You will need a temple pass (1 or 3 days), which you can purchase online or have your guide take you to the ticket office before the tour begins. With occasional food and rest breaks, visit Angkor Wat, Angkor Thom, Bayon Temple, and Tah Prohm. Walk around and inside each temple, with information from your guide, so you will understand what you see. After your entry fee, it only makes sense to pay a little more for a registered guide, so that you're not simply looking at the stones. Get a feel for the 12th-century Khmer empire and stand amongst the magnificent monuments of Angkor Wat, the largest religious structure in the world; educate yourself in a most enjoyable way. Know the rich history from one of the most enduring architectural achievements ever. Admire the stone figures that greet you at the southern gates of Angkor Thom and stroll towards the Bayon Temple to see the etchings of smiling faces at its central peak. Visit the Terrace of the Leper King and the Terrace of the Elephants. At Tah Prohm, soak up the atmospheric combination of trees growing out of the ruins and the jungle surroundings and last of the day visit, steps to the temple of Phnom Bakheng to sunset.
