The catamaran slips away from Ko Olina Marina as the sun leans toward the horizon, the ocean daring you to step into warm, clear water alive with color. Dolphins often thread the bow wake here—fast-moving, curious silhouettes that surface between snorkel groups—while coral gardens below host parrotfish and tangs in slow, confident arcs.
