Either take a flydrive holiday or a leisurely sail drive package via Rotterdam.
Sweden has lots of forested hills, peace, tranquillity and wildlife. Summers in Sweden are generally warm and sunny, particularly in central Sweden near the pleasant town of Saffle.
We have two delightful self catering cottages for rent and a perfect time to visit is September when the colours of trees change from green to gold and red. A variety of wildlife can be seen too, moose in particular are quite common.
