Quarantine Bay Beach Cooktown

Quarantine Bay owes its name to the fact that it was first used as a quarantine section for passengers of ships with diseases. Covered with pebbles and shells, this beach is fantastic for fishing and swimming thanks to its warm and shallow waters. Quarantine Bay is located just seven kilometres south of Cooktown, off the main Highway to Cairns.

So say all references online, however, in actuality, there were no quarantine locations here..as the bay waters were too shallow for Quarantine vessels, and also the threat of being able to walk ashore at low tide. Quarantine was at Leprosy Creek in Cooktown, not at Quarantine Bay. There were leprosy cases at Cooktown in 1897 to 1908. You can do a tour up Leprosy Creek with Riverbend Tours
