Hi, I am planning on a 3 week visit to europe, going solo, in October (right after Succos). I am not a fan of detailed itineraries, but I do need to choose a rough plan of where I'd live to visit, if not the exact dates. I'll be booking an open-jaw flight and want to start off in London, followed by Paris. After that, I am looking for suggestions on cities/countries to visit.
I love scenery and outdoors. I'd like to get a mix of historic sights and more scenic visits. I was considering following Paris with Amsterdam, Switzerland, Venice and Rome and returning home from Rome. I am open to any suggestions on improving my itinerary.
I know this is a very vague request, but I would love to hear your suggestions.
