San'in Kaigan National Park

As the name suggests, the San'in Geopark coastline actually runs from Kyoto prefecutre through Hyogo, Tottori, and Shimane Prefectures. So while the National Park is listed as being located here, its quite extensive, and even includes the Oki islands. The region has wholly unique geological features, rare volcanic rock formations, some of which are jutting right out of the ocean. This would be a spectacular road trip, following the entire coastline, stopping at natural hot springs (again thanks to the volcanic nature of the coast) and local stands that sell local vegetables and fruit (again because the soil is fertile due to previous volcanic activity). I love this coastline and try to explore it whenever possible. It's intricate and there is always something amazing to see.
