The Blue Safari or island tour is typical for Zanzibar. It is dhow sailing combined with many diving stops. The point is not to see the islands, but as much of the underwater world as possible.
As on a land safari, it is also our goal at the blue safari to enjoy the wide landscape, to visit different hotspot of the herds, to observe robbers and special animals of the savannah/on and in the water.
This includes snorkeling in coral reefs, possibly a swim with dolphins, depending on the season you can see whales and definitely visit the mangrove.
