Things to Remember  

  • Help to keep your parks beautiful -- please take your trash and recyclable items home. Take only pictures and leave only footprints. 
  • Dog droppings may attract disease-harboring pests, and even a friendly dog can scare the birds, wildlife and park visitors. Clean up after your dog and keep it leashed; it's the law. 
  • All of our parks are inhabited by a wide variety of wildlife such as deer, snakes, fish, rabbits, insects and birds. Please do not disturb them; remember, this is their home.

Howard County Bans Smoking in All County Parks

In a continued effort to be a model public health community and preserve its rank as Maryland’s Healthiest County, Howard County was the first jurisdiction in Maryland with a total ban on smoking and tobacco products of any kind in all the 57 County-owned parks and recreational areas. Enforcement will take the form of requesting voluntary compliance. However, if a smoker does not extinguish a smoking product, park staff will remind them of the new policy and could request exiting the property if they choose to continue smoking.

Pavilion Rentals

Pavilion Rentals

Park pavilions are a great place to hold a birthday party, corporate event, large family gathering, school picnic or any other special occasion. Pavilions vary in size to accommodate any group, and many come equipped with cooking facilities.


The pavilion rental season runs from April 1 through Nov. 30, rain or shine (there are no refunds for inclement weather).


Pavilions are available free on a first-come, first-served basis during the remainder of the year. However, restroom water and water fountains are turned off during winter months and grills may not be available or accessible during this time due to winter maintenance. Your rental may begin as early as 10 AM and must conclude by sunset (times subject to change).  

You MUST leave the park by the designated time of sunset or be charged a late fee of $25 per ½ hour.
