Woke to find it had been a very frosty night and fingers crossed, the Motorhome plumbing had not frozen. Set off on a long walk into the Swiss National Park. A lovely walk alongside or above the river through pine forests. Ended up walking 14 miles and ascending over 400 metres to just over 2000m in elevation. Had hoped to see Ibex and Deer but ended up with just a red squirrel and the sound of a woodpecker. Returned to the campsite and lit a bonfire on the beach of the river and drank beer and vodka whilst we warmed by the fire – perfect.
