edymonster, I wouldn't rule out the C172; if you're going in Summer the odds are you'll be going during more favourable wx anyway than now. (Snow covered mountains camouflage quite nicely in IMC
) Flying around Geneva and to be honest from Zurich to Geneva is pretty straight forward. Running up to Sion (Verbier) from Bern, Grenchen or Geneva are all do-able. The valleys are huge and you'll certainly enjoy the views + get up close to the rock. You might even want to route southwards of LSGG running along the valley with the B41 road towards Sallanches Mt-Blanc (LFHZ) and the white mountain itself.
All the best,
