Swallow Falls has a great loop trail where you see four waterfalls. You can walk to the loop from the campground. It ma be adds a third of a mile to the hike.
We stayed in cabin 58, which has a short, easy path to the bathhouse and even shorter to the mud sink. This was very handy when traveling with two young kids. Prior to going, I wished I could have seen the inside of the cabins, particularly to know how big the mini fridge was. I couldn't find any pictures, so here they are.
It is a one-room cabin, was impressively clean, and the beds were very cozy. There are blackout curtains on the windows, so we slept late and it was glorious. There is one small window in the door that does not have a curtain. I taped aluminum foil up over it.
Each bed had a mattress pad on it when we arrived, as pictured. One minor note is that the bunk bed mattresses seem to be a bit too big for the bunk beds. This caused them to not lay perfectly flat and also made me feel uncomfortable having my roly-poly kids sleep on the top bunk, where there were only a couple inches between the mattress and the top of the railing.
I have Verizon and could make calls, but could not reliably send or receive text messages and there was no data access.
Great park. Great cabin. Great stay.
