Cucumber Alley combines a wall and reef structure across a depth range of 5 to 35 metres, putting both shallow reef terrain and deep diving territory within reach on a single dive. Visibility runs 10 to 30 metres depending on conditions, giving good sight lines along the wall face. Current is generally mild, though it can strengthen, so intermediate divers should plan their descent and bottom time with that in mind. The site supports various reef species throughout the year, making it a consistent option regardless of season. Entry is by boat only.
