Reefs we visit

Dive the most amazing reefs in the Cairns area


Coral Sea Dreaming has access to over 25 moorings on 9 different reef systems including some of the most famous dive sites around Cairns.

Three Sisters, The Whale, 5 Ways, Michaelmas Cay are just some of the many sites we visit.

Where will we go?

We choose the most comfortable reef locations based on current weather conditions, so reef locations vary from trip to trip.

In strong winds, the boat usually travels north, visiting a selection of reefs which may include Hastings, Michaelmas and Breaking patches. In lighter winds, we visit the southern reefs - Milln, Flynn or Thetford.

Will the location be suitable for me?

Our locations include shallower and deeper areas and are suitable for both divers of various skill levels and snorkelers.

What about visibility?

Visiting only the mid- and outer- reef systems means we experience up to 40m visibility at times!

Of course, visibility varies throughout the year and different sites, but is generally very good at all locations we visit.

What will I see?

The Reef is home to a diverse range of coral and fish species. You can expect to see everything from the miniature nudibranchs and reef fish to sea turtles, reef sharks, pelagic fish and even the occasional Manta ray!

Don't forget to keep an eye out for playful dolphins and breaching whales on the way to the reef as well!
