This is certainly a unique Buddhist temple, completely different from all others you have already seen while visiting Luang Prabang. It dates from the 14th century and its architectural style is mainly Vietnamese (although with Lao and Thai characteristics too). No wonder that it is frequented mainly by Vietnamese expats living in Luang Prabang. Organize yourself to be at "Wat Phra Baht Tai" at late afternoon. Visit the ordination hall (the sacred "Sim"), the reclining Buddha statue, the funerary stupas and then, via a stairway which starts in front of the ordination hall, reach the grotto where the famous Buddha's footprint is kept (the footprint itself is an artificial construction common to Buddhist temples in Laos and Thailand, although this one is considered more realistic than most). There is another "huge" Buddha's footprint that was found in the temple's grounds and can also be visited. After it, keep going down the steps leading to the Mekong River. Right there, from a small balcony, listening to the chants performed by the monastery's monks and novices, enjoy the awesome views of the iconic Mekong river and its sunset. Enjoy!
