Yesterday my friend Stellan showed me that it's possible to go on a day trip abroad for all of 60 SEK. To be more precise, we went to Åland with M/S Eckerö. The ridiculously low price, including bus travel Stockholm ↔ Grisslehamn, is clearly intended to be compensated by you buying lots of taxfree booze. They made a loss on us.
On Eckerö you end up basically in the middle of nowhere, which was just what we needed—we walked down the coast, found a nice rock cleft and then sat there the rest of the day watching the waves and a flock of eiders catching fish. (Well, I took the opportunity to send off a few messages around the world, but mostly I did nothing too.)
Still, a bit strange to travel several hundred kilometres just for the pleasure to do nothing.
