We had a wonderful time camping at Susquehanna State Park. The campground was peaceful, with spacious, shaded sites, and the bathrooms were impressively clean and well-maintained – a big plus when camping. We hiked the Green Trail, which was scenic, well-marked, and relaxing. It’s not too difficult, making it enjoyable for families, but still gives you that quiet, immersed-in-nature feeling. The... We had a wonderful time camping at Susquehanna State Park. The campground was peaceful, with spacious, shaded sites, and the bathrooms were impressively clean and well-maintained – a big plus when camping. We hiked the Green Trail, which was scenic, well-marked, and relaxing. It’s not too difficult, making it enjoyable for families, but still gives you that quiet, immersed-in-nature feeling. The park has a good variety of trails, so there’s definitely more to explore if you enjoy hiking. This park is also very suitable for biking, with several trails and paths that make it fun to ride while taking in the natural surroundings. Between the hiking and biking options, you could easily spend a few days here without running out of things to do. What makes Susquehanna special is its historic character – the old buildings and preserved sites give it a unique charm that adds to the overall experience. Overall, this is a great spot for anyone who enjoys camping, hiking, or biking, with the added bonus of history all around. We left refreshed and are already looking forward to coming back.

I loved this park for camping, hiking, the history (Steppingstone Farm Museum and other buildings), and access to the river. Nice campsites, super clean bathhouse, and helpful, non hassling rangers.

Campsite was perfect! Tucked back off the loop, close to the bathrooms which were clean and had working hand dryers and soap. Cool October evening, plenty of dead wood to keep the fire going. Only thing that was a negative was the train whistle all night next time I’d rock with some ear plugs for sure. Would stay again.

Stayed here for 3 nights with our 22 foot travel trailer. Initial impressions weren’t great, check in was 3 pm but we arrived around 1:30 and they still wouldn’t let us go to our spot even though it was empty.

Stayed here for 3 nights with our 22 foot travel trailer. Initial impressions weren’t great, check in was 3 pm but we arrived around 1:30 and they still wouldn’t let us go to our spot even though it was empty. So we then had to drive around really narrow roads to find a place to hang for the time. It was 90 degrees so not fun and the map was not good enough to determine where we could take our trailer. There is also virtually no Verizon signal in the park, maybe 1 bar so our booster was able to give us enough signal to look at the weather and check the Internet but no streaming. Also the park is not very well maintained, many low branches for a 10 foot tall trailer. There are only 7-8 sites with electric, water was only available at the different spigots but we were able to hook up to one before we parked and fill our fresh water tank. Not all of the electric sites are good for an RV. We had site 60 which was very well suited for an RV/trailer (even bigger than ours), plenty of room and lots of shade. Bath houses were standard for a state park. The dump station was sufficient although it’s narrow and they could put some more pavement so that you can not drive over the actual dump location. We were only here for a family reunion but the trail system looked nice and access to the river was available. Lots of bikers and kayakers.

Bathrooms were clean and well equipped, that was the only likable thing. The playground was boarded and fenced off. Someone playing very loud music late on a Thursday night, and no one around to do a thing about it. Guy running a generator in the “no generator” area. Picnic tables in poor condition. People driving way too fast for a campground. Trash around the campsites at arrival.
