Even on a tight schedule, Jet Ski / Watersports on Biscayne Bay earns the hours.
Allow 1–2 hours.
A genuine adrenaline highlight — open throttle across the bay with the skyline and Star Island mansions around you, and the breeze is welcome in the heat. The catch: it's pricey by the hour, operators add fuel/insurance fees, and choppy water or a guided 'follow-the-leader' format can dampen the thrill.
