Couples can retreat into a different world for the day by exploring Hawaii’s mountains. The meandering, rain forested trails of the Koo’lau Mountains are a quick drive from Honolulu—the Mariner’s Ridge Trail opens to reveal a remarkable view over Oahu’s windward side that inspires sighs from even the most seasoned hikers. Wanderers on the Big Island will connect with Pélé, the volcano goddess, who expresses her longing for the young chief Lohiau by heaving up lava and forming new mountains. On Kauai, a trip to the Waimea Canyon allows couples to daydream together in technicolor by taking in the canyon’s saturated greens, reds, and oranges from overlooks scattered throughout the trail. * While this trail has recently closed (see Erin's comment below), "try Kuliouou Ridge Trail in Aina Hina."
