We are travelling to Germany in early April, flying in from London. There will be 5 of us, plus maybe picking up a 6th in Germany. We plan on flying to Stuttgart around 4/8/19 (Sunday) and flying back to London either Thursday 4/12 or Friday 4/13, depending on what we schedule to do.
We are thinking about staying in Herrenberg and exploring the Black Forest region for a day or two. My daughter's partner was raised in the area, so she wants to show us around. I'd most likely rent a van or something for all of us.
We then have a couple of days for Something Else. Not sure just what that Something Else will be. We have thought of taking a train to Salzburg and spend a day or two there. Alternately, a suggestion was made to visit Switzerland, but I am not sure how practical that would be, or where to visit.
We tend to like castles, cathedrals, quaint villages, beautiful scenery, etc. Ages of travelers range from the mid-30's to mid-60's to mid 70's (though the 77 year old is in great shape and walks every day).
Any suggestions?
