Prek Toal is one of three biospheres on the Tonlé Sap lake, and this stunning bird sanctuary makes it the most worthwhile and straightforward of the three to visit. It is an ornithologist’s fantasy, with a significant number of rare breeds gathered in one small area, including the huge lesser and greater adjutant storks, the milky stork and the spot-billed pelican. Even the uninitiated will be impressed, as these birds have a huge wingspan and build enormous nests.
Visitors during the dry season (December to April) will find the concentration of birds like something out of a Hitchcock film. It is also possible to visit from September, but the numbers may be lower. As water starts to dry up elsewhere, the birds congregate here. Serious twitchers know that the best time to see birds is early morning or late afternoon and this means an early start or an overnight at Prek Toal’s environment office, where there are basic single beds for US$15 (doubles US$20).
Several ecotourism companies arrange trips out to Prek Toal including the Sam Veasna Center , in the Wat Bo area of Siem Reap, and Osmose . Tours include transport, entrance fees, guides, breakfast, lunch and water. Binoculars are available on request, plus the Sam Veasna Center has spotting scopes. Both outfits can arrange overnight trips for serious enthusiasts. Some proceeds from the tours go towards educating children and villagers about the importance of the birds and the unique flooded-forest environment, and the trip includes a visit to one of the local communities. Day trips include a hotel pick-up around 6am and a return by nightfall.
Getting to the sanctuary under your own steam requires you to take a 20-minute moto (US$3 or so) or taxi (US$15 one way) ride to the floating village of Chong Kneas (depending on the time of day additional fees may have to be paid at the new port), and then a boat to the environment office (around US$55 return, one hour each way). From here, a small boat (US$30 including a guide) will take you into the sanctuary, which is about one hour beyond.
Sunscreen and head protection are essential, as it can get very hot in the dry season. The guides are equipped with booklets with the bird names in English, but they speak little English themselves, hence the advantage of travelling with the Sam Veasna Center or Osmose (both of which provide English-speaking guides).
