Shoreline schedules 30-minute lake cruises every half-hour from its three dock locations: the Shedd Aquarium, Navy Pier, and Buckingham Fountain in Grant Park. Shoreline has also gotten in on the popularity of architecture tours by offering its own version, narrated by an architectural guide (with higher prices than their regular tours). A water taxi also runs every half-hour from Navy Pier to both the Sears Tower and the Shedd Aquarium. One-way tickets for the water taxi are $6 for adults, $5 for seniors, and $3 for children under 12; all-day passes cost $12 for adults and $6 for children.
