Te Ava Piti

Te Ava Piti — “The Small Pass” — is an Advanced pass drift dive in the barrier reef surrounding Raiatea and Taha’a, French Polynesia. Despite its name implying small scale, the pass channels powerful tidal flows and reliably aggregates large numbers of grey reef sharks and other pelagics.
Overview
Te Ava Piti is one of the key pass dive sites in the Raiatea-Taha’a lagoon system. The pass cuts through the barrier reef and measures narrower than the main passes, which concentrates tidal flow into a faster current. On incoming tides, oceanic water surges through the channel at 2–4 knots, creating drift conditions and bringing excellent visibility of 30–40 metres. The bottom of the pass lies at 25 metres before ascending into the lagoon shallows. Water temperature is 27–28°C throughout.
What to Expect
Grey reef sharks are the defining species of Te Ava Piti — groups of 10 to 30+ individuals aggregate in the channel to feed on the fish carried in by the current. Encounters are close and active as the sharks work the current. Blacktip reef sharks join the grey reef sharks near the lagoon side of the pass. Eagle rays and marble rays ride the current gracefully alongside divers being swept through. Schools of barracuda spiral in columns in the mid-channel, and bigeye jacks hunt cooperatively at the channel walls. The narrow pass geometry intensifies all the activity, making encounters with multiple species simultaneous.
Conditions
- Best season: April–November; year-round on right tidal timing
- Visibility: 30–40 m on incoming tide
- Current: Strong (2–4 knots); must be timed to incoming tide
- Water temperature: 27–28°C
- Entry: Boat dive; drift exit
Tips
Dive only on an established incoming tide for best shark activity and visibility. The narrow pass requires attention to depth — avoid being swept against the channel walls. Carry and deploy an SMB at the end of the drift for boat pickup. This site is not suitable for divers uncomfortable in strong current.
