Port Douglas offers world-class snorkeling at two main locations: the Low Isles and the outer Great Barrier Reef. The calm, protected waters make this an ideal spot for both beginners and experienced snorkelers.
The best tours combine small group sizes (maximum 12-15 people) with expert guidance and quality equipment. Our favorite options include the half-day Low Isles trips, which provide a gentle introduction to reef snorkeling, and the full-day outer reef adventures for those seeking more diverse marine life.
I’m particularly fond of the morning Low Isles tours – they avoid the afternoon winds and offer better visibility for spotting sea turtles, rays, and countless tropical fish. For serious snorkelers, the full-day Agincourt Reef excursions are worth the extra time and money, offering pristine coral gardens and larger marine life.
