Why go
The **Great Barrier Reef** stretches for around two thousand three hundred kilometres along the Queensland coast and is the largest coral reef system in the world. From Cairns and Port Douglas you can reach healthy outer reef sites in a morning, snorkel among turtles, giant clams and reef fish, or learn to dive. The reef has faced coral bleaching events in recent years, but many sites remain beautiful, and operators move between reefs to find the best conditions.
Choosing a reef trip
There are three main styles. **Outer reef** trips on large catamarans or pontoons visit the edge of the reef with the clearest water, and suit families and nervous swimmers because of their facilities. **Smaller boats** carry fewer people to several sites and suit keen snorkellers and divers. **Island trips** to **Green Island** or **Fitzroy Island** are shorter and cheaper, with beaches and reef close to shore. Look for operators certified by the Great Barrier Reef Marine Park Authority's high standard tourism programme, which also supports reef conservation.
The Daintree and Cape Tribulation
North of Port Douglas, the **Daintree River** ferry leads into the rainforest. Visit the **Mossman Gorge** with a Ngadiku Dreamtime walk led by the local Kuku Yalanji people, take a river cruise to spot crocodiles, and continue to **Cape Tribulation**, where the rainforest meets the reef. Allow a full day, or stay overnight in a rainforest lodge.
Port Douglas
An hour north of Cairns, **Port Douglas** is a smaller, more upmarket resort town with the long **Four Mile Beach**, a Sunday market and good restaurants on Macrossan Street. It is closer to the Daintree and the Low Isles, and many reef boats depart from its marina.
Kuranda and the Tablelands
The **Kuranda Scenic Railway** climbs through rainforest and past waterfalls to the village of **Kuranda**, and you can return on the **Skyrail Rainforest Cableway** above the treetops. Further inland, the **Atherton Tablelands** have crater lakes, waterfalls and platypus spotting in quiet creeks.
Cairns itself
Cairns has no swimming beach in the centre, but the free **Esplanade Lagoon** is a lovely spot to swim and relax. Evening markets, casual seafood and the waterfront boardwalk give the town a holiday feel. The northern beaches, such as **Palm Cove** and **Trinity Beach**, are good for a quieter stay.
Stinger and crocodile safety
From about November to May, dangerous jellyfish known as marine stingers, including box jellyfish and Irukandji, are present in coastal waters. Swim only in stinger nets at patrolled beaches and wear the stinger suits reef operators provide. Saltwater crocodiles live in rivers, estuaries and some beaches in the region: obey warning signs and never swim where they are posted.
When to go
The dry season from **May to October** has warm days, low humidity and calm seas. The wet season from November to April is hot and humid with heavy rain and the chance of cyclones, though the reef can still be visited on many days, and the rainforest is at its lushest.
Where to stay
Stay on or near the **Cairns Esplanade** for easy access to reef boats, in **Palm Cove** for a beach resort feel, or in **Port Douglas** for a relaxed town close to the Daintree.
Questions about Cairns and the Great Barrier Reef
Is the Great Barrier Reef still worth visiting?
Yes. Bleaching has affected parts of the reef, but many sites are still colourful and full of life, and operators choose the best sites each day. Visiting with a certified operator also supports reef management.
Do I need to be a strong swimmer to snorkel the reef?
No. Pontoons and larger boats have flotation devices, lifeguards, guided snorkel tours and semi-submersibles or glass-bottom boats for non-swimmers.
Cairns or Port Douglas: where should I stay?
Cairns has more choice, nightlife and budget options. Port Douglas is quieter and closer to the Daintree. Both have daily reef trips.
When is stinger season?
Roughly November to May, though stingers can occur outside these months. Use stinger nets at beaches and wear the stinger suits provided on reef trips.
