Yes: Taha'a's coral garden is a shallow drift snorkel between two motu and Paipai Pass is a 25–30 m drop-off for trained divers, according to Tahiti Tourisme, but anchoring is restricted in parts of Moorea and we could not verify the current zones. The sea averages between 26.7 °C (August) and 29.0 °C (March) by NOAA's 1991–2020 means at our reference point, so it stays at 24 °C or more all year and by our rule of thumb a rash vest or 1–2 mm shorty is enough even in the coolest month.

## Snorkel and dive sites you can reach by charter boat in French Polynesia

| Site | Type | Where | What the source says |
|---|---|---|---|
| **Taha'a coral garden (Jardin de Corail)** | coral garden | West side of Taha'a, between two motu | Tahiti Tourisme describes crystal-clear shallow water between two motu on the west side of the island, where you drift with the current over the coral. ([Tahiti Tourisme](https://tahititourisme.pf/en-pf/activities/points-of-interest/jardin-de-corail-tahaa-en-en-pf-3342043/)) |
| **Paipai Pass** | reef and pass | Taha'a | Tahiti Tourisme describes a drop-off at 25–30 m for trained divers, with white-tip reef sharks; Taha'a has one dive centre and centres on Raiatea also dive there. ([Tahiti Tourisme](https://www.tahititourisme.com/activities/diving/tahaa/)) |

These are the sites we could document from official or labelled sources, not a full list. Fishing is a separate question: [fishing rules in French Polynesia](https://catamaranindex.com/fishing/french-polynesia/).

## Mooring, anchoring and park rules for your boat

- Moorea: since December 2020 anchoring is banned in a protection zone around an underwater seawater pipe in the inner waters of Papetoai. ([DPAM, Government of French Polynesia](https://www.service-public.pf/dpam/2020/12/03/creation-dune-zone-dinterdiction-de-mouillage-a-papetoai/))
- **[Not verified]** Moorea's wider anchoring rules (the maritime management plan and a 2025 government order, both contested in court): not verified.

## Can I scuba dive from the boat? Permits and dive centres

- **[Not verified]** Whether you must dive with a licensed dive centre: not verified.

## Park and mooring fees

| Fee | Amount | Status | Source |
|---|---|---|---|
| Lagoon or dive-site fees | Not verified | not verified | – |

## Underwater visibility

Tahiti Tourisme says visibility reaches up to 40 m at Taha'a's outer-reef sites (Ruutai, Tau Tau, Taputapu). This is the tourism board's description, not a measured average. ([Tahiti Tourisme](https://www.tahititourisme.com/activities/diving/tahaa/))

## What wetsuit do I need in French Polynesia?

From March's 29.0 °C our rule of thumb gives a **swimsuit or rash vest**; in August (26.7 °C) a **rash vest or 1–2 mm shorty**. The month-by-month column is in the [table above](#sea-temperature).

Our rule of thumb for snorkelling, applied to the monthly mean: 28 °C or more: swimsuit or rash vest; 26–28 °C: rash vest or 1–2 mm shorty; 24–26 °C: 3 mm shorty; 21–24 °C: 3 mm full wetsuit; 18–21 °C: 5 mm full wetsuit; below 18 °C: 7 mm wetsuit, or a drysuit for diving. Divers lose heat faster and meet cooler water at depth: go one band thicker. People feel cold differently; this is a guide, not a source's advice.

| Mean sea temperature | Our rule of thumb for snorkelling |
|---|---|
| 28 °C or more | swimsuit or rash vest |
| 26–28 °C | rash vest or 1–2 mm shorty |
| 24–26 °C | 3 mm shorty |
| 21–24 °C | 3 mm full wetsuit |
| 18–21 °C | 5 mm full wetsuit |
| Below 18 °C | 7 mm wetsuit, or a drysuit for diving |

## What we could not verify

- Moorea and Bora Bora anchoring zones in force for 2027.
- Rules for divers without a dive centre.
- Fees of any kind.
- Measured visibility (only the tourism board's description).

## How to read the labels

- **[Not verified]**: We could not confirm it. We leave it open rather than guess.
- No label: Read in an official text: government, park authority, ministry or official tourism board.

Sea temperatures are NOAA's; the wetsuit column, the 24 °C warm-water mark and any sum or comparison are ours and say so. Park rules change and some are seasonal: check with the park, your charter base or a local dive centre before you go.
