Hiked this trail today for the first time. Spent about 3 hours. Started at the Alpine street park. it's a nice size lot holding maybe 18 cars, but by the time I returned it was full and several cars had to park on the street. From parking lot hiked orange to blue, to yellow looping back to blue (to walk a section previously hiked) to red (follows the ridge back) and brings to just above the popular large boulder formation where you pick up orange again to return you to the lot. Very well blazed besides a few head scratching sections near the power lines. A mix of mostly hikers with a few mountain bikers.

This was a great trail/hike! The fall colors were beautiful, huge rock formations, uphills, downhills, small creek crossings, and several more connecting trails to explore. My dogs and I will come back again for sure!

Very technical mountain bike trails. Built by local riders for hikers and riders. Lots of great rock features and most fallen trees are left in place. Can ride up to 12 miles if you can find the tunnel under Interstate 78 and include the Cistern Park trail system.

It's a really scenic hike with enough rocky and narrow parts to make it challenging in a fun way. There isn't a ton of things to look at, but there's a few large rocks about halfway thought that are fun to climb or at least sit on for a break. There's also a stream with a wooden bridge over which I found kind of neat. The markings were easy to follow despite the orange trail crossing paths with other trails.

The orange trail was nice and well marked, however, I got off track when trying to do the red and blue trails. Luckily getting lost is certainly not a matter or life and death since you are in the middle of a city! I came upon route 309 and I knew I was off track and back tracked my way back to the orange trail. Still a great afternoon and I will return to figure out the other trails another day.

Fun challenging hike. Pretty rocky spots that make it difficult enough to be fun but not too hard. I wouldn't try it on a bike.

This place is GORGEOUS! If I have only know it was here for years. Took the orange trail and the beginning looked like a rainforest with the Rodale Run. Nice and easy hike but so much to look at...a Wonder in the middle of emmaus.

Great trail and loved the hike up the orange trail and into the blue followed by some red. The kids even enjoyed the hike. It was perfect for our first hike.

Went jogging with snow covered on the ground, it was a bit muddy and damp at the lower portions. It was fun with the quick inclines and declines on the Orange trail. Very refreshing and easy to follow markings.

Quality trails friendly people. Nice views in winter. If you only hike the orange trail it's 2 miles. Add other loops to increase​ distance. Recorded track looks like hikers added Red Loop.

Started at the Alpine street entrance and took the orange trail to the blue trail, blue to the red, and then red back to the orange trail. We logged about 4 miles total. There wasn't too much elevation gain. It took us approximately 2 hours. Overall, it was a very nice hike.

Enjoyable narrow ranged switchbacks and mountain terrain

Started at the Robert Rodale Gateway trail at the parking lot on Klines Rd and then picked up the orange trail. It had just rained the past two days so the trail was muddy/wet which made some of the rocks/wooden structures a bit slippery. The trail is designed for mountain bikes but I had no issues hiking it with my two dogs. Overall great little hike and I look forward to going back to explore some of the other trails that branch off of it.

My fiance lives in Emmaus and when I visit I really enjoy hiking this trail. Fine to do in shorts and sneakers. Really a nice peaceful walk

I work two jobs and have a 3 1/2 hour break between jobs. so I look for someway to take time. thought I would try this trail it's peaceful if you like solitude it's excellent. the highlight of this trail I think is the boulder outcrop.

Great trail, there is multiple loops to choose from. Cool switchbacks up and down the mountain. Trails are easily marked and exciting. Enter from Alpine street, there will be a small park on the left to park at.

First time on this trail. The trail as it appears on the map does include the Red, then Light Blue, and a little bit of Orange, then back to Red trails. A bit confusing if you have never been on this trail system.
I would advise wearing good sturdy shoes like hiking boots because of the mixed terrains of rocks, roots, and boulders.
This was a fun trail system with many options so your hike could be as long or short, easy or hard as you want to make it.
