Adventurers can dive on the wreck of the SS Maitai, which was wrecked just offshore from Avarua in December 1916. With no lives lost, the 3393-ton vessel, owned by the Union Steam Ship Company, had traded between the Cook Islands and Tahiti.
Dedicated snorkellers will not be left out with some great sites, especially around the Muri Lagoon area.
Hikers and trekkers will enjoy the cross-island mountain walk that leads you through lush tropical rainforests, streams and waterfalls.
Other activities on Rarotonga include deepsea fishing, saltwater fly and light tackle sportfishing, whale watching, wind surfing, kitesurfing, sailing and golf.
There is no shortage of activities available, even if it's just lazing away the brilliant sunny days on the beach.
