    Cayman Aggressor IV will take you on 7-day itineraries which include the highlights of Cayman diving featuring some great topography.

    Itinerary map with diving summary  .... open
      During the week, weather permitting, you will dive the best of all three islands including the Russian Destroyer (Kittiwake) in Cayman Brac, Bloody Bay Wall in Little Cayman, and Stingray City, Northwall, Southwall in Grand Cayman.

    Topography reigns supreme here with walls, passages, pinnacles and swim throughs … all sporting colorful corals and sponges. Plenty of reef fish, turtles, eels & rays … a few sharks and some nice critter action. Continue reading for a few of the highlights.

    3 Fathom Wall (Mixing Bowl) … here, the “shear” wall, meets the “gentle slope”. This site offers more fish than any site in Little Cayman. Schools of Bermuda chub, 3-spotted goatfish, snappers and various grouper species can be seen … as well yellowhead jawfish. Watch for turtles, spotted eagle rays and occasional reef or nurse sharks.

    Bonnie's Arch …. this site has a beautiful arch that provides photo ops. Look for seahorses, angelfish and crabs.

    Bullwinkle East ... this site gets its name from the large elk horn coral that forms the top of this shallow reef.

    Doc Poulson (wreck) … in an open sandy area, with nearby coral reef, the small vessel was sunk purposely to make a dive site. Good growth on the wreck provides a home to many juvenile fish including the pygmy file fish.

    Great Wall … a shear drop, this portion of Bloody Bay Wall is full of beautiful vegetation – gorgonians, hard & soft corals, rope sponges. Turtles are often seen munching on a sponge or just swimming by. Look for juvenile spotted drum fish and juvenile smooth trunkfish here.

    The Meadows … Jackson’s Wall is a highlight with swim-throughs onto the lovely wall. Watch for Caribbean reef sharks.

    Lea Lea’s Lookout … A narrow cut leads to the wall where you can look for crabs and lobster hiding out. Divers love the “Great Room” (entrance around 80 feet) at this site where they exit at around 30 feet. Night dives here are great with reds, oranges, greens & purples shining in the low light.

    Kittiwake & Keith Tibbetts … The Kittiwake, sunk in 2011 as an artificial reef, lies in 40-90 feet of water & provides a great backdrop for photos & videos. Penetration is allowed for the avid wreck diver & there are countless areas inside to explore. The Tibbetts is always a popular dive offering charming photo ops.

    Ore Verde (wreck) … this wreck lies in pieces against a section of coral reef and provides a home to many fish, both during the day and at night (midnight blue parrotfish). Hordes of chub, jacks, and snapper are spotted during the day.

    Randy’s Gazebo … wonderful swim-throughs & some of the largest barrel sponges in the Cayman Islands. A great “photo op” at the “gazebo … and a narrow passage that begins at 80 feet & “burps” you out at 30 feet are popular moments.

    Stingray City … probably the Caribbean’s most popular (or only) 12-foot dive, Stingray City is home to many Southern Stingrays who seem to love performing for divers

    Tarpon Alley … large sand passage slice through coral fingers, leading out onto the North Wall. Between two of these fingers, you can find tarpon displaying their buoyancy. Barracuda sometimes pose as “imposters”, lurking around, looking for a meal. On the wall, the beautiful spotted eagle ray is often cited as well as an occasional reef shark. If you are really lucky, you might spot a hammerhead.

    Teacher’s Caverns (Bats Cave Reef) … elkhorn and staghorn corals are found in the shallows & there’s a beautiful wall & pinnacles.

Guests arriving on Saturday from 11:30 am – 6 pm are greeted at the airport by a Cayman tour guide who will be wearing an Aggressor Adventures hat and shirt and will have guests names on a sign.  Airport transfers are an extra cost for these departures.

The yacht will depart the dock early Sunday morning.

    The Cayman Aggressor IV normally docks at the George Town Tourist Dock, however, during the winter months, she occasionally docks at a local marina.   We will give you all necessary details before your departure.  On your return from the week of diving, you'll arrive at the George Town Government dock Friday afternoon after lunch.
