Take the combined Hoeferlin (yellow blazed) and Cannonball (red blazed with C in middle) trails to the top of the hill. There, a short, unmarked trail will lead you to Matapin Rock.
The trailhead can be caught at the end of the guardrail adjacent to the parking area at N41.03.592,W74.15.059.
It's a short walk to a nice overlook. The cache is hidden nearby.
For those looking for a longer hike, make this part of the Hiker Series. If you'd like to do this, here is the recommended route. If you do, it's an excellent hike that should take you 4-6 hours to complete.
Park at the upper parking lot on Skyline Drive. You will see the orange blazes for the Schuber Trailhead across the street, near the Camp Tamarack sign. Starting at the Schuber trailhead take it to Cache 1, then on to the white blazed Millstone Trail and Rocky Slide Gulch for Cache 2. Continue on the white (Millstone)trail to the yellow trail, cross the road then on to cache 3.
After finding Cache 3, continue on the Schuber/Yellow trail, then make a left left onto the Old Guard trail (white blaze with green leaf in center) and continue to Cache 4. After finding cache 4, continue on the Old Guard trail, cross the pipeline cut, then the Cannonball (red w/"C") and Hoeferlin (also yellow)trails.
You'll then reach the escarpment, where you will see nice views of the Wanaque Reservoir through the trees. Here the Old Guard joins the red blazed, Ringwood Ramapo Trail. Follow it to Cache 5. After finding this one continue on the the Old Guard. You'll cross the Hoeferlin again and reach the Cannonball for the second time. Make a right here and head to Cache 6.
The Cannonball soon joins the Hoeferlin and they eventually cross a gravel road together and cache 7 is close by. They then reach Skyline Drive before heading back into the woods beyond the yellow gate. After passing the gate, continue on the Hoeferlin/Cannonball. The Cannonball will split to the right. Stay on the Hoeferlin and take it Cache 8, then back to your car.
