Cambodia's treasure of ancient temples goes beyond the group at Angkor. The mystical temple of Beng Mealea is one of those. Built in the Angkorian period, 40 km from Angkor Wat on an ancient royal highway, it was among the biggest temples. Today, it is a magical ruin that has been hidden under the jungle carpet until recently. Giant serpent-like roots are slowly crushing the walls, while a web of smaller roots are holding the place together. You have to crawl over fine carved sandstone blocks, duck under fallen pillars, and hang in vines to get through the giant maze of closed courtyards, dark chambers and rising towers. Though there are boardwalks at some sections, it is a raw experience to explore this hidden jewel. This jungle temple makes Ta Prohm, the famous jungle temple at Angkor, look like a groomed little brother.
