You have to do this one! It's part of the Angkor Thom area, so it's included with the Angkor ticket. Give yourself maybe half an hour (?) to walk up the hill. There is at least one small temple to see (from a distance) along the way, and there are places to stop to sit if you want. Once you reach the top of the hill, climbing the temple takes no time at all. Go for sunset, the view is spectacular!! But get there with plenty of time to get a good viewing spot, lots and lots of people are up there with you. Gorgeous, and a photo op you do NOT want to miss.

This was last stop on full day tour. We hiked to the top which takes about 15-20 minutes. Two platforms on way up for viewing. Temple up top is open to climb, mist crowd up here for sunsets. The views here are great, full view of Angkor Wat in the distance was nice and great photos! We enjoyed the site, stayed for sunset which was great. We actually moved down during sunset to get photos at lower two platforms. Very good views and pics from there as well.

All reviews are right, once again: Sunsets from the top of the pyramid are spectacular, but because of that, they are a mass event - can't be helped. Still worth it, and if you're tall, you can still make great pix. Zoom pix of Angkor Wat (on the other side of the sunset) are spectacular too but these days, they just look like drone shots. I think it's one of the best sunset spots in SR and I would recommend.
