The best way to spend a weekend

I used to think that the best way to spend a weekend was to recover from the past week and prepare for the week ahead. A bit of shopping, a film or drinks out maybe, nothing too stressful, nothing too strenuous, nothing too interesting... Actually, I've discovered over the past few months, or maybe even the past year or so, that the best way to spend a weekend is to leave the place you live, do something active you don't usually do, in surroundings that are preferably beautiful and peaceful, and come back refreshed and ready for anything despite the lack of sleep and unusually large quantities of beer that have been drunk in the process...
This weekend we went to Mazuria, the Polish lake district and it was beauuuuuutiful. We went last year too, my first proper trip to Poland, and the weather was as stunning then as it was for us this time - the beginning of September but hot sunny days, clear skies and no hint of Autumn around the corner.
There were four of us and we spent our time kayaking down a river crammed with wildlife, swimming in a beautiful clear blue lake, and on a boat trip (admittedly with a lot of old Bavarian tourists, but the scenery more than made up for that :-)). The food was all fresh fish and traditional soups, the beer was cold and the company great fun. (Who needs intensive Polish courses when you can go away with three Poles?)
So where shall we go next weekend?
