We’re heading on a family holiday to Lake Como in August and have a week booked at a lovely place that we’ve stopped at before. However we’d like to extend the stay for a few days and are looking for recommendations of nice villages/towns within a reasonable distance (so we don’t lose too much time travelling) - any suggestions? I have considered just moving to another resort on the lake, or possibly going to Lake Maggiore (the Swiss end?) or elsewhere into Switzerland but not really sure where. Ideally somewhere really pretty 
A friend suggested Lauterbrunnen but I’m wondering if that’s too far for 3 days or possibly a difficult journey through the mountains?
We’re travelling with my parents (reasonably fit) and children aged between 9 and 17 who are all fairly outdoorsy and don’t require huge amounts of entertainment.
Also, although we’ve been to Lake Como before, this is the first time we’ve travelled from the UK - can anyone help with the most convenient Milan airport to fly into to transfer to Como? Our local UK airport is probably Bristol but I don’t mind flying from somewhere else (Gatwick, Birmingham etc) if it’s easier, as long as it’s not too far away (eg Stansted!)
Thanks I’m advance
