By day or by night, a cruise on Biscayne Bay is a leisurely way to see the city. Island Queen yachts casts off from the Bayside dock between 10:30 a.m. and 7 p.m. on 90-minute cruises with chatty bi-lingual commentary on local sights and where the rich and famous live. The ships' lower salons are air-conditioned with wrap-around windows while an awning shades the upper deck. The Island Queen also offers dance cruises, trips up the Miami River, sails at sunset, fishing cruises, a water taxi between Miami and Miami Beach and jetboat and speedboat rides.
