I've been looking for a detailed map of the Liberty Water Gap Trail and can't seem to find one anywhere. Their website, LibertyWaterGap.org, doesn't exist anymore, and Google searches only bring me to NJ.com articles from 2011. Hopefully you are able to help me or point me in the right direction for information.
Here are a few suggestions for that area. If any readers know of other sources, please share in a comment below.
I like holding a map in my hands on a trail and the NY NJ Trail Conference offers NYNJTC maps and the Water Gap is included in their Kittatinny Trails map.
You can also find a number of maps of that area from Amazon.
The Delaware Water Gap National Recreation Area (National Park Service New Jersey/Pennsylvania) offers a free pdf format set of trail maps in the area.
There are a number of maps at npmaps.com/delaware-water-gap/
Personally, I wouldn't rely on Google Maps for a hike, but their maps and the Google Earth view does give a pretty good sense of the area.
