Welcome
@DSide.
Parts of Long Valley (LV) may be a bit far for regular rides into Stephen's State Park, and depending on location in LV, could be a big uphill ride back home.
I don't think there is very much riding at Schooley's Mountain park, certainly not enough to make it a destination park, but maybe a ride around to get your wheels on dirt. But if you link Schooley's Mtn. with Patriot's path, it could give you a mix of Patriots path riding and some single track.
On days when you are willing to drive to a trailhead, the good news though is that you would be a relatively short drive to Kinney Rd in Stanhope where you could ride into Stephens, Deer Park or Allamuchy and combined this Allamuchy Mountain area is over 9,000 acres.
Also, the Nassau trails near High Bridge are not too far a drive from LV either.
