Brief
- Try local dishes such as ika mata (raw fish marinated in lime and coconut), fresh tropical fruit, taro and coconut-based foods. Avoid reef fish such as snapper because of ciguatera risk.

- Lagoon excursions, snorkelling and whale activities are weather- and sea-condition dependent. Follow local operator instructions and do not touch marine wildlife or coral.
Safety and health
- Mosquito-borne diseases: Dengue and Zika occur in the Cook Islands. Use repellent, wear covering clothing and use screened or air-conditioned accommodation. Pregnant travellers should take particular care to avoid Zika exposure. (

- Water and food: Tap water is not considered safe to drink. Use bottled or properly treated water, and avoid reef fish such as snapper because of possible ciguatera poisoning. (
- Medical and diving limits: Facilities on Aitutaki and other outer islands are very limited. Serious illness, injury or decompression sickness may require evacuation to Auckland, and there are no decompression chambers in the Cook Islands. Comprehensive travel insurance, including medical evacuation, is important. (
