Two Choices here. At a Street entry one block inland on the Belmar side, there are narrow steps going down to the water. All diving is east to the ocean. The other choice is park on the Avon side and entry is a giant stride off the bridge base; exit is climb back over the rocks, but the plus is showers next to the boardwalk. Both sides, all diving from Memorial Day to Labor Day is dusk to dawn, a flag is a must, watch out for fishing lines and stay out of the channel. Best diving is high slack tide when vis is best, and lately that has been 15-20'. The usual mix of Jersey marine life is among the rocks. Once you get comfortable with this site and the ocean is flat you can ride the tide out from the Avon side, the north running current will take you up the beach and you walk back up the beach to the showers.
