Mt. Monomi 375m tall
The hiking trail of Mt. Hiwada and Mt. Monomi is great hiking for a family with small kids because it is very easy and there is no hard steep pass on this trail. From the parking to the top of Mt. Hiwada takes about 1 hour, and to Mt. Monomi takes another 1 hour. So, the entire trail takes about 4 hours of hiking. There are many restrooms on the trail.
