More ways to explore the area's outdoor wonders
The catamaran slips out of Bayside Marketplace with the city skyline shrinking behind you and Biscayne Bay opening like a wide, sunlit road. Salt air tugs at hair and towels; the bay’s small islands—Flagler Monument Island among them—stand low and bright against a blue ruled by speedboats and seabirds. Guests spread out on the deck, swap sunglasses, and pick their toys: kayaks, SUPs, a giant sponge-like mat that floats like a lazy island.
