Why it's Wildland
6.4From a forest car park, this walk crosses Newborough’s shifting coastal landscape to the tidal finger of land at Ynys Llanddwyn, where a ruined church, holy well and two lighthouses recall centuries of maritime life.
The appeal is the changing journey: forest planted to hold shifting dunes gives way to beach, wildlife-rich coastal habitats and a historic tidal peninsula. It offers more to discover than a simple lakeside stop, with the route and tide shaping the experience.

The experience
A 4-mile return walk from Llyn Rhos Ddu car park to Ynys Llanddwyn, with a choice of forest or beach on the outward leg. The route combines coastal scenery, wildlife habitat and historic remains; access to the peninsula is affected by the highest tides.
Things to do
Walk through Newborough Forest
Take the forest option from the start towards Ynys Llanddwyn. The forest was planted to help stabilise shifting sand dunes and is now habitat for red squirrels and roosting ravens.
Part of the 4-mile return walk
Explore Ynys Llanddwyn’s historic remains
See the remains of St Dwynwen’s Church, the nearby holy well, two 19th-century lighthouses and restored pilot’s cottages. The peninsula is accessible at all but the highest tides, according to the route source.
Allow time within the walk
Look for coastal wildlife
Newborough’s forest, dunes, marshes and shores support varied wildlife. The route information mentions red squirrels and roosting ravens; Natural Resources Wales describes the Cefni Estuary and pools behind Pen Cob as a bird and wildlife sanctuary.

Verified history
Newborough Forest’s Corsican pines were planted between 1947 and 1965 to provide timber and stabilise shifting sand dunes. On Ynys Llanddwyn, the route source identifies the remains of St Dwynwen’s Church, two 19th-century lighthouses and restored pilot’s cottages. The pilots rowed out to guide ships through dangerous sandbars between Caernarfon and Abermenai Point and also manned the local lifeboat.
Folklore & legend
Local legend says eels in the holy well could predict a visitor’s romantic future: if they were jumping, the visitor was sure to be lucky in love. This is folklore, not a verified prediction.
