Pack a picnic and enjoy a fun family day out at Yabasekihan Island Park. There's loads of space for the kids to run about and get some exercise.
This outdoor recreational space in Kusatsu is popular with fellow travelers, so make sure it features on your schedule. Don't think that's all there is to do here, though. There are a lot more spots waiting for you to check out after Yabasekihan Island Park. Mount Hiei, Enryakuji Temple, and Ogoto Onsen are nearby.
