That depends on what part of the river you are talking about. If it is the Egg Harbor, There's a few different places that will put you at various parts of the river, as far up as the Mays Landing Bulkhead.
i know that you guys don't want to give away spots. thats understandable. i can figure out how to get at the mouth of the river. i'm looking for launch spots upstream. I'll do it on my own, i can sense that its a bit tight lipped on this subject. i can understand.
I'd go in from McNamara at Tuckahoe. Tuckahoe River goes right down to Beeseley's Point. It's free and a nice ride and there's fish. On the other side you have the bulkhead at Mays Landing, Shady River Marina, Thompson's and if you ask politely many homeowners would allow you to launch.
You can also launch from Atlantic County Park in Estell Manor onto the South River at either the Main Park (floating dock) or the ramp at the group camping area (Artesian Well Road). Either is about a 10-15 minute paddle to the EHR.
