We have been to Como, Maggiore, and Garda- loved them all. Garda is the busiest and best for families (especially the town of Garda itself); Como and Maggiore are quieter and more for couples. My favourite place of all 3 Lakes is Bellagio on Como - steep cobbled streets and lovely little shops and restaurants. If you go to Como, you can easily get to Bergamo - a gorgeous medieval town (black and white half-timbered houses, very quaint). The best bit of visiting any of the Lakes is being able to get the Lake ferries and visit all the different resorts, we did this every day, absolutely no time to get bored, there's so much to see. To me, the Italian Lakes are so like our Lake District - breathtaking scenery and views, but with much better weather and much better food!
