Your meeting time is 9.00am or 2.00pm, so don't come before to avoid waiting or too late to miss the departure (30 minutes later). During the boat trip you will be able to discover the magnificent relief of our coasts, often inaccessible by land and our instructors will give you a ten minute briefing to explain how it will happen, what you need to know and what you will have to do underwater. On arrival at the site, you will be able to snorkel and then go underwater (for about 30 minutes) with your instructor to discover the wonders of our underwater world. Discover the fauna and flora, the richness of our Mediterranean Sea as well as the remarkable underwater geology: The end of the Alps which flow into the sea! After these 3 hours spent at sea we will be back around 12-12:30 or 17-17:00... A snack will be served on the way back from the boat to better appreciate our coasts and its magnificent beaches ;-) Note : For children under 18 not accompanied by their parent(s) a parental authorisation will be required.
