Tonle Sap sanctuaries, rare waterbirds and guided birding tours
Cambodia is an important birding destination in Southeast Asia, especially for large waterbirds. The seasonally flooded forests and grasslands around Tonle Sap support colonies that have declined elsewhere in the region.
On the northwest edge of Tonle Sap Lake, Prek Toal is the standout site. In the dry season (roughly December–May) it hosts large colonies of storks, pelicans, ibises and cormorants. Access is by boat from floating villages; a local guide and permit are required.
A protected reservoir area in Banteay Meanchey known for the endangered sarus crane and other waterbirds. Best visited in the dry season with a specialised guide.
Protected forests in Preah Vihear, Mondulkiri and Ratanakiri hold forest species for more experienced birders. Access can be remote; arrange through specialists.
Mangroves, salt pans and coastal flats near Kampot and Kep attract shorebirds and mangrove specialists, especially on migration.
Peak birding for large waterbirds is the dry season (December–April), when water levels drop and colonies concentrate. Migratory shorebirds are best in the passage months.
These experiences are offered by local operators across the country. Travellers can compare options online or through hotels.
