Angkor Wat is the biggest of all of the temples and is one of the ‘big three’ temples alongside Angkor Thom and Ta Prohm. I understand it to be the largest religious monument in the world. This is a must see as are all of the Angkor temples which are breathtakingly beautiful. I watched the sun rise over the stunning Angkor Wat while sipping champagne. It doesn’t get much better than that!
