient wat to ancient wat, haggle at the happening 8,000-plus-stalls Chatuchak Weekend Market, maybe even catch a water-taxi down the Chao Phraya River to a floating market. There's Muay Thai kickboxing to watch, spicy Thai curries to tuck into, and go-go bars in the Soi Cowboy red-light district where you (this one's for all the single guys out there!) can literally let yourself go.
