Getting to Banteay Chhmar from Angkor takes about four hours, maybe longer. And in Cambodia you need to be game for some adventure, or at least for some delays. But other ancient sites beyond Angkor can be reached more quickly.
The 12th-century temple complex of Beng Mealea lies about 1½ hours by road - a good road - east of Angkor. Being so close, it has some tourist bustle, but nothing like Angkor's.
The temple was built at roughly the same time as Angkor Wat and shares many of its style characteristics. Perhaps Beng Mealea was a trial lab for the better-known temple's style. Visit and you may wonder: If the ancient Khmers had Beng Mealea, why would they need Angkor Wat?
It's a mysterious maze of dark corridors and hidden chapels, of crumbling libraries and courtyards. For a true grasp of size, walk the temple's eastern causeway: You'll have to go nearly a kilometre, cross a moat and pass holy ponds before you come to steps and the remains of a platform that mark the temple's farthest limits.
Another site, Koh Ker, lies an hour and a half beyond Beng Mealea by a generally rough road. If you go, make sure you stop at the first bridge you come to, just a few hundred metres beyond Beng Mealea.
In the stream bed below is an ancient quarry; you can see the outlines of blocks of sandstone that were cut away, probably to be floated downstream to Beng Mealea.
Koh Ker is an area, not a single temple, that for centuries was a centre of provincial culture. In AD928, when its prince became King Jayavarman IV, the capital came to him, rather than vice versa, for reasons perhaps related to his feuding with the previous king.
Today Koh Ker has dozens of stone creations, some large and imposing, some small and intimate. The most spectacular is a complex that is three temples in one, including the Prang, the largest pyramid that Khmer architects built. Faced in sandstone, it has seven levels and stands about 35 metres high. This was Jayavarman IV's state temple.
From that complex, we drove a circuit through wooded land, coming to smaller but still remarkable temples every so often.
Prasat Krachap has many images of the god Shiva. Banteay Pichean has two brick towers standing in front of a collapsed central sanctuary.
At those places and others, I encountered only a guard who was posted there to prevent art theft.
Without question, the most spectacular of the Khmer monuments outside Angkor is Preah Vihear, built atop a 518m cliff.
The visitor ascends a long stone-paved avenue, arriving at ever-larger holy buildings. At the top is the main sanctuary and, a few steps beyond, a jaw-dropping view of Cambodian countryside.
But for now, Preah Vihear is best left off your schedule.At the border with Thailand, it has been the scene of a military stand-off between the two countries' soldiers since last year.
The more comfortable and common way to reach the temple, assuming the border is open, is from Thailand. Thai tour companies can make the arrangements.
