Bradley Palmer State Park Professional Review and Guide
"As far as the trails go, they are friendly to bikes. The hard dirt surfaces allow tires to hook up well, and climbing is just a matter of moving the cranks. The hills here, Blueberry and Moon Hill, are not too tall. They have some nice paths downhill that resemble wide singletrack and wind around the face of the hills. There are a few trails on the face of Blueberry Hill that are overgrown with thorn bushes, but downhill options are plentiful, and the majority of the riding is on wide, flat doubletrack.
The flat doubletrack covers over 720 acres and winds around the park like a giant maze. The main thing to understand is that most of the trails intersect with another path or the access road at some point. Residential streets surround the entire park. This makes getting lost possible, but not too likely. The park's trail maps are fairly accurate and were last updated in 1998. Terrain: Packed-dirt doubletrack bridle trails, sandy fire roads, paved access roads, and some thin, rocky doubletrack trails."
