The Capital Region of Maryland consists of the counties near Washington, D.C., which contain sprawling and densely populated suburbs, as well as numerous satellite cities.
The farthest flung and most exurban and rural of the three counties (but still home to a large commuter population), where the main attraction is the main city, Frederick
One of the wealthiest and most diverse counties in the U.S., much of the county is very urban, and home to an enormous commuter population of professionals working in the city and a renowned biotech and medical industry within the county itself
The country's wealthiest majority black county, and is home to the University of Maryland, as well as much of what you would expect to be in D.C.—huge outposts of government agencies like NASA and the Department of Agriculture, as well as the Washington Commanders football team.
The Capital Region is the most densely populated region of the state, home to the most populated Washington, D.C. suburbs, and satellite cities worth visiting, such as Bethesda, Gaithersburg, College Park, Silver Spring, Kensington, and Rockville. Rock Creek National Park is another reason why you would find yourself here—the long bike/running trail is great. Much of it, though, is suburban sprawl that has covered all the once beautiful Piedmont Plateau, and does not constitute any kind of tourist attraction, although plenty visit on business.
Frederick County, while still in the capital's orbit, has a more rural character, as do northern parts of Montgomery County and southern parts of Prince George's County.
Unless you use a private plane, you won't be flying directly into the Capital Region. Commercially, the region is best served by Baltimore-Washington International IATA: BWI, but also by Washington Dulles IATA: IAD and Washington National IATA: DCA.
The main interstates leading into the Capital Region are I-270, which cuts northwest through Montgomery County and continues north to Frederick, I-95, which goes north through Prince George's County to Baltimore, and, of course, the Beltway (I-495), which runs east-west across Montgomery and Prince George's Counties as it circles around Washington, D.C..
From D.C., the main roads leading north into the Maryland Capital Region are (in addition to those listed above) Wisconsin Ave, Connecticut Ave, Georgia Ave—all of which lead into the wealthy and densely populated suburbs of Montgomery County.
Rail and bus service from D.C. is provided by WMATA. Commuter bus and commuter rail service from the Maryland Transit Administration are also available.
A couple of buses from New York also stop in Bethesda.
The Beltway (I-495) and its main arteries (I-270 and I-95) are the best way to travel between the three counties of the Capital Region. I-270 is a very convenient highway for traveling between Montgomery and Frederick Counties, and there's really no better way to go between the two. Unfortunately, there is an odd lack of east-west routes other than the Beltway, which lends to the extreme congestion between Prince George's and Montgomery Counties (and the extreme ire that engenders in the hapless, motionless drivers). The Intercounty Connector (often called the ICC, but signed as Route 200), is a convenient highway that connects Gaithersburg, Aspen Hill, Cloverly, and Beltsville. It is a tolled road, and tolls are collected electronically. Traffic is almost non-existent.
Many drivers unaccustomed to the Beltway find its banked curves with traffic going 65-75 miles per hour, with little to no space between cars, alarming and unpleasant. There are some surface roads that travel east-west, such as Montrose Road/Randolph Road/Cherry Hill Road, East-West Highway (which is actually a street, not a highway), and Route 28 (Darnestown Road/West Montgomery Avenue/First Street/Norbeck Road).
Metro's Red Line serves Montgomery County. The Green Line, Blue Line, and Orange Line serve Prince George's County. Frederick County has no Metro lines. Keep in mind that the Metro system was designed to take people in and out of Washington, D.C., and the lines were built in that direction. Not all areas are close to a Metro station.
The cost to ride the train depends on how far you are traveling and also the time and day of the week. There is a chart at every station to help figure out the cost to ride. Riders pay with a refillable plastic card called a SmarTrip card. Buy a SmarTrip card at any Metro station, at Metro's website, or at some grocery stores.
Riders must tap the SmarTrip card to enter the system, and tap the SmarTrip again to leave the system, and the correct amount is deducted from the amount of money on the SmarTrip card. If a rider needs to leave the system and the rider does not have enough money on the SmarTrip card, there are machines inside the system to add money to the SmarTrip card. It may seem complicated, but other riders are usually happy to help a confused rider. Employees will help but they are not always happy. Eating or drinking is forbidden in the system, but you can carry food or drinks onto the system. There are restrooms at every station, but they are locked. Ask an employee to unlock a restroom if you need to use it. The restrooms are very basic and minimally clean. Some restrooms are broken.
