The site's name, 'Duver', is a corruption of the French word 'dune' or 'douvre', reflecting the sandy terrain.
The Old Church of St Helen, originally built in the 12th century, was abandoned and largely destroyed in the early 18th century due to persistent coastal erosion.
The surviving church tower was reinforced by Trinity House in the 18th century to serve as a beacon for ships navigating the difficult approaches to Portsmouth and the Solent.
St Helens Duver was the original site of the Royal Isle of Wight Golf Club, which was established in 1882 before the course moved to Bembridge.
The habitat supports rare flora such as the Sea Stock and the pyramidal orchid, which thrive in the sandy, saline-influenced soil.
St Helens Duver is a protected coastal spit located on the eastern side of the Isle of Wight, situated between the mouth of the River Yar and the Solent. This Site of Special Scientific Interest (SSSI) comprises a diverse landscape of sand dunes, salt marshes, and coastal grasslands. The area was historically used as an 18th-century golf course, the oldest in the Isle of Wight, before being reclaimed by natural coastal vegetation. The site features the remains of the Old Church of St Helen, specifically a distinctive ruined tower preserved as a landmark. The coastline here offers views toward Bembridge Harbour and the surrounding Solent waters. It provides a natural habitat for various rare plants and butterflies, including the Adonis Blue. The area is managed by the National Trust for conservation and public walking. It is a largely flat, open-access landscape without formal infrastructure or facilities.

Wear sturdy, waterproof footwear as the paths can be sandy, uneven, and muddy depending on the tide.
Bring binoculars for birdwatching, as the adjacent harbour attracts migratory waders.
Plan your visit around low tide if you wish to explore the shoreline and the full extent of the mudflats.
Do not attempt to walk across the mudflats or harbour channel at mid-to-high tide, as the incoming water is fast and dangerous.
Keep dogs under close control to protect nesting ground-birds and sensitive dune vegetation.
