Ill aux Cerfs is over rated - If you love being on the water then you'll love this. Crew made us very welcome and lunch was tasty and there was plenty of it. Not a vast choice of drinks but enough to satisfy most. Waterfall is worth a look but we didn't rate the Ile aux Cerfs which is basically a barren island with a lot of coral on the beach and very shallow bathing. Beach shoes are essential. Only one bar and restaurant so thay can charge what they like as you are a captive audience. Oh, and we never did find the toilets! Our driver was late picking us up - he went to the wrong hotel - so we were worried that we might miss the boat, so we asked him to ring ahead to let them know we were coming. Our journey there was at speed but was more leisurely on the way back, so much so we fell asleep in the car! We give the driver a 5 euro tip which we though was reasonable bearing in mind he was late, and he looked less than impressed so wont give anything next time or will use a different transfer company.
