From the parking area, walk south on Route 9W for a few hundred feet. Just beyond road signs for Routes 9W and 202, you’ll see three blue blazes and three red-dot-on-white blazes on a tree adjacent to the road. These blazes mark the start of the Timp-Torne (blue) and Ramapo-Dunderberg (red-dot-on-white) trails. You’ll be following the Timp-Torne Trail for the first part of the hike and...

You didn't do the loop that I described
The hike description states (fifth and sixth paragraphs):  "The curved roadbed ends at the opposite end of the uncompleted tunnel, but the trail bears left, crosses a stream and reaches a woods road. Turn right and follow this road, known as the Jones Trail."  You're supposed to turn right, immediately after crossing the stream, onto an unmarked woods road (which is shown on Trail Conference Map 119 and labeled as the Jones Trail). Instead, you continued for another mile and a half on the Timp-Torne Trail and then turned right onto the 1777 Trail.  The longer loop that you actually did is described on our website (in the opposite direction) as a separate hike: www.nynjtc.org/hike/dunderberg-spiral-railwaybald-mountain-loop , and it is indeed about 6.8 miles long.

Did I do the correct loop?
My son and I just did the loop above (or at least i think we did).  We entered on Ramapo trail, turned left on Timp-Torne,  cut over at the 77 trail (which based on it being the only crossover trail connecting Ramapo and Timp, i assumed it was that jones trail the description discussed).  Then we looped back on the Ramapo trail.  It was 6.8 miles, and extremely difficult terrain. We did the Breakneck Ridge trail and this was at least as difficult, especially on the way down.  The ground was all medium sized loose rocks (for like 1/2 of the descent at least) and the descent was very steep .  Not only did it do a number on my knees, but it was rough even for my teenage son who is extremely fit.  The info above says 3.9 miles and I mapped it at 6.8 miles (using map my hike app).  Did i do the correct loop, or did I misunderstand?
