Cairns is an adventure sports enthusiast's paradise: every second shop is a tourist information centre with signs blaring "dive dive" or "tandem skydiving". Its location close to the ocean, the mountains and the rainforest gives travellers lots of choices of activities.
Standby rates are ubiquitous: many of the more expensive activities, including scuba diving and skydiving, are up to $150 cheaper if you are prepared to go on standby for a cancellation.
Many coach tours depart Cairns daily, with a couple of hundred to choose from. There are rainforest tours to Mossman Gorge, the Daintree River, Cape Tribulation, and the Cairns Highlands (Atherton Tablelands), specialised 4WD tours, city sights tours, tours to wildlife parks, outback tours, and much, much more.
A number of Cairns operators run day and liveaboard scuba diving trips from Cairns. For seeing the Great Barrier Reef, the smaller dive boats provide the best experience, both for diving and for snorkeling. The larger operations have more amenities - better food, larger and faster boats, more activities, but sometimes provide a poorer underwater experience, as the underwater areas that the larger boats visit are heavily overused, and somewhat barren of coral and fishes. Your mileage may vary.
Always wanted to try ballooning? The Cairns region has some of the best weather for ballooning in the World and so trips go year round and are rarely cancelled. It's also one of the cheapest places to go flying, anywhere. The trips go inland to the Atherton Tablelands and take off at first light at Mareeba, finishing around 10AM and can connect directly to a Great Barrier Reef tour or drop you in Kuranda.
Rafting in North Queensland has the advantage of departures all year round, tropical water temperatures and ease of access to compliment breath-taking scenery and rapids. The region's white water rafting adventures are suitable for all levels of fitness and enthusiasm. Ride through our planet's oldest continuously growing tropical rainforests on rivers that still run totally wild.
