Park Information

The Avalon and Orange Grove areas are within the southern end of Patapsco Valley State Park. The primary entrance is located off of South Street in Baltimore County. Avalon, once home of the Avalon Nail and Iron Works, has only a few remains of the bustling mill town that once dotted the shores of the Patapsco River. Today, this section of the park has large picnic shelters, playgrounds, and access to trails that travel through the river valley as well as up and out of the valley. You travel through Avalon to reach the Orange Grove area.

Orange Grove is one of the most scenic areas of Patapsco, once the home of the village of Orange Grove, a mill town that supported the flour mill on the Baltimore County side of the river. A swinging bridge similar to the one that spanned the river in the 1800’s and early 1900’s crosses the river today connecting guests to the popular Grist Mill Trail. This area provides access to picnic shelters and picnic sites, as well as access to several trails located in this section of the park.
