Whoo doggie, are you in for a treat.
Start with Atsion Lake, putin at N 39.44.787 W 74.45.853. Paddling through the ponds is a truly amazing experience.
Another great spot is Batsto Lake, if you have a GPS, the coordinates for the putins are near 39.660 W 074° 39.131. These coords are approximate so have a look a map.
Also nearby, you can paddle downstream through "The Forks" where the Batsto and Mullica Rivers meet. It's tidal, so pay attention to the tables and go at high tide. Putin near Pleasant Mills Rd at the Batsto River (you can drive downstream a little bit, as you pass Batsto Village heading East, there is a sandy road off to the right with a sign, drive in a bit and you can putin sorta near these coordinates:
N 39° 37.762 W 074° 38.605
Again, these are approximate coords. There's a bend in the river with a beach where you can park and get in the water.
There are so many places, but these three are good places to get your feet wet. Have fun and happy paddling!
