Parking: Coronado Colon Hydrotherapy is on the corner of YNEZ and B Avenue upstairs on the second floor of the DEEP BLUE SEA SANCTUARY. Parking is 25 cents an hour and free 6pm and after, as well as Sundays. Please do not park at the 30 minute meters in front of the post office. You will not have enough time in those spots. Look for meters with 1 hour or more when parking. They are located right in front of the Deep Blue Sea Sanctuary and along perpendicular streets. Please allow plenty of time to find a parking place before your appointment.
