Erl King

Natural Attraction
Barrell shaped concrete object resting in the bones of an underwater shipwreck

The outline of an iron-hulled steamer rests 18 feet below the surface of Long Reef—a 306-foot vessel named Erl King, built in Glasgow in 1865. The ship ran aground here in December 1891 while en route to New Orleans from Swansea, England, and was abandoned after salvage attempts. Today, visitors can see the hull's silhouette and the ship's cargo: concrete casts that once were wooden barrels filled with dry concrete mix, their wooden forms long consumed by shipworms, leaving only stone impressions behind.

  • Check boating forecasts and tidal conditions before launching.
  • Marine life is abundant; maintain 25-yard distance from dolphins and sea turtles.
Insider Tips
  • The concrete cargo casts are the remnants of wooden barrels filled with dry concrete mix—shipworms hollowed the wood centuries ago.
  • Best visibility occurs on calm, sunny days after winter cold fronts.
  • Bring polarized sunglasses and a fish-and-wildlife identification guide.
  • Coordinate your visit with tidal windows for easier navigation.
  • Snorkel photos are clearest in morning light when shadows are minimal.

Location

Frequently asked questions

Can I see the wreck from my boat without snorkeling?

Yes. The hull outline is visible in 18 feet of water from directly above in calm conditions. Snorkeling or diving reveals more detail and photographable cargo remains, but surface viewing is possible.

What happened to the Erl King, and when?

The ship ran aground on Long Reef on December 16, 1891, while en route to New Orleans from Swansea, England. It was abandoned after salvage attempts. Iron hull plates were later used as scrap metal during World War II.

Is it safe to snorkel around the wreck?

Yes, when following standard boating and marine safety protocols. Maintain 25-yard distance from marine life (dolphins, sea turtles). Wear a life jacket on the boat and check weather and visibility before entering the water.

Can I take souvenirs or artifacts from the wreck?

No. The shipwreck is a protected historical site. All artifacts and structural remains are protected by National Park Service regulations.

When is the best time for visibility?

December through April offers calmest seas and clearest water. Avoid the site after recent storms when sediment clouds the water. Early morning departures yield the calmest conditions.
