The Cook Islands pack two very different lagoons into one short hop: Rarotonga’s Muri, calm and motu-studded, wadeable straight from a beach towel, and Aitutaki’s, a 12-kilometer stretch of turquoise ringed by a reef so photogenic it’s been used to sell more than one airline’s ad campaign. This 5-day route splits the week between the two — a rainforest trek to Rarotonga’s basalt spire, a night market of grilled mahi mahi, and a lagoon cruise to a motu with its own foot-shaped passport stamp — using the same resorts, tour operators and inter-island flights real travelers book.
