Aland has another distinction: It has an interesting trade status which allows ships which port there to run duty-free shops.
A popular cruise is a day trip from Stockholm to Aland. A lot of people don't even get off the ferry. There are three draws: the scenery, the smorgasbord, and the duty free shop. It is quite inexpensive and most people spend more in the duty free than they do for their ticket.
My wife and I took this day trip last summer and I would recommend it.
Which line runs it? Is it one of the Vaxholm Ferries or one of the major cruise lines? (Cinderella, Viking, Tallink, etc????)
We took the 1000 Islands tour last summer through the Archipeligo stopping in Sandhamn... what a gorgeous area. Hopefully this summer, we'll make an overnight cruise on Tallink to see Tallinn.
