There is a secret cave on Kouri Island that can only be visited under natural conditions such as wind and other weather conditions, wave height, low tide, and high tide! There are a lot of things that we can't usually go on a tour, and in places that we are lucky enough to be able to go, there are still unknown heart-shaped fantastic landscapes. *We will move to the cave by marine activities (banana boat, marble, jet) This is the recommended plan of COCONUTS CLUB that we would like to introduce to everyone! ① Preparation, filling out the consent form, explanation of the tour contents (about 15 minutes) ⇩ ② Experience We will land on the secret cave from the sea and tour. (About 40 minutes) ⇩ ③ Dissolution * The above flow is a guideline. The flow may change depending on the situation on the day. We check the weather and wave conditions in advance and make a plan reservation, but please note that we may not be able to go to the secret cave depending on sudden bad weather or rough waves.
A secret cave that can only be reached if all conditions are met, depending on the height of the waves and the weather such as low tide and high tide.
If you are lucky enough to be able to go there, there is a heart-shaped landscape that is not yet known. Let's find a new heart! !
It is still unknown because it is a place that can only be reached from the sea. Show off to your friends.

Selling points regarding safety
Every morning after the morning meeting, all the staff check the sea conditions, and write down the weather, wind direction, wind speed, low tide time, and high tide time on notebooks and whiteboards and let each staff know. In addition, participate in advanced lifesaving at local fire departments, and acquire a BSAC snorkel instructor who can participate after acquiring advanced lifesaving qualifications. Participated in a seminar held by OMSB every year around November. Before the season begins and at the end of the season, we have time for general meetings to review trends and measures for safety.
