I would like to do some snorkelling around shore reefs while on Maggie Is. Which are the best bays that have snorkelling gear to hire? What is the best way to get there from Nelly Bay? I dont plan to hire a car. I think there is a bus that that travels around the island all day picking and dropping off as required but am not sure is this is correct! Or perhaps I could walk there from Nelly Bay? Would really appreciate some advice on this....
