Getting weather forecast...


Several boulders/cliffs spread throughout the forest surrounding Cedar Lake, in Denville NJ. The area is split into a few separate sections, each being around a 5 minute walk from the last. The spots are nice and shady, but in the summer will still be uncomfortably hot and humid. As of now, only a select few climbers know of the location, so all bouldering establishment has been done by 2 or 3 people. The rock itself differs between areas, but it's mostly sharp and crumbly. Expect a few of the problems to hurt.

NOTE: I've heard a few climbers have been around to check out these rocks. It would be awesome if those who have been here or plan to check the spots out make note of ascents, and help with the grading and rating of the problems! Currently the areas are only being established by 2 people, so the more climbers the better the area becomes.

Getting There

You can access the boulders from Cedar Lake East. On the drive in, you will pass a beach on the left, then continue on up a gradual hill. You'll climb a steep hill, then begin descending quickly. The road will make a sharp left turn. Midway through this turn you'll see a straight driveway directly in front of you lined with small pine trees. Approach this, and turn right into a small unpaved area big enough for 2 cars. This is the main entrance to the woods/trail system.

I was unimpressed with this area. I'm always looking for small crags in the area with some (relatively) quality boulder problems. I visited the "Hog's Pen" area today. After a little bit of wondering, I arrived at the crag only to find a "frat retreat," if you will. It was frat camp out and they set up shop right in the center of the bouldering area. The lower area looked really chossy and had really poor rock quality so I walked up further. The higher wall seemed like it was better rock quality, although probably more suitable for TR than bouldering. Anyway, I did a couple v0's and v1's, some highball. I broke two holds during the process and almost came crashing down. I was kicking off footholds on my way up the problems. After almost falling back into a talus field after pulling off the second hold, I decided it was time to call it quits Maybe the other areas are better? Not sure, but the combination of poor rock quality, moderate problem quality, and a 20 min approach, I wouldn't recommend this spot. There are many other low-key bouldering crags in the area with much higher quality rock/problems. Apr 5, 2014

Jon- Did you get on problems listed or just jump on whatever? As any barely traveled area, the rock will have loose blocks and breaking footholds if it has never been climbed before. Some of the problems posted here on MP (Pac Man's Lunch, Uptown Arete) have seen multiple ascents and are super fun for NJ standards. Maybe you missed them...

Either way, if you know of other secret spots you would rather spend time at, then by all means travel there. This area is just posted to let other NJ climbers know of some stones they can get on in this rock-deprived state. Apr 6, 2014

I did follow the beta listed here, but I had trouble identifying specific routes. I think I got on the two you named as well as "Fanger Slapper." Is Fanger Slapper on the boulder that has the fire pit up against it?

Of course I understand that any area that is being newly developed will have some loose holds and blocks. I just felt like the rock quality was significantly poor relative to other crags in the area. I really appreciate that you guys took the time to post beta on this spot and expand the knowledge base of bouldering in NJ. I've been hesitant to do the same because many of the spots I frequent are access sensitive. PM me if you want to exchange beta on some local spots and get out sometime. Apr 8, 2014

Jon- Unless they built two fire pits, fanger slapper is a problem further up the hill! I wouldn't touch the fire pit side of the slanted boulder. But regarding local areas, I would love to give them a look. I'm in the Adirondacks until late May but I'll shoot you a PM around then Apr 9, 2014

I was exploring Jonathan's Woods this past week where the Cedar Lake boulders are located. About 100 feet west of the boulders described in the Hog Pen is a cliff that is probably like 30-35 feet and is now covered in about 20 or so bolts. Does anyone know what we're calling this cliff and if these bolted routes are documented? When were these bolts added? I see no mention of them on this page. Thanks! Dec 29, 2017
