Please read what our campers and visitors are saying about Patapsco Valley State Park: The new paving is great in the Hollofield area campground but most of all the Rangers are amazing. Helpful, considerate and friendly.You make the guests feel welcome. One ranger came to our campsite with a partially blind bird and spoke to us for quite some time about the bird. The first day back to school, it was all one of my daughter's could talk about to the other students.
