Boat

Many hotels, marinas, and yacht clubs rent slips short-term. Call ahead, because available space is limited. The San Diego and Southwestern yacht clubs have reciprocal arrangements with other yacht clubs.

Flagship Cruises takes you between Downtown and Coronado in a nostalgic, old-school ferry every hour from 9 am to 9 pm. The ride lasts about 15 minutes and costs $5 each way; bicycles and Segways are free.

San Diego SEAL Tours, operated by Old Town Trolley, combine the best of land and sea, departing from Seaport Village daily. After exploring picturesque San Diego neighborhoods, the bus-boat hybrid rolls right into the water for a cruise around the bay. The $42 tour is narrated with fun facts, too.
