Take a high-speed boat tour of the Otaru Blue Cave. The boat is covered, so you won't get wet even in light rain or waves. There are ample seats for those concerned about sunburn, and there are bench seats so you can sit next to your children. Enjoy the unique experiences of speed, thrills, and excitement, while visiting the Otaru Aquarium, a famous rock climbing spot, the remains of a Showa-era amusement park, and a 100-meter cliff before arriving at the entrance to the Blue Cave. Perfect for taking photos of the cave and Mado-iwa Rock! The Prolomarine boat is also the only one that allows you to move around the boat, allowing you to capture photos from the angle you want. The blue color of the water in front of the cave changes depending on the weather and season. On clear, calm days, you can even see wild sea urchins up close next to the cave. This exciting activity cruise, with its spectacular views only available from the ocean side, is a hugely popular tourist spot in Otaru. Don't miss this opportunity! The reliable cruise and feeding of seagulls are popular. On July 17th at around 2pm, a part of the upper part of the entrance to the Blue Cave collapsed. Until it is confirmed to be safe, we will not be entering the cave and have changed the itinerary so that you can view the cave from the outside.
There are few cruise tours in Hokkaido. There are various things to see such as the fantastic blue cave, the cliffs, the ruins of a hidden amusement park in the Showa period, the Otaru Aquarium, and the banya that flourished at the time of herring fishing! You can take a lot of good pictures. In addition, you can enjoy a sense of speed up to the cave! !!
The amount of sunlight is easy to stabilize, and the blue cave is often seen unexpectedly beautifully not only in fine weather but also in cloudy weather and rain. Also, since the area around the cave is surrounded by cliffs, direct sunlight does not reach it, so there is little extra light and the blue is easy to see! !! In addition, there are many departure flights due to the daylight hours, so you can choose a time zone that is convenient for you. On rare occasions, you may encounter wild dolphins and whales that you do not usually see.
The prolomarin ship has been devised so that customers can enjoy it. The seat in front is the most attractive with a feeling of liberation and attraction elements! !! If there are many applicants, we will take turns on the way back and forth. The seats are not fixed, so you can move on the way. In addition, the prolomarine ship is also excellent in dealing with waves and draining performance, and it is full of speed, thrill and power! !! There is no doubt that it will be exciting! !!
