Best Locations for Marine Encounters

Rarotonga is surrounded by a protective reef, creating calm lagoons teeming with life. Here are some of the best snorkelling and scuba diving spots to explore:

1. Fruits of Rarotonga (Tikioki Marine Reserve)

   One of the most popular snorkelling spots on the island, this marine reserve is famous for its crystal-clear waters and dense coral gardens. Expect to encounter parrotfish, butterflyfish, wrasse, and even giant clams. Beginners will find it safe and shallow, while more experienced snorkellers can venture further out towards deeper channels.

2. Aroa Lagoon Marine Reserve

   Located on the southwest coast, Aroa Lagoon is a haven for families and beginner snorkellers. The calm, shallow lagoon is protected from boat traffic, ensuring a relaxed environment. Colourful reef fish like Moorish idols and triggerfish are abundant, and the sandy entry points make it easy to access.

3. Black Rock

   Known for its dramatic volcanic rock formations onshore, Black Rock is also a rewarding snorkelling area. Turtles are sometimes spotted here, gliding gracefully through the lagoon. It’s a picturesque spot for both marine encounters and sunsets.

4. Avaavaroa Passage

   For the more adventurous, Avaavaroa Passage is one of the best scuba diving locations. Here, you can dive with green turtles and eagle rays in deeper waters. With strong currents, this site is recommended only for confident divers with guides.

5. Mataora Wreck

   Wreck divers will appreciate the Mataora, a ship that was deliberately sunk to form an artificial reef. Located off the northern coast, it’s now home to schools of snapper, trevally, and colourful corals. The wreck provides an exciting contrast to natural reef diving.

6. Koromiri and Taakoka Motus (Muri Lagoon)

   Snorkel around these tiny islets in Muri Lagoon for an easy and family-friendly experience. Shallow waters and plenty of tropical fish make this a great spot for a few hours of relaxed exploration.

Seasonal Conditions and What to Expect

Rarotonga’s marine environment is accessible year-round, but conditions can vary depending on the season:

Dry Season (May to October)

This is the peak travel season with cooler, drier weather. Visibility underwater is excellent, often exceeding 30 metres for divers. Water temperatures average 24-26°C, perfect for long snorkelling sessions.

Wet Season (November to April)

The warmer, wetter season brings slightly reduced visibility due to rainfall, but water temperatures rise to 27–29°C. Marine life is still abundant, and the lagoons remain calm most days. This season also sees the migration of humpback whales (July to October), with chances of spotting them on the outer reef.

Tidal Changes

Always check tides before heading out. At low tide, some reef areas can be too shallow, while high tide often provides the best conditions for snorkelling.
