Written Directions
PA 259 is directly off of Route 30 between Lawson Heights and Ligonier. Although it's terminus is PA 422 anything north of PA 56 is boring. So it's starting point up north, that's worthy to be ridden, is PA 56 intersection east of Homer City, PA.
Scenery
This is a valley road in the south, for the most part. It does cross some hills, but you get some nice views of the hills on both sides of the road. North of Bolivar it opens up and you been to sweep on tops of hills with more of a residential feel.
Drive Enjoyment
North of Bolivar, PA the road is a solid 3.5 to 4. South of Bolivar, however, the road is pretty disappointing. Patch work here and there, dirty, horse manure. This road could really stand to be paved, and in doing so would bump up the fun a good deal.
Tourism Opportunities
Get your gas and food in Homer City or Ligonier because there aren't really any towns short of Bolivar (which isn't a big one) on this road.
Motorcycle Road Additional info
Nice scenic, semi-twisty, poorly to averagely paved road. A decent one if you're in the area. Nothing I'd go out of my way for, though. It does have potential, though...
