Good advice above. Meiringen is a good centre for the Grimsel Pass, where there are at least half a dozen campsites between Meiringen and the top of the pass. Many more on both sides of the two lakes between here and Interlaken. Bolted climbing at Grimsel and Handegg, Mittagfluh, and lower level sports crags Rotsteinl, Bereitl and others nearby if the higher crags are out due to weather . Swiss Plaisir West is the guidebook. Loads to do on rest days - the Reichenbach Falls, the train up the Eiger to the Monch, swimming, there's even a climbing wall in Meiringen.... blah blah. Just google campsites near Meiringen or Grimsel or Interlaken - sorry can't recommend any personally, but they all looked pretty decent when we passed by.
Hope this helps.
