There is nothing around the fall. So, it will be nice to combine with your hiking at Mt. Amagi, or when you are traveling with a car, it is very eazy to see for such a beautiful waterfall.
Nikai waterfall (二階滝, nikaidaki) is one of the great waterfalls in Izu. The fall is located on very minor spots. However, there are great hiking course around the fall. If you are traveling around middle of Izu either by car or hiking, try this fall.
