well, it’s not really “not worth visiting,” but it’s not really “worth visiting” either. it’s just one of those things to do if you can’t really find anything else to do. the island itself is nice, but ferry lines are sometimes unpleasant. it is usually rainy and unbearably cold or there are long lines and it’s unbearably hot. if you find one of those days with the perfect weather for riding the ferry, then it would be a good place to go.
