Zurich to Lake Como

[snorkel sucker]

Heading from Zurich (airport) to Lake Como next week and the current plan is to go via the Klausen Pass then down to Andermatt and the Gotthard Pass. The other option is the St Bernadino route via Chur, but I think we'll do that on the way back, as its a little further and we have more time then.

Anybody done a similar journey? Have any tips? Alternatives etc?
