Great Barrier Reef snorkeling & diving: Two reef sitesA full-day snorkeling and diving trip from Cairns to the Great Barrier Reef, visiting two sites on the Norman, Saxon, or Hastings reefs about 90 minutes offshore. You choose your level—snorkel, try an introductory dive with instruction, or do certified dives—and the boat handles all equipment, lunch, showers and tea. The operator reserves the right to prevent participation if a health questionnaire or medical assessment raises safety concerns.Is it for me?Book snorkeling if you want the reef without learning to dive; choose the introductory dive to try breathing underwater with instruction and no certification required; pick certified dives if you have your card and want to go deeper at multiple sites.
Port Douglas Reef Tour: Snorkel, dive & submarine in one dayYou board a catamaran in Port Douglas, spend ninety minutes crossing to Agincourt Reef, then get 3.5 hours to snorkel, watch the submarine tour, or try an introductory dive — all with gear, lunch, and a marine biologist on hand. No experience needed, and you can change your date for free if your plans shift.Is it for me?Right for first-time reef visitors or non-swimmers who want to see the Great Barrier Reef without committing to diving or snorkeling alone. The 3.5 hours at the reef gives you time to try one activity properly instead of rushing, and the pontoon setup means you're never far from help or a dry place to rest.
Port Douglas: Great Barrier Reef Snorkel & Dive CruiseYou get picked up from your Port Douglas hotel, spend five hours snorkeling or diving across three Agincourt Reef sites with a marine naturalist guide, eat a tropical lunch on the boat, and return in the afternoon.

Plan for a full day out of Port Douglas, which is what gives you three reef sites and five hours in the water instead of a rushed half-day trip.

Great Barrier Reef: Overnight Sail, Dive & Snorkel Tour CairnsYou’ll sail out from Cairns with just 12 people and wake up anchored right on the Great Barrier Reef.
