I had an absolutely lovely time camping here. The sites were level and well maintained with fire pit and picnic table. About a third of the sites are cabins and the rest are flat camping areas. There is a playground at one end and a place to take trash and recycling. The bathrooms were located in the center and a short walk from anywhere in the campground.

About a third of the sites are cabins and the rest are flat camping areas. There is a playground at one end and a place to take trash and recycling. The bathrooms were located in the center and a short walk from anywhere in the campground. The facilities were very clean with plenty of stalls and hot showers. You can technically hike all the trials in the park from this campsite, but the trails on the southern end of the park take over and hour to hike to. It all depends on your hiking ability. The trails around the campground were lovely.

Great camping experience. The sights are well maintained and it is very secluded. The park staff is super friendly very helpful. Each sight has a table, fire pit and a small cook work area. Bathrooms and showers were very clean. We had a blast.

This campground is exceptional. The staff is generous. It is hard to imagine you are minutes from the hussle and bussle of city life. The bathroom is so clean - and the (locked at night) front gate gives an extra feel of security,

It's kind of convoluted to get registered, which cost everyone involved some time and some patience to get sorted initially. This is mainly because their website is set up with more restrictions than simple accommodations. Some of which overlap and conflict with each other in a way that makes booking online somewhat harder than it should be or that may be practical. That is to say you can't book...

This is mainly because their website is set up with more restrictions than simple accommodations. Some of which overlap and conflict with each other in a way that makes booking online somewhat harder than it should be or that may be practical. That is to say you can't book 24hrs out or on the same day, but they also require a two-day minimum stay. For me this meant that while I was planning on arriving on Friday for a two-day stay, I could not get past the two hurtles required to pre-book on Thursday and instead had to wait until I arrived on Friday before I could get registered or pick my spot. Outside of that bit of logistics chess, it is a nice campsite however, run in person by very nice people in a great setting, also surprisingly close to the city of Baltimore and all that has to offer.

Absolutely lovely place to camp in the middle of dense suburbia! Quiet, peaceful, and filled with wonderful hiking trails, & places to swim.
