Need help finding a venue for a scout backpacking trip, for a Delaware based troop

Not my area but check out this website for ideas. http://www.midatlantichikes.com

Hope this helps.

Appalachian Trail

Newark to Duncannon, PA = under 100 miles
Newark to Palmerton, PA = about 115 miles

Between Duncannon and Palmerton is 110 miles of AT. There are a fair number of road crossings in this section for shorter trips.

Check out "Map of long trails" at fivemillionsteps.com

I was going to suggest a portion of the AT in that region as well. It's 89 miles to where the AT crosses RT 501 north of Bethel, PA. I could possibly help with shuttling cars if you needed some help because I'm only about 45 minutes from there. A hike from Rte. 501 to Rte. 61 (near Cabela's) is about 24 miles.

I've only hiked a little bit around Rte. 501 so I can't tell you about campsites, but you should be able to find some info about those.

Due to heavy use, group size on the AT is limited to 25 on day hikes, 10 on overnights.

Thanks from a maintainer for honoring this LNT restriction.

I do agree on the group size suggestion. I would tend to split the group mentioned in two with groups starting at each end. This way not shuttles are needed, just an exchange of vehicle keys at the crossing point.

That's a good idea Ed…I like the way you think!
