Ponquogue Bridge

#1 - Ponquogue Bridge

New York, USA East

beginner

This dive needs to be timed so that you make it at slack tide only due to the strong current. High slack tide will give you the best visibility. There are lobster and lots of other marine life. Late in the season I have even found tropical fish there brought up by the gulf stream. Take Sunrise Highway to Exit 65 South. Make a left onto Montauk Highway, then a right turn onto Ponquogue Avenue. Take this to the end and make a left on Shinnecock Avenue. Turn right on Foster Avenue, when you see the new bridge you can turn left just before it for the northern side of the bridge. For the southern side drive over the new bridge to the end of the road and make a U-turn onto the service road. Ponquogue Bridge is also known as Old Ponquogue Bridge.

Lloyd Neck

USA, New York, Long Island

You can reach this site through Caumsett State Park but you will need to set this up in advance as you need a permit to drive to this site. Shore access is a short walk from the parking lot. Depth changes the further you go off shore and the greater the chance of boat traffic. Area is good for lobster and other local marine life. From either the LIE or Northern State take the Round Swamp Rd exit north to the end. Turn right on Rt 25, left on Oakwood Rd, left on High St and right on Woodbury Rd. Woodbury Rd turns into West Neck Rd and later into Lloyd Harbor Rd. Lloyd Neck is also known as Caumsett State Park.
Smithtown Bay Artificial Reef

Reef is made up of a barge and tires. Lots of marine life including lobster. Site is about a mile offshore and can only be reached by boat. The site is sometimes marked by a buoy but due to a fair amount of boat traffic that is not usually the case. Without a GPS you will have a very hard time finding this site.
Shinnecock Canal Jetty

#6 - Shinnecock Canal Jetty

USA, New York, Long Island

beginner

This is a long jetty with very little current except at the end of the jetty where the current can be strong at times and wakes from boat traffic can make it a tough place to swim. You can not dive on the inside of the jetty due to the current and boat traffic. There is lots of marine life with a few lobster. At low tide you can snorkel this site end to end. Sunrise Hwy. east, after you cross over the canal take the first exit, North Shore Rd. At the end of the exit ramp go straight onto Canal Rd. north, right on Old North Hwy. and make your first left into Meschutt Park. Shinnecock Canal Jetty is also known as Meschutt Park Jetty.
Duck Pond Pt.

#7 - Duck Pond Pt.

USA, New York, Long Island

This site has a sand and gravel bottom extending out to about 150 yards, after that it is mud bottom. There are large rocks and boulders close in making it good for lobster and spear fishing. There are large rocks to the west for at least a half a mile. The point itself is 1/8 of a mile east of the access point. I would recommend starting at the point towards the end of an incoming tide and drift dive the whole way down and either walk or swim back depending on the current. LIE exit 71 north on Edwards Ave to Sound Ave east to Depot Ln north. Depot Ln turns into Duck Pond Rd, take it to the end.
Gwendolyn Steers Wreck

The Gwendolyn Steers is a tugboat that sunk in about 55ft of water. The wreck sits upright and comes to within about 25ft of the surface. It is 96ft long with a 20ft beam. Visibility is usually poor, there is a fair amount of boat traffic and nets have been present in the past. Access is by boat only. Gwendolyn Steers Wreck is also known as Gwendolyn Steers.
Sag Harbor Jetties

#9 - Sag Harbor Jetties

USA, New York, Long Island

beginner

The site is made up of two jetties that are the barriers for the harbor. The first starts at the beach and goes out about 350 yards. There is a 30 yard gap between the first and second jetty, the second jetty is about 600 yards long. Other then the jetties the harbor itself can be interesting dating back to the 1600s but there is a lot of boat traffic to deal with once you get away from the jetties. Montauk Hwy Rt 27 east to Bridgehampton. Take Bridgehampton / Sag Harbor Turnpike north, turns into Main St and ends at the harbor. Though the jetty starts on the beach there is no way to get to it that I know of so this needs to be a boat dive. I have made this dive from a sit-on-top kayak. Sag Harbor Jetties is also known as Sag Harbor.
Greenport Jetty

#10 - Greenport Jetty

USA, New York, Long Island

This is a great place for a large assortment of marine life including lobster. The area is sheltered from wind in most directions but boat wakes can be a problem on weekends. The current can be a problem at the tip of the jetty during peak tide change. The site is well worth the drive and walk. LIE to exit 71 north on Edwards Ave, right on Sound Ave [long drive] turn right on Manhanset Ave to the end. Klipp Park Beach is at the end of Manhanset Ave, it is a local beach but you can buy a day pass. You can walk the 1/3 of a mile to the jetty or put a boat in at the Klipp park ramp.
