Spinner Dolphins: Lanai, HawaiiWhile divers often link Hawaii synonymously with humpback whales, which congregate there every winter, most will never see these hulking creatures below the surface. More common — and more exciting when they arrive en masse — are encounters with spinner dolphins that cruise the coast year-round, sometimes in pods hundreds deep. When a pod that size approaches, you’ll hear it coming several minutes before you see anything: a building din of high-pitched clicks and squeaks. As the cacophony crescendos, the dolphins emerge from the blue in a seemingly endless line that undulates like a bullet train that’s just jumped its tracks. After five to ten minutes, the final stragglers pass by, the chatter fades and the whole impressive display disappears just as quickly as it arrived.