Maryland is building a Purple Line that will connect Bethesda, Chevy Chase, Silver Spring, Takoma Park, College Park, and New Carrollton. It is under construction. It is supposed to open in 2023.
There is also a commuter rail, called the MARC train, that travels into and out of Washington, D.C. It only operates Monday through Friday. It only travels into Washington, D.C. in the morning, and it only travels out of Washington, D.C. in the late afternoon and evening.
Amtrak's Northeast Regional has several trains per day that stop at the New Carrollton Metro station (NCR in the Amtrak system). These trains can be used to get to Baltimore, Philadelphia, or New York.
Buses are a convenient way to travel around the Capital Region of Maryland. Buses run most often Monday through Friday. Most operate on Saturday and Sunday too, but usually less often. Check schedules online or with the Metro cell phone app. Riders can pay using a SmarTrip card or pay with coins.
Uber and Lyft operate in the area. They are a popular and convenient option, especially for traveling to or from areas without access to public transportation. Private taxi companies exist too, such as Barwood Taxi. Tips are optional on Uber and Lyft. Tips are expected on private taxis, usually about ten or fifteen percent of the fare, or a little more if the driver was especially kind or helpful.
In general, the Maryland Capital Region is not the type of place you visit for sightseeing—you visit it to see family, or on business, since it is a huge commercial and residential center. But there are a few odd sights to find off the beaten path. The largest is the Emerald Palace-like National LDS Temple in Kensington, which boasts a spectacular display of Christmas lights and nativity scenes during Advent every year. NASA's visitor center in Greenbelt is another great reason to venture forth from Washington, D.C. for a Maryland attraction. Perhaps the most important sight, though, is Great Falls in Potomac by the C&O Canal on the Potomac River. You'll be surprised by how big and impressive the falls are, and the Maryland side is great for viewing them—you get to walk out along a long bridge to an island in the middle of the river.
The Capital Region sees three main activities outside the capital itself: hiking and biking along the C&O Canal, doing the same in Rock Creek Park, and rooting on the Terrapins at the big University of Maryland sporting events.
Also consider hiking up Sugarloaf Mountain, located in Dickerson. It's a popular local destination for hiking and picnicking. Although the land is privately owned, it is open to the public and no entrance fee is charged.
Bethesda has many top-notch restaurants, serving all the suburbanites who converge upon the small city nightly. For a cheaper and less crowded experience, look for some of the great ethnic restaurants in southern Silver Spring and in College Park. However, by far the region's most authentic and affordable cusine is to be found in the rather unassuming suburb of Wheaton, just north of Silver Spring. Everything from Jewish and Thai, to Japanese and Congolese, can be found in hole—in—the—wall restaurants and strip malls, at very reasonable prices. It would be a shame to visit the D.C. area and miss out on the array of cuisines in this small suburb.
The Route 193 "International Corridor" near Takoma Park has a variety of immigrant-fueled cuisine -- everything from India to Peru. Alas, much of the rest of the region has fallen victim to endless strip malls full of middle-of-the-road chain restaurants.
Serious nightlife aficionados are probably going to want take the Metro into D.C. on the weekends, but someone looking to knock back a drink after work can find reasonable selections in most neighborhoods, especially Bethesda and Silver Spring. College Park is acceptable for these purposes -- but only if you're under 25. Farther out, Frederick has some bars that may be worth your while.
The two neighborhoods with the greatest concentration and range of accommodations options are Bethesda and Silver Spring, as they cater to visitors of D.C., particularly who want to avoid the district's astronomical hotel tax. Many of the residential suburbs of D.C. don't have much by way of hotel options, but there are hotels throughout the sprawl wherever there are clusters of businesses—Rockville, Gaithersburg, Germantown, Laurel, Largo, etc. And of course, farther flung cities and towns like Frederick, Bowie, Greenbelt, etc. all have hotels catering to their own visitors. Camping is available in Greenbelt Park and there is a path to walk from the campground to the College Park Metro stop.
