Cairns tours: The Great Barrier Reef

If you are in Cairns you'll surely have the traditional Cairns tours - at Cape Tribulations and at the Great Barrier Reef. The trip to Cape Tribulations is made look like a safari but in fact there is no danger, as the road is sealed.
The Cairns Great Barrier Reef and islands tour includes also diving and snorkelling. You can go with Compass, the cheapest offer (A$60) and good service or with Noah's Ark Cruises if you like more snorkelling.
