Description –

So last year, I was struggling mightily to get a new job.  I ended up with eight interviews in less than two months, some of them in far off corners of New Jersey.  After one of those interviews a good hour and half north of my house (I didn’t get offered the job), I changed out of my suit and hit a few trails on the way home including Sunset Park in Montgomery Township , Mike Merdinger Park in Hillsborough, and my target for the day, Sourland Mountains Preserve.  I’d heard a ton about the park and how awesome that it was, so I was excited for this one!

Unfortunately, it was raining when I got there.  So I went home.  HA!  Of course not, it was hiking time!  I parked in the empty lot and headed up hill on the Ridge Trail hill into the woods.

Into the woods!
Rocks? Who has rocks? Answer – not South Jersey.
I am a sucker for a bridge.

So the hills here probably aren’t bad, but it was a bit wet, and I do live in one of the flattest places ever (South Jersey), so I have to admit there was some huffing and puffing going up the hill.

I love these roots.

Up, up, up

Found a balloon! Not sure which number this was last year.

Eventually, I dragged myself to the top of the ridge and one of the highlights of the Preserve, the Devil’s Half Acre Boulders.  It was very misty and creepy up here, as well as, you know, bouldery, so I enjoyed hiking through the clouds.  Also, I enjoyed not going uphill very much.



Make new friends!

Now I was REALLY enjoying this hike, but I’d (oh boy, this is embarrassing for someone who runs a hiking blog) had forgotten to put a water bottle in my car before I left that morning.  On top of that, I realized I was running short on time.  So when I came to the intersection of the Ridge Trail, the Roaring Brook Trail, and the Connector Trail, I made the sad choice to turn left down the connector trail.

Making the turn.


Staying left to stay on the connector trail.

Man, I love little bridges.

Now when I reached the bottom of the hill, I realized I wasn’t THAT thirsty and I didn’t have to home THAT soon.  So I made the right turn onto the Maple Flats Trail to take the long way around to the parking lot.  It was a touch muddy from the rains, but not that bad… adventure!

The trail eventually reaches a road.  Left provides a nice view down the hill.

I opted to head right, as the Maple Flats Trail followed the road uphill for a short stretch, then turned left off of the dirt road.

Pretty flowers on the way up.

Once past the road, the Maple Flats Trail loops around and meets up with the Ridge Trail.  I could turn right to take the Ridge Trail up to Roaring Rocks, but I opted to stay left and follow where the Maple Flats Trail and the Ridge Trail overlap.  It met up again with the road, only lower down the hill.

Recrossing the road.

From here, the trails work their way back to the parking lot, passing a lovely little pond right by the parking lot.

Right toward the parking lot.

Ending at a lovely little pond.

I ended up at the car after a lovely 3 1/2 mile loop, tired and thirsty, but thrilled with the adventure.  I will be back to head up to Roaring Rocks Boulders!
