The walk was more of a stroll, really, down the valley back to the bottom of the funicular railway, with a combination of spectacular mountain views, and paths through the cool forest beside streams. There was a section along the way with a series of wooden adventure playground constructions - an enormous see-saw, a balance beam, and a set of forts. It is hard to imagine a better walk.
After a sustaining lunch in Murren, with far too much cheese consumed all round, we found some more public transport to a place called Pfinstegg - a cable car ride from Grindelwald (which appears to be the tourist trap town of this part of the Alps).
Up there, we had an exhilerating afternoon on the summer toboggan - Declan and Callum both had a go with every available adult, and Declan declared after about five goes that he was now addicted - "there must be a special chemical in the toboggan which makes me addicted to it". The advertising says you can go at up to 40km an hour, and it certainly felt it.
This day felt like a perfect Alpine day.
