The main activities in Port Douglas involve both land and water in the form of rainforests and the Great Barrier Reef. They are both within shouting distance of Port Douglas, with the Daintree Rainforest just inland and fringe reefs extending from the shoreline.
As would be expected, there is some fantastic scuba diving and snorkeling to be had near the shore and within a couple of hours' boat ride, along with unbeatable bushwalking and hiking. You can also kayak the Daintree River or kitesurf Four Mile Beach and even play golf at the Mirage Country Club.
Great Barrier Reef tours
The Great Barrier Reef proper is only a few miles offshore from Port Douglas and tours of the likes of Batt and Tongue reefs are popular. In addition, there are many fringe (inland) reefs to check out, with Morey Reef literally steps from town to the north and Alexandra Reef just off of Four Mile Beach.
Snorkeling and diving
As gateway to the Great Barrier Reef, Port Douglas has good options for diving and snorkeling, with tours regularly leaving Marina Mirage. You can snorkel over reefs and see all sorts of exotic fish and even whales, as well as take to the Mossman River and snorkel there.
Mirage Country Club
Located just south of town, the Mirage Country Club is perfect for the active, and especially for golfers. There is an 18-hole championship golf course here, along with an aquatic driving range, several tennis courts, a swimming pool, saunas and a Jacuzzi.
