I'm a passionate hiker - I don't think this is a surprise for you. But I only discovered my wanderlust when I was over 20. With my parents and siblings I spent most of my holidays by the sea, sun bathing, swimming, reading and doing mostly nothing.
Today I have to admit that I can't spend a whole day lying on the beach anymore. I always have the feeling that I have to move and my boyfriend makes lots of jokes about this fact...
When my family comes to visit me here in Switzerland, I try to get them to go hiking with me from time to time. Yesterday I looked through my archives and I found five easy hikes under 10 km for you, which are good for a family outing. (Not only in Switzerland!)
And in case your family is not too much interested in hiking: Switzerland offers lots of other things to do!
