Dogashima Island, located on the west coast of the Izu Peninsula, is renowned for its exceptional natural beauty, characterized by rugged coastlines, distinctive rock formations, and sea caves. It is a significant geological site, featuring attractions like the Tensado Cave (Skylight Cave), Sanshiro Island, and the Tombolo phenomenon, where a sandbar connects an island to the mainland at low tide. This area offers a unique blend of scenic vistas and geological wonders, making it a popular destination for nature enthusiasts.
Visitors consistently praise the stunning coastal views and the unique experience of the boat tours, particularly the one that passes through Tensado Cave. Many describe the water as crystal clear and the overall scenery as exceptionally fantastic, especially on sunny days. The Nishiizu footpath (Dogashima course) is also highly recommended for its easy walkability and superb views, though some sections involve steep steps. Reviewers often highlight the beauty of the bus ride to Dogashima, with some even spotting Mount Fuji along the way.
For a comprehensive experience, visitors suggest allocating at least 60 minutes for a boat ride, or 120 minutes if you wish to explore the walking paths and perhaps have lunch. It's advisable to bring sun cream, as there are no drugstores nearby to purchase it, and the area can be very hot and sunny. While boat tours are a highlight, some reviewers note that service can be suspended due to strong winds or rough seas, especially in winter. If you have limited time (15-30 minutes), focus on taking photos from the viewpoints. Consider visiting on a clear day to fully appreciate the views and increase the likelihood of boat tour operation.
Dogashima is accessible by bus, with several reviewers mentioning the Tokai Bus. From Shimoda train station, the bus ride takes approximately one hour and costs around 1430 yen. From Shuzenji, the bus journey is about 1.5 hours. The Dogashima bus stop is conveniently located near the pleasure boat dock. Public transport to West Izu is generally less crowded, contributing to a more relaxed travel experience. For those driving, parking is available in front of the Dogashima bus stop.
A common complaint is the frequent suspension of boat services due to weather conditions, particularly strong winds and rough seas. To mitigate this, it's recommended to check the weather forecast before planning your visit and to have alternative activities in mind, such as exploring the walking paths or visiting nearby attractions, in case boat tours are unavailable. Some visitors also found the area less accessible for those with mobility issues due to steep steps on the footpaths.
