Angkor Wat is one of the most breathtaking sites I have ever visited and as a wonder of this world it trully is. Set in its own reservation with over 20 other temples (not as big or as slpendid). But worthy of a mention is Angkor Thom, a walled city with spledors within and temples you are still actually allowed to climb and explore without a guide. So get there while you can, still touch, climb and actually feel the real magic and beauty of this great site.
