Link Trail Rte 154 Detour Update

The contractor is beginning to pave Rte 154, between entrance to World's End State Park and World's End Road, thus ending the Link Trail Detour.  The Link trail is now open at its original Rte 154 crossing and now follows the itinerary in the LT Guide and any other Maps.  Thanks for your patience and cooperation during this critical construction.

20th Edition of Loyalsock Trail Guide & Maps

The most recent Edition of our LT Guide and Maps is the 20th Edition.  We recommend using this most recent Edition, if you are doing any longer-term hikes, especially thru hikes.  Although the geographic and physical itinerary of the LT has not changed significantly, there have been some residually minor corrections to mileage and altitude, and the beginning Table of Contents has gone through some reorganization.  The biggest change is that the Guide is now spiral-bound, with a plastic flip spiral at the top.  This makes it much easier to more permanently move through pages of the Guide, as you navigate across the Trail.  To order the new Guide from its various sales sources, please visit or Order Guides webpage: Order 20th Edition

Gas Well and Pipeline Activity on Allegheny Front

PGE gas is currently in the process of creating space for a gas pipeline and road on the Bryan Hay Trail (Road) which shares space with the Loyalsock Trail on mile 3.38 - 3.60.  The LT in that area is currently a muddy mess and the trees that formerly held our LT markers are gone.  The Alpine Club has placed new LT markers on both sides of the trail to aid hikers continuing on the Trail.  When we have a better idea of what they are doing, we will put in a permanent reroute that will keep us away from the new gas road.

If you plan to hike in this area, please follow the existing route (in spite of the mud).

You may encounter an open 3 foot deep ditch.

Remember, trucks and equipment always have the right of way!

Be safe and enjoy your hike.
