About this park

Darnalls Chance Historic Site

Darnall's Chance Historic Site is located in Upper Marlboro, Maryland. The site is a historic farmhouse that was built in 1742. The farmhouse was once home to the Darnall family, who were prominent residents of Prince George's County.

There are several reasons to visit Darnall's Chance Historic Site. Firstly, the site offers visitors a glimpse into the life of the Darnall family during the 18th century. Visitors can explore the farmhouse and learn about the family's daily life and customs.

One of the main points of interest at the site is the historic gardens. The gardens have been restored to their 18th-century design and feature a variety of flowers and herbs that would have been common during that time.

Another interesting feature of the site is the slave quarters. The quarters provide insight into the lives of enslaved people who lived and worked on the farm.

Interesting facts about the site include that it was used as a hospital during the Revolutionary War and that it was once a stop on the Underground Railroad.

The best time of year to visit Darnall's Chance Historic Site is during the fall when the gardens are in full bloom and the weather is cooler. However, the site is open year-round and offers guided tours and educational programs for visitors of all ages.

Park & land designation reference

A quick legend for the federal and state land categories Snoflo tracks. Each designation comes with different rules around access, recreation, and resource extraction.

National Park
Large protected natural areas managed by the federal government to preserve significant landscapes, ecosystems, and cultural resources; recreation is allowed but conservation is the priority.
State Park
Public natural or recreational areas managed by a state government, typically smaller than national parks and focused on regional natural features, recreation, and education.
Local Park
Community-level parks managed by cities or counties, emphasizing recreation, playgrounds, sports, and green space close to populated areas.
Wilderness Area
The highest level of land protection in the U.S.; designated areas where nature is left essentially untouched, with no roads, structures, or motorized motorized access permitted.
National Recreation Area
Areas set aside primarily for outdoor recreation (boating, hiking, fishing, often around reservoirs, rivers, or scenic landscapes); may allow more development.
National Conservation Area (BLM)
BLM-managed areas with special ecological, cultural, or scientific value; more protection than typical BLM land but less strict than Wilderness Areas.
State Forest
State-managed forests focused on habitat, watershed, recreation, and sustainable timber harvest.
Bureau of Land Management (BLM) Land
Vast federal lands managed for mixed use -- recreation, grazing, mining, conservation -- with fewer restrictions than national parks or forests.
