2. Scuba Diving at the Rarotonga Wall

For those wanting to explore the deeper realms of Rarotonga’s marine life, scuba diving at the Rarotonga Wall is a thrilling choice. This natural wall, dropping over 4,000 metres into the ocean, is famous for its spectacular underwater landscapes and vibrant biodiversity. Scuba divers can swim alongside schools of barracuda, eagle rays, and even reef sharks. With its unique underwater topography, including steep drop-offs and caverns, the Rarotonga Wall is perfect for both novice and experienced divers seeking an awe-inspiring underwater adventure.

3. Paddleboarding and Kayaking

One of the best ways to appreciate Rarotonga’s serene lagoons and scenic coastlines is from a paddleboard or kayak. Glide over the tranquil waters of Muri Lagoon or explore hidden coves and bays around the island. Paddleboarding is a relaxing yet engaging way to stay active while enjoying stunning lagoon views. If you’re new to paddleboarding, the calm waters of Muri Lagoon make it an ideal spot to try this activity. Kayakers, on the other hand, can venture further to discover small islands (motus) scattered within the lagoon, offering a unique perspective of the island’s natural beauty.

Tip: Many resorts and water sports centres offer paddleboard and kayak rentals. Consider booking during early morning or late afternoon for a peaceful experience with fewer crowds.

4. Lagoon Cruises and Glass-Bottom Boats

For a leisurely exploration of Rarotonga’s marine environment, consider hopping on a lagoon cruise or a glass-bottom boat tour. These cruises typically take you to prime snorkelling spots while letting you admire the underwater world without needing to get wet. Glass-bottom boats allow for an incredible view of coral gardens and colourful fish below, while lagoon cruises often feature live music, traditional performances, and a delicious island-style lunch. It’s an excellent option for families, couples, or anyone who wants a laid-back water experience with a touch of local culture.

Tip: Some tours offer a barbecue lunch on a motu, combining delicious food with an unforgettable island experience.

5. Deep Sea Fishing

Rarotonga's deep-sea fishing opportunities draw anglers from around the world. The island’s surrounding waters are home to marlin, mahi-mahi, yellowfin tuna, and wahoo, making it a top destination for sport fishing. Several charter companies provide half-day and full-day fishing trips with experienced crews who know the best spots for big catches. Whether you're an experienced angler or a first-timer, Rarotonga’s fishing charters cater to all levels, ensuring a memorable day out on the ocean.

Tip: Fishing trips can be popular during peak seasons, so it’s wise to book in advance to secure a spot.

6. Kite Surfing and Windsurfing

For thrill-seekers, Rarotonga’s steady trade winds create perfect conditions for kite surfing and windsurfing. Both sports are best enjoyed in Muri Lagoon, where shallow waters and consistent winds provide ideal conditions for both beginners and experienced riders. Kite surfing offers an exhilarating experience as you harness the power of the wind to glide across the lagoon, while windsurfing combines elements of sailing and surfing. Both activities promise an adrenaline-pumping adventure set against the breathtaking backdrop of Rarotonga’s lagoons and surrounding islets.

Tip: If you’re new to kite surfing or windsurfing, look for local instructors who can offer lessons and equipment rental.

7. Whale Watching (Seasonal)

From July to October, Rarotonga becomes a prime spot for whale watching as humpback whales migrate through the Cook Islands. Witnessing these majestic creatures breach and play in the waters surrounding Rarotonga is a truly awe-inspiring experience. Several operators offer whale-watching tours, allowing you to get close to these gentle giants while learning about their behaviours and migratory patterns.

Tip: Whale-watching tours are seasonal, so if you’re visiting Rarotonga during the winter months, don’t miss out on this unforgettable experience.

8. Beachcombing and Relaxing

Not every water activity requires diving in; sometimes, a simple stroll along Rarotonga’s stunning beaches can be just as rewarding. The island’s soft sandy shores and clear, shallow waters make it easy to explore tidal pools, find unique shells, and enjoy the sound of gentle waves. Set up a hammock or a beach blanket, and take in the tranquil beauty of Rarotonga’s beaches.
