Have you thought about Alaska? That time period is at the tail end of the tourist season. There’s plenty for outdoorsy/hiking for you and your mom and bf could enjoy the sights more – tons of cruise ships port there, so I imagine something that fits their needs is available.darkmatterhunter
I would do Washington-Philadelphia-New York-Boston by train given your interest in cities, food, sporting events, and other performances. The only thing that route doesn’t really give you on your list are natural attractions.lh123456789
Maybe add Acadia National Park for your nature fix. It’s one of the few parks where you’d be able to do a lot without a car (Island Explorer Shuttle connects popular sites).
Don’t feel like you have to go to NYC. You can catch touring companies of Broadway shows in pretty much every mid- to large city in the country.
Based on how dry things are now, reports are suggesting it’s going to be a terrible fire season out west. Just another thing to consider.mediocre_publisher
I would suggest the Pacific Northwest. Around Seattle and Portland. You get a taste of what our cities entail while also having the ocean and mountains surrounding you.
Honestly, I just spent 2.5 weeks in Spain and I can’t fathom why anyone from Europe would want to see any of our cities. They’re lifeless dumpsters with no architecture or history; once you’ve seen one you’ve seen them all.
Honestly, visit our National Parks and if you must see a city pick one near a park.Awanderingleaf

What is My Favorite Place in the US to Visit in Fall
One of my best fall vacations has to be visiting the Smoky Mountains in Tennessee – it was like stepping into a postcard! I do not have enough words to explain the fiery autumn hues of the forest; they were simply out of this world.
The area was quiet and serene, which was exactly what I was looking for – to escape the bustle and hustle of New York City. Every twist and turn of the hiking trails (and we did many!) was met with something new to see and the smell of pine has become my new favorite scent!
The Alum Cave Trail was superb as we walked over crunchy golden leaves to reach the narrow Arch Rock tunnel. I’m almost certain we heard black bears in the distance, but I’m rather glad we didn’t see any! At night, my partner and I cozied up by the campfire, stargazed, and sang old ’60s blues at the top of our lungs.
What I can say? The Smoky Mountains have stolen a piece of my heart and I’m sure it would do the same for you! (Just book your accommodation in advance, okay?)
So there you have it! A complete rundown of the best fall vacations and things to do in the US during September.
