There are signs for the range right at the intersection of BVR and Taylor rd. Last year when I was there, it had 4 targets. up to 35 yards. The State owns the property. there is also a parking lot there. its behind the one (P) let me know if you guys find. http://www.state.nj.us/dep/fgw/pdf/wmamaps/rockaway_river_so.pdf
I'm Glad you found it, not many people know about it. The only draw back is the BUGS, If you get a chance take a walk up to the first ridge to the right of the range. had trailcam pics of a Good 8 pointer there last year. Hopefully he made to this year.
