Lord Howe Island Marine Park

The marine park surrounding Lord Howe Island contains the world's southernmost

 barrier coral reef.

 In here swimming, snorkeling and scuba diving are all popular

 in the crystal waters of the park, and boat trips and diving tours operate 

from the island.

The small human population and limited visitor numbers have 

ensured that marine resources are only lightly exploited,

 so swimming and snorkeling with myriad colourful fish is the norm.
