Leisurely stroll along the riverside promenade
About this spot
The riverbed of the Usui River (碓氷川) that flows right next to Isobe Onsen Town. By exploring this riverside during the day where fireworks will be launched at night, you can get a sense of the venue atmosphere. The promenade is well-maintained, and it's a wonderful spot where families can walk slowly while listening to the gentle sound of the flowing river.
