Mayreau is the smallest inhabited island in the Grenadines, with an area of about 1.5 sq. miles, and a population of less than 300. The island is mostly populated by fishermen and supported by tourism. The population is centered in Old Wall village, located on a hilltop in the southwest of the island. It is accessible by boat. Electricity is provided by a Vinlec, the state electricity company. There is a single lane concrete road leading from Saltwhistle Bay to Saline Bay and through the village, and a new series of simple roads have been built to allow access to the island’s eastern beaches.
The top of the island is crested with the small school, several restaurant/bars, two provisioning shops, and two churches. The school has about 50 students in Grades 1-6.
The island gets much of its water from three catchments set on the east side of the island. Saline Bay is named for the salt pond just east of the sandy beach. Salt was harvested and exported in times past but is now only harvested for local use. Mayreau also has a small resort area; Saltwhistle Bay. It is a popular and beautiful spot for anchoring yachts. From the crest of the hill beside the Catholic Church, there is a beautiful overlook of the Tobago Cays, Canouan, and Union Island.
