Grove Run is a loop that in either direction it is the steepest and most technically challenging descent and climb at Laurel Highlands.
Counter-clockwise: From the end of Fish Run, make a right. You'll be in for a very rocky, but manageable descent. On your way down you'll cross over Quarry Rd and eventually end up in Linn Run Campground. Make a left and follow the campground road to get the next section of Grove Run. This section will be a switchback climb that is rocky and narrow. At the end of your 1.75 mile climb, you'll have a choice on how to return. You can go straight across Quarry Rd and make a right on Fish Run Tr to double back Fish Run or make a right on Quarry Rd, then a left on Weaver Rd and a left on Hickory Flats Rd to get to the top of Linn Run Rd. A right on Linn Run Rd will take you to Wolf Rocks Parking lot in less than a mile.
Clockwise: From the end of Fish Run a left is made on Grove Run. In less than 1/4 mile you cross over Quarry Rd. Be prepared for a rocky descent that will include tight switchbacks, rocky stream crossings and benchcut singletrack that is very narrow. After a 1.75 mile downhill you'll enter Linn Run Campground. Once in the campground you'll have to carefully watch for the continuation of Grove Run Trail on your right. When you find the trail, be prepared for a tough climb. Initially the rocks may make it challenging. After crossing Quarry Rd you'll hit uphill rocky sections, however, these are short lived. You'll eventually end the loop back at Fish Run Trail
. From there you can make a left and double back Fish Run or go straight and make lefts on Quarry Rd, Weaver Rd and Hickory Flats Rd to get to the top of Linn Run Rd. A right on Linn Run Rd will take you to Wolf Rocks Parking lot in less than a mile.
