Kratie is famous for the colony of freshwater Irrawaddy dolphins that inhabits the Mekong River some 15 km (9 miles) north of town. The dolphins are most active in the early morning and late afternoon. Taxis and hired cars with driver from Kratie charge about $10 for the journey to the stretch of river where the dolphins can be observed. You will likely have to hire a local boatman to take you to where the dolphins are,
as they move up and down the river.
