Exploring Izu peninsula Geopark Sites

    Ryugu Park and the Heart Shaped Cave

    The Ryugu sea cave is one of the most popular geoparks in Minamiizu. Located near the water, the cave can be ventured inside and out, with a hidden beach inside the cave. Visitors descend down a paved staircase into the inside of the cave. The eroded hole at the top creates a natural skylight that lets sunlight pour down into the tiny bay. The bottom is filled with stones of all shapes and sizes, gently formed by the passing waves. The opening of the cave with the small beach in the foreground has become a popular photo opportunity. Ryugu cave is especially popular with couples. Over time, erosion has formed the top of the cave into a heart shape. The gradual destruction of the rock is similar to romance, the dissolution and decay is seen as beautiful, not tragic.

    Ebisujima Island

    Ebisujima Island is the home of Ebisu Shrine, a ritual site during the Kofun-Nara Period and one of Shimoda City’s cultural assets. When explored beyond its sacred features, visitors to Ebisujima will also be treated to a unique combination of white sandstones and dark rocky cliffs, the result of past underwater volcanic eruptions.
    A concrete path lets visitor walk around this small island and take a closer look at the stone formations which change in style as the trail covers the area. During the summer, the volcanic-themed stroll can be complemented by a snorkeling session as the water that surrounds the island is one of the best spots for enjoying the underwater beauty of Shimoda City.

    Aiai Misaki

    The Minamiizu Geopark Visitors’ Center is conveniently located on Aiai Misaki, or Cape Aiai, a tall cliff where visitors can look down into the vast ocean or fields of seasonal flora. The Visitors’ Center is less of an informational spot and more of a rest stop, serving beverages and light snacks. Be sure to arrive in the evening, as the sunset is known to be the best in Minamiizu.

    Iro Shrine and Irozaki Cape

    Located on the side of Cape Irozaki’s rocky cliffs, Iro Shrine might be one of the most perilous spiritual landmarks in Izu. The ragged cliffs and crashing waves are best seen from a sightseeing boat but hikers are able to take in Iro Shrine’s magic up close. Irozaki is located on the southernmost tip of the peninsula and one of the most identifiable landmarks in all of Izu. Hikers can walk to the edge of the dramatic coastline look into the rough waters. Over time the igneous rock has been fiercely eroded into jagged, dangerous entities, unlike the eroded rocks.
