I found some great tips on old threads here on things to do in Samoens in summer, thanks.
Can anyone recommend shortish (3-4 miles max?) walks high in the mountains round about? Maybe going up and down the mountain in a gondola/chair lift thingummy, to maximise the fun bit (and minimise the whinging from DS2 (7) who Does Not Like Walks). I've had a poke around various Samoens and Grand Massif websites, but not yet found anything.
