April–October is the dry, cooler season — ideal for Aitutaki lagoon tours (by boat or glass-bottomed kayak), snorkelling, and hiking Rarotonga's interior (Te Rua Manga — The Needle). November–March is cyclone season. Aitutaki's lagoon is consistently voted among the world's most beautiful — the turquoise-to-teal gradient is extraordinary.

Dress Code

  • Casual beach wear throughout
  • Smart casual for restaurants and evening dining

Social Etiquette

  • Cook Islanders are among the most warm and genuinely welcoming people in the Pacific — the islands receive fewer tourists than their quality deserves
  • Aitutaki can only be reached by small prop plane from Rarotonga — the 45-minute flight is part of the experience
  • Island nights (traditional dancing, drumming, and a feast) are held regularly on Rarotonga — genuinely spectacular
  • The Cook Islands is a self-governing nation in free association with New Zealand — Cook Islanders are NZ citizens

Local Laws

Laws change. Verify current rules with your country's official travel advisory before departure.

  • LGBTQ+ same-sex relationships were decriminalised in 2023 — a significant milestone; social attitudes warming
  • Marine protected areas require permits — enforced for diving and fishing
