I remember this temple quite clearly. However from my journal and guidebook I'm unable to definitively identify it. I visited it on my third day. This was the day we did a lot of moto riding but were still inside the main park. It is definitely not the Bakong which is bigger and by the time I got there the weather had changed for the worse. It probably is Preah Ko or some other small temple we stopped at along the way.
The reason this photo is in this gallery and not say one from the Bayon is I liked the contrast with the pink flowers against all the stone. Plus the sky is nice and blue. This temple was not popular so I could take my time setting up photos without having to worry about other people ruining my shot.
