I got picked up at 4:30, and it takes about an hour and a half to get from your hotel door to the actual temple of Angkor Wat. The tuk-tuk drove me out to Angkor, which is a little way outside of Siem Reap. Then after buying tickets to the park, we drove some more to the area outside of the temple. Then I walked in the dark for a little while, in a swarm of tourists, into the yard in front of the temple. If your goal is to be there for sunrise, arrange your tuk-tuk a few days in advance. I organized mine with the owner of my guesthouse, but you can also schedule a pick up from a tuk-tuk driver you’ve already been working with. You can also schedule a guide and car, or you can even take a specific photography tour.
