There aren't many places to stay in Boseong, since it is mainly an agricultural area. However, if you want to overnight in the region, you can stay at any number of minbak or yeogwan in the seaside town of Yulpo. Most places are similar and usually cost W25,000 to W30,000, but be forewarned that prices can double during the popular summer season.
For a unique experience, you and your family can stay overnight at the Ungchi Vacation Farm, 1412-4 Gangsan-li, Ungchi-myeon, Boseong-gun, Jeollanam-do (tel. 063/852-6300), a sort-of government-run farm, located in the middle of a dense pine forest. They have a huge mushroom field, freshwater shrimp, chickens, and a deer "farm" within an enclosed forest.
