If you start your visit at the northern end of the hill, where there is a cluster of trinket shops, you can climb the hill by a steep stairway with 509 steps which will lead you to the newest addition to Phnom Udong: a glitzy modern temple home to a famous Buddha relic (some bones and a tooth), previously housed in a shrine in Phnom Penh in front of the railway station. This temple is a recent construction, but the panoramic sight from this location is spectacular.
From there you can take a path that runs along the ridge allowing you to visit each of the sites. First, it will take you along three stupas for former kings. The first one houses the remains of King Soryopor. The second one is inhabited by the corpse of King Norodom’s father King Ang Duong with four bayon style faces at the top. South again lies Chedi Mouk Pruhm, a bland concrete building holding the remains of King Monivong.Next come a series of small chapel-like temples, one holding a replica of a statue of a holy cow. The original statue was lead off by the Siamese after they sacked the area and taken to Siam.Conclude the tour with a visit to the "Vihear of the 18-Cubit Buddha" which was badly damaged during the war and whose large Buddha image was blown up by the Khmer Rouge in 1977. All that remains of the Buddha is his lap and right torso and shoulder. Also two rows of tall pillars which would have held a very high ceiling still remain.
At the base of the ridge is a memorial to victims of Pol Pot, containing the bones of people buried in the 100 or so mass graves found in the area.
After the visit, take a lunch at one of the shaded stalls at the foot of the mountain. You can bring your own pick-nick as most Cambodians would do. After lunch, take a rest for the hottest part of the day
