Blue Heron offers many different cruises within Fathom Five National Marine Park.  During the day the glass bottom boats tour over the 19th century shipwrecks that one can view through the crystal clear waters.  One cruise option is to take the glass bottom Blue Heron V over to Flowerpot Island to hike the trails, tour the historic lighthouse station property and explore the ancient sea caves.  Zodiac shuttles are also available for direct transportation to the island.  For those not wishing to hike, the best scenic tour of the area is aboard Canada's largest glass bottom boat, the Great Blue Heron.  It offers a 2 hour cruise through the many islands in the park during the day, and a sunset cruise down the Georgian Bay coastline every evening throughout the summer.  Departing daily from mid-May to October (weather permitting).  Visit our website for the complete schedule and rates.  On line reservations available.  Book early to avoid disappointment.
