Kratie is one of the four provinces in northeastern Cambodia, and although it is relatively remote and not heavily touristed, travelling here won't earn you points if your priority is to be a pioneer. There's no large scale tourism, but plenty of backpackers pour through here during the peak season. The town has developed to meet this demand, with very good budget accommodation that is well known in backpacking circles.

Phnom Sombok, (10km north of Kratie on a prominent hill). A rather nifty temple north of town and situated on the only hill anywhere near Kratie. A long set of steps lead to a pavilion, the interior of which is painted with more torture scenes, depictions of what happens to those not virtuous enough to lead a holy and clean lifestyle. Makes a good stop on the way back to or from the dolphins. As a little bonus you might catch a glimpse of the family of monkeys that lives around the temple. Free - but visitors are highly encouraged to leave a small donation toward upkeep of the temples. 

Basket weaver villages, (15 km south of Kratie). There are 3 basket weaver villages near Kratie. The biggest is the Cham village Chheu Teil Ploch with 4,000 villagers. 

Villages of the Mekong. There are very interesting places along the Mekong river. You enjoy your day at the villages along both sides of the Mekong river. You can go by tuk tuk or motorbike. 

Ministry of Culture and Fine Arts, (downtown north Kratie). Here you can sometimes catch a musical performance. Groups sometimes come to perform singing contests here, with both traditional Cambodian instruments and Western. Otherwise, nothing else to really see here. Located by the river by the northern roundabout.
