About the Cities
Starting in Poolesville, MD
Full guide →Rural Montgomery County, Maryland, is a fairly oddball choice for a trip, as people generally don't think to visit the countryside so close to the metropolis just southeast. It gets a fair amount of visitor traffic nonetheless, simply because it is so easy for residents of the close-in Montgomery County D.C. suburbs to get to. In particular, Sugarloaf Mountain is a very popular destination. But if you look a bit further and feel like wandering along quiet country roads, there are other gems to explore, be they farms where you can go picking, petting zoos, wineries, or even Maryland fried chicken.
