Find more information here on our website, and the latest schedule on the Calendar. See below for the latest news.



In November 2014, the Park Service began the process of redesigning the trails in Patapsco Valley State Park. Trail Manager Dan Hudson led the effort, conducting meetings with different trail users and interested stakeholders, including Sierra Club. 


Please visit the Open House and share your vision for the Park's trail system. Help us create a network of sustainable paths that encourage appreciation of nature with a minimal impact on the environment. 


The Superintendent of the Maryland Park Service is pleased to announce an open house for the purpose of presenting draft concepts for a Trail Vision for Patapsco Valley State Park. The open house is scheduled for: 

Monday, April 20, 2015 from 6:00 p.m. to 8:00 p.m. 
Miller Branch of the Howard County Public Library (9421 Frederick Road in Ellicott City, MD 21042)

Saturday, April 25, 2015; 8:45 am - 1:00 pm  
Belmont Manor, Patapsco Valley State Park: 6553 Belmont Woods Road, Elkridge, 21075
Parking will be off of Belmont Woods Road.  Follow posted signs to event.

Learn to recognize wavyleaf basketgrass, a rapidly-spreading invasive non-native plant. Then join us for a short walk near the Belmont Manor in PVSP and help us map the location of any wavygrass we see. Volunteers can use the smartphone application developed by the Wavyleaf Mapping Project at Towson University, or can use a handheld GPS and submit their observations by email. Once trained, citizen scientists are encouraged to report sightings of the plant anywhere they notice it. 

The Wavyleaf Mapping Project, in partnership with the Patapsco Valley State Park volunteer coordinator, the Patapsco Heritage Greenway, Inc., and the Sierra Club, has the goal of mapping the wavyleaf basketgrass distribution throughout the entire Park in 2015. This is the first step to eradicating the plant and saving the native biodiversity of the Park. To register, go to

3:00 - 4:30 pm
Robinson Nature Center (free admission to the center for program attendees)
6692 Cedar Ln, Columbia, MD 21044

Citizen scientists are needed to monitor the health of our waterways. Rachel Beebe, of the Howard County Office of Community Sustainability, will demonstrate how to use the "Stream mAPPer" smart phone application to provide stream evaluations to the county government for assessment. 

The app brings together nature and technology, and is a great way to get outdoors and help officials monitor local streams.

Find the app for Iphone by searching “the stream mapper” in the itunes store, and for Android by searching “stream mapper” in the Google Play Store. See what people have already discovered with the application at
