In 1968, the proprietor of Charlotteville Estate presented a group of tiny islands comprising of The Giles, including: Melville, Marble, and London Bridge, to the Government of Trinidad and Tobago for the establishment of a wild-life sanctuary. The largest of these isalnds, situated about a 1/2 mile off the north-east coast, is the Melville Island. It is one of the most important seabird breeding grounds in the South-west Caribbean and some of the birds to be found there are Noddy Terns, Brown Boobies, Red-Footed Boobies, Red-Bill Tropic Birds, White Tropic Birds, Frigate Birds and lots of Seagulls. Several other species of seabird feed and nest on the island.
Boats can be hired for excursion trips around these islands from the seaside village of Speyside or Blue Waters Inn nearby and also from Charlotteville, the most northern seaside village of them all.
