Rarotonga Reef Sub: A Review of our semi-submersible adventure.

We had a great time on the Raro Reef Sub!

Rarotonga has such stunning views of the ocean from quite literally anywhere around the island but there is something wondersome about being out on the Pacific Ocean and looking back at the island from a sea-perspective.

Giant Trevally.

We saw lots of beautifully-coloured tropical fish swimming in the coral gardens near the shipwreck and many, many Giant Trevally. 

Big-fish-wise, if you are lucky enough to be here in whale season from August to November you might spot the incredible humpback whales that frequent the waters here at this time.  

But if not, there is plenty of other marine life to see (and even some seriously impressive sized fish to see before even leaving the wharf!).

Where abouts in Rarotonga does it go? 

The Rarotonga Reef Sub departs from Avatiu Harbour and heads out from the port area to the right of the harbour mouth.

Not too far out you will see ‘The Boiler’ as it is referred to by locals. This is in fact part of the infamous Maitai shipwreck.

The Reef Sub takes you around the shipwreck looking at the remains and all of the fish and marine life in the area.

Find the Raro Reef Sub

You will find the Raro Reef Sub at Avatiu Harbour, just 5 minutes walk (to the west) from the central Punanga Nui Markets. 

How is it with children? 

Our kids loved the Raro Reef Sub! I was slightly anxious they might feel seasick down below deck in the submarine part of the vessel.

But they loved it and didn’t want to come up!

The boat feels safe as it travels slowly and has enough seats for the passengers it takes.

There are plenty of handrails to hold onto and the kids enjoyed climbing up and down the ladder to check out the submarine views below.

Some of our favourite tours we can personally recommend since living here include:

  • Find the best swimming beaches: It’s no huge surprise that this tropical island has some seriously fantastic swimming beaches. But in case you are wondering which side of the island to check out first, read our guide to Rarotonga’s best swimming beaches here.
  • A reef or ridge walk with Ariimoana: Amazing local tours and opportunity to learn about life in Rarotonga from local guides, Kura and Jacopo.  If you haven’t already read these blog posts and checked out their tours; go and look now! 
  • Hike to the Needle: The Cross Island walk is Rarotonga’s most famous hike. Explore the inland jungle and rivers with some seriously rewarding ocean views.
  • Rongohiva Speed Boat: Another great water activity that’s lots of fun and in the right season even brings the chance of seeing whales from beyond the reef.
  • Te Vara Nui Cultural Show: An impressive taste of local Cook Island culture with performances, dancing, music and a buffet dinner. 
  • Muri Night Markets: A fun and tasty way to spend the evening in Rarotonga.  (I recommend trying a soursop ice-cream from Be Fruitful!).
