"Hello, for any future walks on the D&R Canal towpath starting from Landing Lane, here's a more convenient place to park for those driving there http://goo.gl/maps/wtPnXiKsejx
Cheers, Karen Lee"
I'll be sending out directions latter in the week.
The turn around point is the Palisades Police Station (restrooms and water) at 1 Alpine Aproach Rd Alpine, NJ
It is closer to 9 miles one way when you add in the walk across the bridge.
