Byeol Beach Water Park in Gapyeong is a small water park used together with a pension. It has a wave pool, a slide, and a two-person tube slide, and pension guests can use the water park for free. The wave pool and slide operate by time slot, and guests staying overnight can use them on both the arrival day and the departure day. Because the pool is small, children in the fifth and sixth grades finish playing in about two hours.
