Crystal Springs
47-51 R, Washington Township, Morris County and Lebanon Township, Hunterdon County, New Jersey


(From Route 78 East/West or Route 31 North from Trenton/Flemington) From the Route 31/Route 78 Interchange, proceed on Route 31 North for approximately 6 miles. You will go though 5 traffic lights. (You will also pass town boundary signs for Lebanon Twp and Glen Gardner. Shortly after the 5th light in Glen Gardner you will see a red McDonalds billboard straight ahead. Slow down because you will be making a sharp right hand turn onto Main Street, Glen Gardner (a short distance beyond mile marker 38 on Route 31) and just before this billboard.

Make this right onto Main Street, which is unmarked. (Again, it is a very sharp right turn, and there is a large farm and barn at the corner). Proceed on Main St. for 1/2 mi. and make a left onto Hill Rd (628). Go through the tunnel and follow the road for 5.5 miles until it ends. Now make a left onto Sliker Road and proceed for .9 miles. Make a right onto Pleasant Grove Road

Proceed up Pleasant Grove Road for 2 miles. As you drive along Pleasant Grove Road, you will pass various marked entrances to the Mountain Farm/Teetertown Ravine on the right. Do not turn into the park, but rather proceed straight along Pleasant Grove Road, which becomes Califon Road at Morris County line, until you reach an intersection with a residential street marked "47-51 R" (2 miles from the Sliker/Pleasant Grove Road intersection), or shortly after the Centenary College Equestrian Center. Make a left onto "47-51 R".

Proceed down "47-51 R" through a new development for about .1 mile. At this point, the pavement ends. Drive straight, on to what now becomes a dirt road. This is the entrance to the Crystal Springs/Pelio Property.

6/04/2005.  Rosemary Cooney, Ceferino Santana, dog Sonar and I went for a walk.  After touring Teetertown Ravine, we drove north on Pleasant Grove Road into Morris County where the road becomes Califon Road.  0.3 of a mile north of Middle Valley Road, we turned left onto 47-51 R Road.  We drove past the McMansions and onto the dirt road.  We continued until a chain crossed the dirt road and parked nearby.  We crossed over the chain heading west and walked along the dirt road.  We passed a pond on the left.  We then came upon an abandoned farm building with silos.  Near here is a fork in the road that heads uphill (we did not follow it).  We came to another pond, also on the left.  Next along the road were a second and third abandoned house.  Turned left heading south, leaving the dirt road.  The path heads along the second pond.  Reach another abandoned house.  A fellow is fishing for bass.  This is where the trail sort of officially ends because from here it is hard going.  The sides of the pond are very wet and it is no easy matter to walk farther with just tennis shoes.  We did it for awhile, but the gang did not like it.  So we turned back.  Dr. Patrick L. Cooney
