Fun up & down trails.

Great Trail, hiked it with my son for the first time. Lots of icy patches due to the recent rain but overall a great trail!!!! There was a race event going on and had fun cheering on the runners!!

well kept trails, can be muddy, lots of dogs, trail runners and bikers. I came during the winter and it was fine

11/2/18. South Mountain Reservation is almost in my back yard and I've hiked it very, very often, I had not however (until introduced to it by All Trails) ever hiked this particular combination. An easy 4.5 mile hike that can be done in approx 1.5 hours — one feels like a Parisien Boulevardier on 10' wide trails for most of the hike (with the exception of the Lenape trail which is narrower and twistier). Fall colors make it feel like a sepia photograph. As others have noted though, with the exception of the Lenape trail (yellow), it is VERY poorly marked and I don't recommend doing this without the GPS on in the All Trails app.

Very fun hike but it would have been impossible without GPS and the AllTrails app, because there are almost no markings on the trails. Even with GPS and the AllTrails app, finding our way was difficult at times. Sometimes we would just start walking where the trail was supposed to be and it would eventually materialize. That said, while South Mountain Reservation is often crowded, we were hiking alone, which was great, on much of this route — probably because no one else knows about or can find it. Interestingly, the trails themselves are mostly in pretty good condition, so someone is clearly handling the upkeep — just not the markings.

Our dog loved it!

An easy trail that may get you lost towards the end of the outer swamp trail. overall it was a fun trail with nice view of the two waterfalls and other scenes. A nice breezy trail to do.

It’s a nice, local spot with a small waterfall. Trail markings are difficult but if you know your way, it’s possible to stay off of paved roads and in some beautiful wooded areas with nice creeks. Great for our dog and 5 year old daughter.

The beginning of this trail was disappointing, lots of trash and two used condoms within the first mile (pack out what you pack in, people!). Seems like the trailhead is a local hangout. The trail was more Rocky than I was expecting and quite challenging towards the back half with significant uphills. That said, I had about 45 pounds on my back (I carry my two year old in a kid carrier during hikes). Once we were in a little further it was quite nice and quiet.

Great trail but not well marked everywhere. Hard to follow without a map or if not well familiar.

Awesome! 6 miles saw hemlock falls. Great hike, saw some cool things along the way too. Many different trails and parking on locust grove in millburn

Really nice trek. I was able to manage it as a first serious hike with my 7 year old daughter.
...A friendly dog stole her walking stick.

It is a beautiful place away from the city. Not a long drive. You can hike and if you need there is a nice waterfall you could take dip in a nice summery day. Hike along the waterfall.

Very nicely kept trails, decent difficulty. Only problem was the high traffic. If you're looking for privacy, not the spot

Easy to moderate trail. Kind of confusing. So-so of a good view. Definitely recommended for beginner hikers and for anyone who's looking to sweat and a work out.

great. easy to follow with this app. only negatives are that there are many people at certain points and you can see the road for about 1fourth of the route.

The trails at south mountain are amazing. Perfect proximity to the zoo, shopping, freeways, parking, it also has a great overlook loop on south side of the reservation. Wide and graveled mostly, easy to walk with a group or the family. Enjoy it!

Nice loop through the woods. Suitable for kids too. Not too crowded.

Beautiful place to hike. A bit rocky in parts, but then smooths out and is an easy to moderate hike.
