H2: The snorkel route: Little Salmon Bay to The Basin

H3: Segment 1 — Little Salmon Bay to the reef edge Starting in a sheltered, sandy inlet, you’ll soon reach the edge of a shallow reef system. This is where the water clarity shines and the marine life begins to show itself in earnest.

• What you’ll see: Small schoolfish, damselfish, wrasse, and gobies patrol the reef folds. You might spot a friendly cuttlefish gliding by or a shy moray peeking from a crevice.
• How to snorkel it: Keep a steady pace and use slow breaths to conserve air. Look for patches of bright coral, sea urchins, and protective reef flats where juvenile fish gather.
• Tips: If you’re practicing snorkeling techniques, this section is ideal for refining buoyancy and ocular focus on small, fast-moving fish rather than larger targets.

H3: Segment 2 — Shallow reefs along the coastline As you transition along the coastline, you’ll encounter more pronounced reef structures and wider tidal eddies to navigate. The water often becomes a touch deeper here, offering a broader view of the reef fabric.

• What you’ll see: Parrotfish nibbling on coral, angelfish hovering above corals, and occasional stingrays gliding over sandy bottoms. You may also encounter crustaceans and anemones tucked into rock crevices.
• How to snorkel it: Use a relaxed kick to maintain control around the reef edges. Keep an eye on potential pockets of current near headlands and stay alert for rolling swells from the open sea.
• Tips: If you see a sign indicating protected zones, pause and admire from a respectful distance. Rottnest’s reefs are living laboratories, and maintaining distance helps preserve them.

H3: Segment 3 — The Basin approach and final currents The Basin is widely celebrated for its shallow, glassy water and bright white sand bottom. This segment is typically calmer and offers a reward-filled conclusion to your snorkel.

• What you’ll see: A wide array of reef fish in schools, sea stars on the sandy bottom, and perhaps rays cruising near the sand or under a couple of overhanging rocks. The Basin often hosts big shoals that create a dynamic underwater landscape.
• How to snorkel it: Slow, deliberate strokes keep you in tune with the water and avoid startling marine life. When you approach The Basin, you’ll notice the water clarity improving, making it a prime moment for photos.
• Tips: The Basin’s shallow, sheltered water is ideal for a relaxed float or a quick break to appreciate the scenery. If you brought a camera, you’ll be spoiled for light and color here.
