Afternoon Hike in Saint Mary’s River State Park: Hidden Gem! Moderate 8 Miles

"Situated at the northern end of the St. Mary's River watershed, the park shows a wide range of habitats, from wooded acres and fields to swamps and small streams. With such a diversity, you can also find many different types of plant and animal species." From the park's home page

Boasting more than 8 miles of pristine trails, St. Mary's Lake is a fantastic destination. Southern Maryland does not usually conjure up images of great hiking destinations. However, near Lexington Park, north of St. Mary's City in St. Mary's County, is a small treasure not too many hikers know about -- St. Mary's River State Park. St. Mary's River State Park is a park that is not well known, but a real treasure. The park is located on the headwaters of the St. Mary's River, and is divided into two sites. This 8-mile trail encircles the 250 acre St. Mary's Lake.

Prior to the landing of England's colonists and as far back as 3,000 years ago, several Indian tribes, including the Piscataway-Conoy, Algonquins, and Susquehanocks, called this area home. Evidence of their existence can still be found along the banks of the river in the form of arrowheads, pottery, and ax heads.

The hike's lack of serious elevation change makes this trail ideal for those new to hiking. A more advanced hiker should not be discouraged, however, due to the great biodiversity.
