Surrounded by a lagoon that stretches to an offshore reef, and with forest-clad mountainous ridges, Raratonga is the most dramatic of the Cook Islands.
Muri Lagoon, to the southeast of the island, boasts a beautiful stretch of pristine sand.
From here, you can paddle into the shallow water to the uninhabited islets beyond, which are excellent for snorkeling.
The Muri Lagoon is a lagoon in the district of Ngatangiia on the eastern coast of Rarotonga in the Cook Islands. The lagoon is a significant tourist attraction and the largest tourism revenue earner in the Cook Islands, accounting for 25% of tourism bed usage on Rarotonga. In 2015 the Cook Islands government declared the environmental condition of the lagoon a national disaster. Wikipedia
