I had intended to do this hike a little differently but ran into a snag and had to reroute so you might want to avoid this section of trail.  The red-blazed Trexler Border Trail crosses over Jordan Creek below kiosks #4 and #3 on the left side of the map.  Although the trail continues on the other side, it is not possible to ford the creek.  The water looked to be at least waist deep, if not deeper in the middle. 


  1. Hey thanks for this great resource! I just stumbled upon your blog when I was looking to direct a friend over to Pawlings Farm -- a place that I've been visiting with my 5 year old GSD since she was 4 months old. I am going ot try this Trexler Hike soon.

  2. Heidi - You must know all of the unofficial trails at Pawlings Farm. I hiked them a couple of times about 10 years ago with a local woman who knew those trails but I could't remember where they were when I was there last year. You'll like Trexler - it's very scenic.


  3. Hey, When I did the Trexler Border Trail on 6/24/2012 at around mile 4.0 - 4.5 there is a paper posted on one of the wooden posts that says to turn back and take a detour because the bridge is not ready yet.... Does anyone know if the bridge is ready I really wanted to finish the red trexler border trail.

    1. Trexler Nature Preserve should be able to tell you. Their number is 610-871-1444.


    2. Medieval ... just finished the Trexler Border Trail earlier today and the bridge isn't ready. Actually it hasn't even been started. Luckily the water was only a few inches deep so I took my boots off and waded across. It beat retracing my steps back up the steep hill.


    3. As of Sunday 4/21/2013 there still is no bridge

    4. Still no bridge in July 2013.

    5. No bridge on 8/31/13, no construction either. It is not bad to walk across though.

    6. We did the Border trail yesterday (9th Aug 2014). No bridge nor any signs that one might be ever constructed. The water level was low enough to wade through. Just a case of taking boots and socks off to continue the trail on the other side.

  4. Thanks for posting this. I am planning a day trip to the area. This was very helpful.

    1. Thank you! I am sure know you will enjoy it, it's a very neat place!


  5. As of late 2015 there is a bridge over the Jordan Creek where your orange circle is indicated; this means one can now do the complete Trexler Border Trail - roughly 8.5 miles in total.

  6. Bridge over Jordan Creek was erected in 2016. You can keep those boots and socks on now!

  7. a wonderful resource for hiking this area. great pictures as always!
