Simple, heavily wooded trail - a dumbed down version of the more scenic outer loop. Good for someone looking for a quick hour hike!

Great hike. Good diversity. Probably the most challenging you’ll get in Hillsborough area.

Much steeper and rockier than I thought. Lots of fun. Depending on the path you choose, not at all appropriate for dogs! Also, not as well indicated as I would have expected. Thank goodness for all the "donation" signs on the trees!

Let's face it, there is not a lot of elevation to be had in the middle of Jersey. Clayton has some fun hills and the Yellow Trail at Baldpate will get your heart pumping a bit, but the Sourlands have quickly become my "local" favorite. Rocky, but very nice trails, not overgrown at all, even mid-summer. Odd system for marking trails, and marked pretty well... for the most part. I always seem to lose the trail at the top North corner, by the boulders. People seem to wander around and explore in this area a lot so a distinct trail is no so easy to follow. Fortunately, its pretty difficult to really get lost, just head downhill. There are a lot of options for distance and difficulty. Overall, a great place, but beware, the lot gets very full, very fast on the weekends.

Very nice and somewhat vigorous trek through the Sours. Just enough traffic to break up the still of mid day with some pleasantries of conversation from a passerby. Delightful yet energetic afoot in these hills. ☮️

This trail was perfect for a beginner hiker like myself. Very easy to stay on trail and have cell service throughout. Very forested atmosphere with nice scenery. However, I was hoping there would be a nice view at some point on this trail but there was none. Would recommend.

This was a fantastic hiking trail. I love to climb on some rocks so this was great. Be sure to have proper footwear since there are so many rocks you can easily twist an ankle. Also, if you bring a dog be sure they have taken tick treatment. Our dog does and when we got home there were over 12 ticks on him. Besides that, I loved the trail!

One of my favorites in the area! Often crowded so get there early. Bring a map printout with you as recently I haven't found the map boxes to be refilled and it's easy to get lost on the trails here. Very popular spot for mountain climbers since the boulders are perfect for free play! All around a nice location, serene spots, and a wonderful place for a day hike.

Probably the best place to train for M.U.T. running near central jersey, often crowded.

if you don't mind hiking and climbing over huge rocks for 3 hours then this is a nice hike. the forest is lush and beautiful. there are no Vistas or overlooks. there are lots streams and Brooks. unfortunately we went at the beginning of fall 2016 every stream and brook was completely dry due to a drought. there are a lot trail marker but they are none traditional. the marker don't give direction when the trails turn start and end. we got very turn around twice at connector trails.

A bit too rocky for a good trail run, as the rocks are a big jagged and it's hard to get a good footing. Would have preferred it as a hike. Ran into a very large black snake, which was a bit of a surprise. I will say that if you take the pipeline trail down, there are hundreds of butterflies to be seen at this time of year, all enjoying the amethyst colored thistles.

it's a good walk, rocky in some spots for no reason whatsoever though. not all that much in the way of scenery but the foliage would be nice, I'm sure.

Very nice! Trail needs to be marked better, can be confusing at times.

I had a great time hiking with my kids. The trails were well marked, I will definitely go back!

For Somerset County this is my family's favorite hike. The rocks are always a lot of fun.
