Yes

Yes go on website

Yes there are from the visitor's center to downtown

Or you can park using parkmobile app right by the station and pay for the parking. 😊 This is how I do.

You have to pay $15.00 to park and preferably take the blue bus into Harper's Ferry because where you get into the historic area there is minimal parking, look for Park entrance. Off of route 340 also known as the William Wilson Parkway.

It's less than 30 minutes drive to historical sites like Antietam Battlefield and natural wonders like the Crystal Grottoes stalactite cave. Not to mention hiking and River rafting/ tubing.

Only leashed dogs.

I'm not sure the shuttles are running. There is a website that shows what holidays they partake in.

No, just a cargo line that runs through it
