If you're going to spend the day in Pailin, Otavao Waterfall is the area's top attraction.
It's an easy trek to the top with several different sets of stairs along the way that lead down to the falls.
An unnamed restaurant is at the top and offers Khmer food and cold drinks. It's a great place to rest as it overlooks the falls and offers marvellous views of the surrounding lush scenery.
Several canopies are dotted along the falls and serve as good spots for resting or a picnic. It's best visited during rainy season, but either way, you'll likely have the site to yourself.
Admission is $2 for foreigners, free for locals. The falls are around 9km south of Pailin town.
