About St. Mary’s

Welcome to St. Mary’s!

This Chesapeake Bay destination is brimming with history, outdoor fun, vibrant culture — and passionate people eager to share it all with you.

Wide-Open Water

Cradled by the Potomac and Patuxent Rivers and the Chesapeake Bay, St. Mary’s is a peninsula with a 500-mile shoreline to explore. Here, you’ll find five water-based state parks, numerous water trails, abundant opportunities to fish, camp and hike — and of course, fabulous seafood to savor.

Eventful History &
Scenic Pleasures

This fertile location destined the area for an eventful history. This is Maryland’s birthplace. The story of Maryland’s early beginnings unfolds at the area’s colonial sites while its maritime heritage comes to life at its four lighthouses and its waterside communities. The rural landscape holds its own pleasures of afternoon drives, scenic cycling, and farm and winery rambles.

Fresh, Local & Fun

Thanks to the presence of the Patuxent River Naval Air Station — the U.S. Navy’s premiere site for military aviation testing — today’s St. Mary’s has a young population with a high-tech ethos and a drive to live healthy, eat well and play hard. Restaurants with an eye for what’s fresh and local, historic towns with a trendy edge, fun weekend events, and even some top-flight motorsports venues keep things interesting.

Absolutely Affordable

You’ll find hundreds of great places to visit and as many warm and engaging people to meet when you do. And, because St. Mary’s is so close, it’s also affordable. St. Mary’s makes a great day trip or weekend getaway without breaking the bank.
