Overview
Lexington Park is a small unincorporated community in St. Mary's County, Maryland, situated on a peninsula flanked by the Patuxent River and its tributaries near where they meet the Chesapeake Bay. With a population of roughly 11,600, it functions primarily as a service hub for Naval Air Station Patuxent River (NAS Pax River), one of the most important naval aviation testing and evaluation facilities in the United States.
The town grew substantially during and after World War II in direct response to the establishment of the naval station, and that military heritage remains the dominant thread in local life today. Defense contractors, government workers, and military families make up a significant share of the community. Visitors tend to be here for a specific reason — aviation enthusiasts, relatives of service members, or travelers passing through Southern Maryland's largely rural landscape.
Despite its modest size, Lexington Park offers genuine points of interest: a respected aviation museum, quiet waterfront parks, fresh seafood, and easy proximity to historic St. Mary's City and other Chesapeake destinations. It is not a conventional tourist town, which can be part of its appeal for travelers looking for an authentic slice of Maryland's Southern Shore.
Before You Go
Visas and Entry
Lexington Park is in the United States. For entry requirements, visa rules, and ESTA eligibility, check TravelerPulse's Visas section and consult the official U.S. Customs and Border Protection website or your nearest U.S. embassy or consulate.
Access to NAS Patuxent River
The naval air station itself is a secure military installation. Members of the public cannot freely enter the base. If you plan to visit the Patuxent River Naval Air Museum, note that it is located at the main gate area and access procedures may apply — verify current visitor policies directly with the museum before your trip, as security requirements can change.
What to Pack
- Warm layers are advisable even in summer, as evenings near the water can be cool.
- Insect repellent is useful in warmer months, especially near tidal wetlands.
- Sunscreen and waterproof gear if you plan any boating or waterfront activity.
Connectivity and Services
Lexington Park has standard US mobile coverage from major carriers. Banking, pharmacies, grocery stores, and gas stations are readily available along Great Mills Road and nearby commercial corridors.
Getting There
By Air
The nearest major airport is Ronald Reagan Washington National Airport (DCA), approximately 70–75 miles north. Baltimore/Washington International Thurgood Marshall Airport (BWI) is a comparable distance. Both airports offer rental car facilities, which is the most practical option for reaching Lexington Park, as no direct public transit connects them to the area.
By Car
Lexington Park is most conveniently reached by car. From Washington, D.C., the primary route is south on MD-5 (Branch Avenue) through Prince George's County and into St. Mary's County. The drive typically takes 1.5 to 2 hours depending on traffic, with congestion on MD-5 during peak commuting hours being a common issue. From points north via I-495, travelers generally take MD-5 south or US-301 south to MD-234 west.
By Bus
St. Mary's County has a local transit system (STS — St. Mary's Transit System) with routes serving Lexington Park. Intercity bus service is limited; verify current schedules and routes at the county's official transit page or locally, as schedules change seasonally.
Getting Around
Lexington Park is a car-dependent community, and having a personal vehicle or rental car is strongly recommended. The commercial and residential areas are spread along arterial roads, with limited pedestrian infrastructure connecting major points of interest.
Local STS bus routes serve some corridors within the community and connect to other parts of St. Mary's County. Rideshare apps (Uber and Lyft) are available but coverage and wait times may vary, especially outside peak hours. Confirm availability before relying on them for time-sensitive trips.
For those with access to or renting a boat, the Patuxent River offers a scenic and practical waterway connection to other Southern Maryland communities and the broader Chesapeake Bay.
Things to See & Do
Patuxent River Naval Air Museum
This is the primary visitor attraction in Lexington Park and one of the standout aviation museums on the East Coast. The museum documents the history of naval aviation test and evaluation, with a collection of historic aircraft, interactive exhibits, and archives related to NAS Patuxent River. It is free to enter, though visitor access procedures at the installation's gate should be verified in advance. Check the museum's official site for current hours and any access requirements before visiting.
Waterfront Parks and the Patuxent River
St. Mary's County maintains several waterfront parks accessible from the Lexington Park area. These offer fishing, picnicking, and quiet spots to observe the tidal Patuxent River and its wildlife. The area's wetlands and shorelines support herons, osprey, bald eagles, and migratory waterfowl, making it appealing for birdwatchers.
Proximity to Historic St. Mary's City
Roughly 10 miles south of Lexington Park lies Historic St. Mary's City, Maryland's first colonial capital (founded 1634) and an outdoor living history museum. It is one of the most significant archaeological and heritage sites in the Mid-Atlantic region and a worthwhile half-day excursion from Lexington Park.
Seasonal Outdoor Activities
- Fishing for striped bass (rockfish), blue catfish, and perch in the Patuxent River
- Recreational boating and kayaking on tidal waterways
- Crabbing in summer, a deeply ingrained tradition in Southern Maryland culture
- Cycling along quieter county roads through farmland and forest
Food & Drink
Southern Maryland has a distinct regional food identity rooted in Chesapeake Bay seafood traditions. Expect blue crabs (steamed with Old Bay seasoning), crab cakes, oysters, rockfish, and softshell crabs to feature prominently on local menus during appropriate seasons. The quality and freshness of seafood here is generally high given the proximity to commercial fishing operations on the Patuxent and the Bay.
Lexington Park's dining scene is largely composed of casual sit-down restaurants, seafood shacks, chain establishments serving the military and contractor community, and a scattering of independently owned spots. The restaurant landscape along Great Mills Road and nearby commercial strips tends toward the practical rather than the destination-dining end of the spectrum.
For the most memorable meals, look for smaller local seafood restaurants or crab houses, particularly those open during summer crab season. Visitors should be aware that some seasonal establishments adjust their hours or close in the off-season — it is worth calling ahead. Locally brewed beer and Southern Maryland wines from nearby vineyards are available in some restaurants and at retail outlets.

Safety
Lexington Park is a generally safe community. Like many areas with significant transient and contractor populations, it has some neighborhoods with higher property crime rates; exercise ordinary urban precautions with valuables in vehicles and in unfamiliar areas after dark.
The area around the naval station is monitored and generally orderly. Do not attempt to photograph secured areas of NAS Patuxent River or approach restricted entrances — U.S. military installations enforce security regulations strictly.
Traffic on MD-5 and Great Mills Road during morning and afternoon commuting hours can be heavy and occasionally chaotic; drive attentively. During summer, boaters on the Patuxent should be aware of military exercise zones and restricted waterway areas that are periodically enforced around the base.
