Patapsco Valley State Park
RV Guide


Highly regarded as one of the best state parks in Maryland, Patapsco Valley State Park is a must-visit for RV lovers on the east coast. Named after The Patapsco River that runs right on through the valley, the park is very popular and attracts both locals and visitors alike who are looking to get back to nature.
Located only 12 miles from the center of Baltimore, Patapsco Valley State Park had the honor of being crowned the first state park in Maryland when it was officially opened in 2006. Before being designated as a state park, it was originally a forest reserve that opened way back in 1906. The park also made history by being home to the first Civilian Public Service; it was a place for conscientious objectors to serve in the military without fighting in the war.

There is so much to see and do at Patapsco Valley State Park that it won't be possible to fit in everything on your first trip. There are more than 16,000 acres of untouched beauty for you to explore, including over 20 miles of hiking trails, multiple water-based recreational activities, a disc golf course, and several picnic areas. The terrain of the park is mostly woodlands, but there are also plenty of diverse regions, thanks to the prominence of the Patapsco River.

For RV lovers wanting to stay at the park, there is one campground suitable that comes equipped with electrical hookups. There are also group, tent, and cabin camping options in the park if you are looking for something a little different. With adventures abound and much to explore, it's time to take in as much of Patapsco Valley as possible.

Getting to and from Patapsco Valley State Park is relatively simple since it is close to Baltimore. There are numerous ways to access the park with the most popular being via the Baltimore National Turnpike. Using the westbound entrance for most RVs will be difficult, so the majority of travelers recommend entering from the eastbound section.

Driving is the only fully connected way to get around the entirety of Patapsco Valley State Park since it is so large. Typically, being parked at the campgrounds means you won't be getting very far north or south of the park. These are two very different feels. The northern end is full of serene surroundings and is a bit quieter—great for hiking — the southern end sports all the historic sites and the iconic Swinging Bridge.
When traveling across the park, guests will find six distinct and unique areas. Patapsco Valley State Park's individual sections offer a plethora of services, amenities, and outdoor opportunities. With busy seasons come busy crowds; if any areas are full, you can always move on to the next. Each holds its own charm and scenic landscape. Parking can be found in all main areas of Avalon, Daniels, Hilton, Hollofield, McKeldin, and Pickall. Be sure to stop by them all before you see your trip through.

If you're staying overnight, you'll be parking your rig in Hollofield Campground. Parking can be a bit tricky, and somewhat tight for larger hauls. The campground hosts are quite gracious and readily assist guests with any issues, so you won't have to go it alone.

If you don't have any discs, you can ask staff members if there are any available for rent, but regardless, it will be a good idea to bring your own.

Accessible Hiking

Many come to the outdoors to get a taste of some excellent hiking, biking, and more. But, when you use a wheelchair, your options may seem much more limiting. Luckily, Patapsco Valley State Park is one of many state parks that has worked to keep as many areas as possible accessible to guests of all abilities. The Grist Mill Trail, situated in the Orange Grove Area, and close to the famed Swinging Bridge, is a wheelchair accessible, paved, wide, level path. This pleasant layout features cutouts along the way that go out to the river, and are great for exploratory visitors.

Trekking Across the Swinging Bridge

This point of interest is easily recognizable and is a destination you'll readily recall for years to come. The remarkable Swinging Bridge is an iconic area that visitors flock to experience. It actually swings, too — making this bridge a unique and fun crossing experience. As if the bridge wasn't enough, it's what's below it that is worth even more of the attention. The views of the Patapsco River are absolutely astounding from atop the bridge.



Hiking is one of the most popular activities in Patapsco State Park thanks to the 32 miles of hiking trails and over 200 extensive miles of multi-use trails. With so many options for trails, guests are sure to find one to suit the intensity they are looking for. There are many scenic areas to start your hike, ranging from the McKeldin area to the Avalon-Glen Artney area. Guests can explore the northern scenic biking trails and secluded retreats down to the rich history of the southern portion of the park.

Horseback Riding

The valley's impressive trail system crosses four counties and provides some of the most extensive hiking, biking, and even horseback riding opportunities. There are at least five trails across the park's expanse that allow for equestrian use. Unfortunately, the park doesn't have any areas for horse rentals, but visitors are free to come along with horse trailers in tow. There's nothing quite like following the length of the Patapsco River atop your favorite horse, so consider bringing your horse during your visit to the park.

Visiting the Playground

Another area of the park, dubbed the Avalon area, is the ideal playtime getaway for kids with a bit of extra energy. Maybe all that hiking and exploring has been quite enough yet? This colorful, eye-catching playground is a pretty choice among visiting kids. Climb, slide, laugh, and play until you can't anymore. Besides the play structure, an additional area with swings is also available that accommodates kids of all ages and abilities.

Bird Watching

The valley and state park are home to a vast community of birds waiting for you to admire. Most species to frequent this area of Maryland fall within the forest-interior dwelling species and shrubland species. There are several important watchlist species of birds that find solace in the Patapsco Valley forests and shrublands, so you may get to spot some pieces of nature that you've never seen before! Be sure to bring your binoculars in your camper to assist you in finding the birds hiding in the tall trees or distant shrubs. Hot tip: ask one of the friendly staff for their favorite birding areas, and you might get to witness even more activity.


During a hot summer day, there is no better way to cool off than by jumping in the Patapsco River for a swim. There are plenty of different areas for you to splash about at throughout the park, and nearly all of the river is open to swimming. One of the more popular swimming spots is in the Daniels Area. Here you will find a natural pool-like swimming area thanks to Daniels Dam. There is no guarantee that any lifeguards will be on duty during your time at the park, so take precautions when swimming.
