Hotel
There are many great Airbnb's and Bed & Breakfasts in and around downtown Frederick!! If you are interested in staying at a hotel, we recommend The Hampton Inn and Suites Frederick-Fort Detrick.
Flight
BWI is usually the easiest airport to fly into since you avoid the major DC traffic! It's also the closest to Frederick (about 45 minutes). However, if your transportation plans would be smoother flying into Ronald Reagan Washington National Airport (DCA) or Dulles International Airport (IAD), those are both a little further, but great options as well.
