The Hollofield Area of Patapsco is located almost in the center of the Park along Rt 40 (Baltimore National Pike). Home to Park Headquarters and one of two campgrounds in the park, this area has one of the most stunning views of the Patapsco River Valley. The Overlook changes with every season from the brilliant greens of spring to the rich colors of fall. The Patapsco River Valley shows its full beauty in every season from this vantage point. This area is perfect for a family gathering or a quick picnic lunch while on your lunch break from work.
Trails such as the Old Ranger Trail or Peaceful Pond trail provide a quick respite or workout in a beautiful setting just minutes from the hustle and bustle of Baltimore. Anglers can gain access to the river by following Union Dam trail down to the river. Our campground is a little piece of wilderness in the middle of suburban Baltimore. While occasionally you can hear the buzz of cars along Rt. 40 or see a nearby neighborhood through the trees, you really feel like you’re away from everyday trappings enjoying the great outdoors when camping with us.
For those of you who might use this as your home base when on vacation, we are minutes from several exciting attractions in Baltimore and Washington D.C. Our picnic shelters in this are CCC (Civilian Conservation Corps) built structures. Built during the Great Depression, as America worked to get people back to work, the craftsmanship in these shelters reflects the pride of work and the true skill of the men who built them more than 80 years ago. When you visit the Hollofield area of Patapsco, marvel at the rich history of this park and kick back and enjoy a little slice of the great outdoors.

Hollofield ( Things to do )
The river is accessible from Union Dam Trail and River Ridge Trail. Fishermen may also access the river where Old Frederick Road crosses the River. A dirt parking area adjacent to the bridge and railroad tracks provides parking for fishermen wishing to use this area.
Unguarded swimming is permitted at your own risk all along the river, except where posted as closed. The river can have strong currents – use care when swimming in these areas.
This area provides a sweeping view of the River Valley. This is a perfect place to view the changing blanket of the seasons. You can see historic Rt. 40 Bridge to the North. You can see the River peek through when the leaves fall from the trees in winter. In the Spring new green leaves blanket the valley and in Fall the patchwork of color provides one of the most spectacular views of the Patapsco River Valley.
The Hollofield campground has 73 campsites, some with electric hookups. Each campsite has a picnic table and a fire ring. All equipment must be positioned on the designated camping pad and driveway.
Note – Campers whose units are over 11’1” in height must enter the park by the Route 40 East Entrance.
Camp Hosts are there to assist you during your stay. They can provide information on the park, assist you with emergencies, and provide you with guidance on campground rules and regulations. Camp Hosts are Volunteers. They may spend the entire season or at minimum one month with us. Check out our Volunteer opportunities for more information on the camp host program.
