A 4-Day Oahu Itinerary That Goes Way Beyond the Tourist Trail
Mermaid’s Cave sits on Oahu’s leeward coast, and you can only get in at low tide — the turquoise pools inside are sealed off the rest of the time, which is exactly the kind of place that doesn’t make it onto a standard Waikiki itinerary. This four-day plan is built around stops like that one: places that require a bit more effort, a tide chart, or a willingness to skip the famous photo spot next door. It suits travelers who’ve either done Oahu’s headline stops before or simply want a different four days than the Diamond Head-Pearl Harbor-Hanauma Bay
