The Isle of Sheppey is an island off the coast of Kent, neighbouring the Thames Estuary. Sheppey is separated from the mainland by a channel called The Swale. The towns and villages throughout Sheppey have centuries of rich maritime and aviation histories. The traditional holiday destinations of Sheerness, Minster and Leysdown attract visitors throughout the year. Beaches at Leysdown and Minster Leas boast Seaside Awards, whilst Sheerness Beach has a Blue Flag Award, a promenade and traditional seaside facilities including amusement arcades. Sheerness also boasts an 18-hole golf course. Barton's Point Coastal Park features 40 acres of outstanding natural beauty, a salt-water lake, a section of the Sheppey Cycle Route and more. The nature reserves and wildlife habitats on the Isle are also popular attractions. About 200 shipwrecks are recorded around the coast of Sheppey; the most famous being the SS Richard Montgomery. Her three masts are always visible above the water.
