I love the Finnish lakes. They are peaceful and extensive. We camped right next to two sets of lakes on our way down to Jyvaskyla and then further south. The whole experience was one of tranquility despite the cold temperatures for June.
We thought that it might be busy on the campsites as the children were on their 10 week summer holiday. But, the tradition seems to be that they don’t go away until after Midsummer’s Day and we were leaving the country on that day to head for Sweden. So, quiet campsites and generally quiet everywhere.
