This Tour is tide dependant, therefore pickups depend on the tides (Its mostly done during low tides to be able to explore the Robinson Island, a sandbank that pops out during that time) The glass boat has a glass at the bottom and this helps you to have an insight into the amazing world underwater (Different types of fish, interesting marine life and corals) The guide takes you to spots where yo can find interesting marine life in the underwater world. You also get an opportunity to snorkel and swim. The Robinson Island is an amazing little paradise where you can take photos, relax on the sand and sunbathe. This tour happens in Diani and very ideal for people who want a short snorkelling tour and for people with kids.
