This trip is just wonderful. The seven islands, which are not really seven by the way, are visited with a big boat, but very closely. They make use of the tide to then wonder around the granite coast and show it's peculiarities. The commentary is excellent and the birds are numerous and beautiful. I went with a fairly bad weather, it had stopped raining but was far from being sunny - the animals do not care anyways, so go also of the weather is not amazing, unless you can just postpone it.
