Phnom Bakheng is one of the temple you can visit in the small tour.
Here is an extract from Wikipedia:
“…Phnom Bakheng at Angkor, Cambodia, is a Hindu temple in the form of a temple mountain. Dedicated to Shiva, it was built at the end of the 9th century, during the reign of King Yasovarman (889-910 A.D.). Located atop a hill, it is nowadays a popular tourist spot for sunset views of the much bigger temple Angkor Wat, which lies amid the jungle about 1.5 km to the southeast. The large number of visitors makes Phnom Bakheng one of the most threatened monuments of Angkor...”
