About this site
Tikioki Marine Reserve lies on the south coast of Rarotonga in the Cook Islands, within a protected lagoon and outer reef area established as a marine sanctuary. The site sits near the Muri and Titikaveka area, where the lagoon meets a fringing reef break offering easy shore access for snorkelers and divers alike. Divers and snorkelers here have also reported whale sightings, though these are occasional rather than a guaranteed feature of the site.
