Get back to the nature and laid back environment
Most of traveller to Cambodia think about the temples of Angkor. Well, nothing wrong with that as Angkor is one of the world's seven wonders.
However, Cambodia has more to offer - not just many historic stone temples.
The northeastern part of Cambodia, particularly Ratanakiri province, is home of a genuine ecotourism in Cambodia. Life pace here in Ban Lung (the Ratanakiri provincial capital) moves much slower than the rushed town of Siem Reap which is the base for exploring the temples. In fact, the province is just starting to be visited by a handful of tourists.
The crystally clear water of the Yaklom volcanic lake, many waterfalls, the contry's largest national park (Virachey), and many groups of indigenous ethnic minority people are some of the main attractions in Ratanakiri. There are also many ecotourism activities, such as trekking, village homestay, elephant ride, and so on that await the green travellers.
A good source of information of the province may be found in one ecolodge's website : www.yaklom.com The website seems to provide the last minute travel information about Ratanakiri and tips during travel.
