1,000 Islands


Dive the Canadian Caribbean
Join us on our East Coast Dive Tour trip to the 1,000 Islands to dive the incredible wrecks of the St. Lawrence River. Visibility in these 70°+ waters can reach 60 feet this time of year, and the currents cause the lake to have no thermoclines – even to depths of 130ft – earning the name Canadian Caribbean. This trip is perfectly suited for all levels of divers.

The 1,000 Islands are as beautiful underwater as they are above water. The irregular bottom contour provides many shallow shoals that surprised unsuspecting ships, leaving them scattered about the lake bottom, but remain in excellent condition due to the freshwater. From paddlewheel steamers of the 1800’s to contemporary freighters, this river has them all awaiting us.

Sailing on the best of the river …
We’ll be diving off some of the most spacious boats available featuring enclosed cabins, wide, easy to board ladders, an indoor head and an upper deck for relaxing between dives on Saturday and Sunday.


During this trip, you’ll have the opportunity of diving some of the best and most unique wrecks in the area. These wreck sites include:

On Friday afternoon upon arrival, we will be diving on the wreck of the Rothesay, an old paddlewheel steamer off Prescott, Ontario that lies in only 28 feet of water.
  See more spectacular photos of the Rothesay.

Robert A. Gaskin
The Gaskin was a double masted iron rigged wood barge built in Kingston Ontario in 1863. She is 113' x 26' and sits on a firm bottom with the bow at about 50' and the stern at 65'-70'. The Gaskin's upper deck is quite open allowing ample ambient light for easy penetration throughout the wreck.  A great wreck for new wreck divers!
  See more spectacular photos of the Gaskin.

Double tanks, drysuits and DPV's are not required to dive these wrecks.

Lillie Parsons
The Lillie Parsons is a unique center-board schooner that's 131 feet long.  On August 5th, 1877, while carrying a cargo of coal, she hit a rock and took on water as her cargo shifted during a squall. She sank next to Sparrow Island in only 40-60 feet of water.  A great dive with even greater drift!

   Double tanks, drysuits and DPV's are not required to dive these wrecks.

The Kingshorn is a largely intact wooden barge sitting upright in 90' of water. Divers love this wreck for it's great photo opportunities below deck and around the ships wheel.
  See more spectacular photos of the Kingshorn here.

The area's most popular wreck, the Keystorm was a 256' steel laker built in 1908 that went down in October, 1912 after it struck Scow Island's outer shoal. From swimming through it’s immense cargo holds, to the spectacular photo opportunities by the wheelhouse and prop, this wreck has something for everyone. She sits on its starboard side in 20' to 120' and is truly an unforgettable wreck.

 This 4-legged ship was used to dynamite sections of the St. Lawrence Seaway to make it deeper and safer for travel. She awaits us, upside-down in 80 feet of water outside the shipping channel.
  See more spectacular photos of the America and here.

Our Monday, our Advanced dives will be on the wrecks of the Muscallonge and Daryaw:

The "Muskie" was the largest tug on the river at her time. Shortly after midnight on August 15th, 1936, a fire was discovered in her boiler room and quickly spread. As the flames continued to soar she had burned to the water line. At 5:30 the fire had reached her fuel tanks and exploded sending flames 80 feet into the air. The shock practically obliterated her hull and she broke in two as the bow settled into 95 feet of water in a medium to good current. She has become one of the most popular sites for the local fish population, the boiler, winches, the engine and various other ships parts.
  See more spectacular photos of the Muscallonge here.

Henry C. Daryaw
The Henry C. Daryaw is a 219' x 35' steel freighter built in France in 1919. While crossing a shoal around Crossover Isl. on Nov. 21, 1941 she tore a large gash in her starboard side where sank intact but upside-down in 90 feet of water.  Excellent wreck with very interesting areas to explore.
   See more spectacular photos of the Henry C. Daryaw.

And during our surface intervals on Saturday and Monday, we’ll be once again BBQ-ing Dogs and Burgers for your dining pleasure.
