This is a beautiful walk through the sand dunes of Oxwich National Nature Reserve is one of the most atmospheric coastal experiences on the Gower Peninsula, where shifting sands, sea air, and bursts of wildflowers create a constantly changing landscape. From the car park above Oxwich Bay, the path quickly slips away from the beach into a world of soft, rolling dunes. Marram grass bends in the wind, holding the sand together in sculpted ridges and hollows known as dune slacks. These sheltered dips are especially rich in life, where moisture gathers and rare plants take hold.
In September, the dunes and marshes support late wildflowers, including orchids, dune gentian and other coastal plants, alongside grasses turning golden as autumn approaches.
Insects are still active, especially butterflies, dragonflies and bees, feeding on remaining flowers in warm weather. Birdlife increases as autumn migration begins, with species such as warblers, waders, and winter wildfowl starting to arrive. In the sand dunes, you may also spot rare insects, dune beetles, and possibly reptiles like adders basking on warm days, while the surrounding wetlands and lakes attract herons, ducks, and reedbed birds.
The dunes give way to scrub, then glimpses of nearby Nicholaston Woods, where shaded paths contrast with the brightness of the sand. From higher points, you can look back across Oxwich Bay, a wide sweep of golden beach and blue water framed by dunes and cliffs.
Birdsong carries from marsh and woodland edges, and depending on the season, you might hear reed warblers or spot wading birds near the wetter areas behind the dunes. It’s a walk that feels both coastal and hidden—open sky and sea views one moment, then quiet, enclosed dunes full of flowers the next.

This walk will be co- led by Helen Nicholas and Charlotte Toft. Helen is a teacher and heritage educator, founder of Gower Unearthed CIC, leading community archaeology and outdoor learning across Gower’s prehistoric landscapes. Charlotte, an environmental conservationist, works in forest school and nature connection. Together, their walk honours their friend Hil Werker.
Hil loved the rich diversity of plant life in Oxwich dunes. Helen and Charlotte met Hil, exploring those dunes and over the years. Inspired, enthused and guided by Hil, they led an enjoyed festival walks together – particularly this one – and shared and continue to share, her celebration of the natural world and love of the countryside, the coast and Gower.
