Lake Como at a pace that leaves room to actually enjoy it. You board the fastest train from Milan early, before the crowd — seats for the whole group, no standing, no chaos.
Same trick on the way back: we board where the train is still empty, so by the time it fills up at Varenna, you're already seated.
Then a boat across the lake with a top-rated guide who knows when to talk and when to step back. Stops in Varenna, Bellagio, and the Bellano Gorge — a canyon no other tour includes, with suspended walkways above a waterfall you feel in your chest before you see it. For most travelers, it's the highlight of the day.
