Rolous Group consist of three of the earliest temples in this area; Preah Ko, Bakong and Lolei.
Started on tuk-tuk at 0630 and took us half an hour to reach Bakong. On the way we passed by some very busy morning markets. It's interesting, but the highway was very dusty. It's advisable to bring along a surgical mask or two.
The three temples were very quiet, in fact there were only two other tourists. Bakong is the biggest, the moat and greens before the entrance make a peaceful view in the early morning. Bakong requires quite a climb to the main temple at the top. From there it offers an amazing view.
We then backtrack to Preah Ko on the way back to the highway. Preah Ko has a very open concept, due to the destroyed walls and surrounding buildings. Check out the three kneeling bulls facing the steps up the platform where the six main towers are on.
Lastly, we went to Lolei, which was under heavy restoration. There are four red brick towers similar to those at Preah Ko. You can actually skip this if you are pressed for time. However, along the way to Lolei, you can see some green paddy fields that offer much tranquility.
It's a nice place to visit as the journey itself is pretty interesting, and you can enjoy the quiet and peace as there are not many tourists around. If you only have the one-day pass, you can skip this. If you have the three-day pass, you can visit here, and then move on to Beng Mealea (which has a US5 fee) and a nearby Floating Market.
