Carnac Island is an A‑class nature reserve sitting between Rottnest and Garden Islands; its limestone shelves and pockets of seagrass record Holocene coastal change and host diverse coastal life. European mariners visited in the 19th century, but modern use prioritises wildlife protection—tour operators brief visitors on respectful distance and behavior before water activities begin.
A typical half‑day run balances instruction, wildlife interpretation, and choice: a quick swim, guided snorkel over rocky reefs, or paddling on SUPs and kayaks provided by the operator. If conditions allow, the return leg is sail-only—quiet, wind-driven and restorative.
Practical guidance: the trip lasts about four hours and requires a moderate fitness level for boarding and getting in and out of kayaks or the water. Water temperatures vary; bring a wetsuit or spring suit in cooler months. Use reef‑safe sunscreen, secure footwear for boarding, and pack a light wind layer for the open-water sail. Expect good visibility in summer but occasional currents on the island’s exposed sides. This is not a close-contact sea lion swim—observe from a safe distance. Arrive 15 minutes early, follow crew instructions, and leave no trace—wildlife and reefs rely on it.
moderate.
4 hours.
Moderate fitness—comfortable boarding small craft, basic swimming ability, and short surface swims for snorkelling.
No—this is not a swim-with-sea-lions tour; guides provide interpretation and sightings from a safe distance for both visitor and animal welfare.
Water is warmest in summer and cooler in winter; a spring suit or short wetsuit is recommended outside summer months for comfort during snorkels.
Yes—operators provide basic instruction and quality gear; participants should be comfortable in the water and able to follow safety briefings.
Tours may be cancelled for safety in high winds or seas; check cancellation policies and consider that operators may reschedule depending on conditions.
Carnac Island is designated an A‑class nature reserve and its limestone formations reflect coastal processes since the last sea‑level rise; it’s been visited by sailors since European exploration of the 19th century.
Landing and close approaches to wildlife are regulated; visitors should use reef-safe products, avoid feeding or disturbing animals, and follow operator briefings to minimise impact.
Charter 1 operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
