Great Barrier Reef
No trip to Cairns is complete without experiencing the Great Barrier Reef. It's one of the world's most spectacular natural wonders, offering incredible snorkeling, diving, and glass-bottom boat tours. You can explore vibrant coral gardens and encounter diverse marine life. I think it's truly breathtaking. Many operators offer day trips from Cairns, making it easily accessible.
