A famous hot spring resort in Gunma prefecture is Ikaho. It is located on the east slope of Mount Haruna, known for its good driving roads. Ikaho is characterised by a stone stairs going through the city center. A ropeway from the city center can bring you a little further up the mountain to enjoy a scenic view. It is also the access to an ice skate ring which can be used in the winter season. Instead of using the ropeway, a regular hike also gets you up or down the mountain. Back in the city center, you can enjoy a large variety of sweets shops or relax in one of the many hot springs.
