This was one of my favorite temples for its red coloring and the elephant statues. It is older than Angkor Wat and the construction materials include bricks. There were fewer visitors than in some of the other temples we visited.
As with the other temples, if you want to see the details and learn more about the history, you need to hire a guide. We were lucky to have Ratana (https://www.tripadvisor.com/Attraction_Review-g12591811-d13831714-Reviews-Angkor_Guide_Ratana-Svay_Dangkum_Siem_Reap_Siem_Reap_Province.html) recommended to us before our trip. We contacted him weeks before our trip to plan our visit. He got us to the best locations, explained everything and answered all of our questions in details.
