Rock climbing for a couple of hours with my brother at Gåseborg, on the north-western side of Stockholm.. Warm and sunny like a proper summer day, and the mosquitos were plentiful and hungry.. There are loads of sport climbing routes here, more than 60, but we settled with a couple of fairly easy ones where I lead and Jon followed.. Nice location at lake Mälaren with splendid scenic views from the top of the cliffs where we had lunch..
