"Came for the ferry rides to the underground caves. Unfortunately no ships was available. Reason stated was bad weather for the day, though was sunny with very calm seas. Park around the area was quite pretty so all was not lost"

"I took the boat after a heavy rain, therefore it’s not that crowded on the boat, I choose to sit at the outside of the boat, it will be a good choice especially when it is cloudy day! I enjoy soft winds and nice view!
If you like sea views and mountains, you must try this spot!!"

"Must visit spot when in Izu ♥️
Ticket cost ¥1200 for adult and ¥600 for children
The ride took almost 20mins with explanation of each landscape in Japanese.
The ride through the cave where the sunlight above head slides inside is the main attraction and the most spectacular spot.
There is a walking course to the top of one of the caves, but unfortunately there was some work under progress and was closed.
Bus stop is near by and there is also a convenient store."

In-depth insights and expert knowledge
The Geology of Dogashima's Caves
The most striking feature is the emerald hue of the water within the caves. This vibrant color is achieved when sunlight penetrates the water and reflects off the cave's surfaces, creating a magical, almost otherworldly glow. This phenomenon is particularly captivating when the sun is at its peak, illuminating the depths of the caves.
While the boat tour is the primary way to experience these natural wonders, the surrounding coastline also offers breathtaking views. The rugged cliffs and the vast expanse of the Pacific Ocean contribute to the area's dramatic and serene atmosphere, making it a must-visit for nature lovers.
Navigating the Boat Tours
When boarding, consider sitting on the outside of the boat. This vantage point allows you to better appreciate the sea breeze and the expansive coastal scenery, especially on a cloudy day. It also provides clearer views for photography, away from the immediate cluster of passengers.
It's crucial to check the tide and weather conditions before heading out. High tides, even on seemingly calm days, can lead to the cancellation of tours, as access to certain caves might be restricted for safety. Flexibility in your itinerary is key to ensuring you don't miss this unique natural spectacle.
