Prince William Forest Park is an oasis, a respite of quiet and calm. In 1936, Chopawamsic Recreation Area opened its gates to house children's 'relief' camps during the Great Depression. Renamed Prince William Forest Park in 1948, these fragrant woods and trickling streams have welcomed generations of campers, hikers, bikers and nature lovers.

The combination of 10 hour fuel moistures around 10 to 12 percent
relative humidities around 20 to 25 percent, and frequent wind
gusts around 20 to 25 mph will lead to an increased risk for the
rapid spread of wildfires today. Even with some light rainfall
yesterday, there was adequate sun and gusty winds this afternoon
to rapidly dry fuels.
Residents and visitors are urged to properly dispose of cigarette
butts, matches, and any other flammable items in appropriate
containers. Additionally, exercise caution if operating any
equipment that could create sparks and keep vehicles off of dry
grass. Most dry grasses, dead leaves, and other tree litter could
easily ignite and spread fire quickly.
Lastly, remember to obey local burn bans. For more information about
wildfire danger, burn restrictions, and wildfire prevention and
education, please visit your state forestry or environmental
protection website.
