The Patapsco River runs right on through the valley, providing an appropriate companion to the state park's forested landscape. Patapsco Valley State Park is a Maryland destination where you can really feel like you're getting away. The park hosts a variety of outdoor opportunities and several unique areas to enjoy.

RV visitors won't want to miss out on an opportunity to see the Cascade Falls, check out the Swinging Bridge, go disc golfing, explore the park's many multi-use trails, and partake in other outdoor park activities. With a tons of activities to keep guests busy during their stay, you'll be glad you can park your camper in the park's Hollofield Campground. With adventures abound and much to explore, it's time to take in as much of Patapsco Valley as possible. There is so much to do here from boating and tubing to snowmobiling and rock climbing.

The park's 16,000-acre expanse makes it rather difficult to fully cover unless you have the aid of a vehicle. None of the park's trails fully loop around, north to south, so the only way to reach the entire length is to go with the aid of four wheels. Whether you set aside time before making camp, or to wrap your RV trip up, you won't want to leave this piece of the East Coast without seeing it all. When you take the scenic route in your motorhome you're likely to discover even more fun.

Transportation in Patapsco Valley State Park


Driving is the only fully connected way to get around the entirety of Patapsco Valley State Park. The park's extensive pathways for biking, hiking, and horseback riding provide several loops and winding trails to take in the scenery but don't allow visitors to access all sections fluidly. There are several sections you'll want to visit, while with the aid of all four wheels, before completing your stay. 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.

Just be mindful of vehicle height. If your rig stretches over 11 feet, you won't want to make your entrance westbound on Route 40. Instead, take the advice of many other travelers, and go eastbound on Route 40. Also, remain at the check-in hut upon arrival.


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.
