Wat Bakong is part of the Roluos Group some 13 kilometers away from the Siem Reap town center. If you want to reach Wat Bakong before the sunrise by tuktuk, you have to leave your hotel around 5:00 AM. It would take you about 30-40 minutes to get there from Siem Reap. It may be still dark if you get there, so be sure you have a flashlight or any light source with you so you can navigate across the causeway over the moat safely and to the top of Wat Bakong. Go up all the way to the main tower, sit there, and wait for the sun to rise. Chances are, you will be alone for the whole duration of your stay if you arrive to view the sunrise. So, enjoy it as it only happens seldom.
If you're satisfied with viewing the sunrise, don't leave just yet. Go west of the temple and take wonderful silhouette shots. The temple is just almost perfectly symmetrical and its silhouette is just amazingly unique. Even with its age, the temple is largely complete. As for the carvings and lintels, most of it is in bad state and some are just replicas of the original. However, the level of craftsmanship of the intact ones is still admirable as with other carvings and lintels at other Angkor sites.
Go to Wat Bakong if you don't like the hustle and bustle and the noise from the tourists experienced at the other temples. Best if you go to Wat Bakong early in the morning to view the sunrise. Couple it also with going around the Roluos Group. You are sure to have a maximum of a couple of tourists sharing the sites with you.
