Sorry, I should have put this in my last post: Edwin B. Forsythe National Wildlife Refuge is located at 800 Great Creek Rd., Oceanville, NJ telephone 609-652-1665, and web site
There is the tram tour (which we took) that givew you a good idea of the scope and history of the place as well as what birds are there to be seen. It is donation only and run by volunteers but you should call to reserve a seat, the tram holds about 10 people.
There are hiking trails from one mile (the songbird trail) to five miles, maps available at the ranger/visitor building. There are also sandy roads for driving through the marsh meadows and the birders are generally friendly and helpful if you ask them what they are viewing. So, if you don't want to do a lot of walking, try the tram. I believe it runs all year, but phone ahead to make sure and make your reservation!
