St. Agnes, Isles of Scilly
St Agnes joins the island of Gugh by a tombolo, a kind of sandbar, called the Gugh Bar, which is exposed only at low tide. The Gugh is inhabited, with some three residents. The two islands of St Agnes and Gugh together have a population of 85 residents recorded in the 2011 census (73 were recorded in the 2001 census) and a landmass of 366 acres (148 ha). Without the Gugh included, St Agnes is marginally smaller than Bryher in either population or area; however if Gugh is included with St Agnes, it is Bryher that is marginally smaller in area and population.
In earlier times many men from St Agnes earned a living as pilots, guiding transatlantic liners and other vessels through the English Channel. Now the mainstay of the economy is tourism, together with some bulb farming. Accommodation is limited, and St Agnes is the only populated island in the Isles of Scilly which has no hotel. However, it has a few B&Bs and self-catering cottages, an ice cream shop, a campsite, a small post office and general store and a gift shop. It also has a pub (the Turk's Head) and a café. .
The main population centre is in the north and middle of the island. The southern end of the island is covered by the heather moorland of Wingletang Down.
