Northern Erojacks

In the 1960s, the authorities created a 250-yards-long artificial coral reef 600 yards off Fort Lauderdale, aiming to help combat the erosion of the beaches. The reef was made of concrete tripods, and not very aesthetic, but was quickly colonized by underwater fauna. The spot itself is not really worth a visit, but you might explore it during an excursion to the Twin Ledges reef.
How to get there?

Although it is not far from the coast (facing Bahia Mar), you need to take a boat to access the spot safely. A few diving centers in Fort Lauderdale organize snorkeling excursions to the spot at relatively reasonable prices ($30-40 for about 2 hours 30 minutes), and also including a stop at Twin Ledges. From Miami Beach, it takes about an hour by car (direction Fort Lauderdale Beach). By public transport, go to Aventura Mall (lines S, C or 120), then take the line 1 BCT, and finally line 40 at the fork towards the beach (ask the driver to let you off). It takes about two hours and costs between $1.75 and $2.25 per section.

Water entrance

You enter the water from the boat. Follow your tour guide’s instructions.

Aerial view


The artificial reef (about 16 feet wide) extends for about 250 yards at right angles to the coast. On either side of the reef, you will come across sandy areas of little interest.

Swim above the tripods (↕10-20ft/3-5m). Although the reef has been colonized by a few sea fans and a little soft coral, it still looks a little artificial. But a wide variety of species have found a home there: many yellowtail snappers, jacks and, above all, French angelfish are to be seen swimming around the reef. Explore the crevices to look for lobsters, which are relatively common. It is also possible, although not common, to come across sea turtles near the reef.

Because of its relative depth, exploring the reef is not easy. Visibility varies and sea conditions can be bad, depending on the wind and waves. Follow your tour guide’s instructions, and if you are visiting on your own boat, check out the safety conditions before getting into the water.

Restaurants & accommodation

Excursions don’t generally include meals, but sometimes drinks. At the Fort Lauderdale marina (the starting point for the excursions) you can buy a snack and some water.
