Historic Coastal Stronghold and Landscape

The Deer Park is named after an unsuccessful attempt in the late 18th to early 19th century to establish a deer enclosure here, but no deer were ever introduced. Instead, the site is dominated by the remains of a substantial Iron Age promontory fort, dating back over 2,000 years. This fort, the largest of its kind in South Wales, is perched on towering cliffs that overlook the sea, providing natural defenses that once protected its inhabitants. Visitors can explore the ramparts and earthworks, imagining the strategic significance of this coastal stronghold.

Stunning Wildlife and Marine Views

From the clifftops of the Deer Park, visitors enjoy spectacular panoramic views across St Brides Bay to Skomer Island, Skokholm, and Ramsey Island. These islands are internationally renowned nature reserves, hosting dense populations of seabirds such as Manx shearwaters, puffins, razorbills, and guillemots. The surrounding waters are a Marine Nature Reserve, frequented by Atlantic grey seals—especially in late summer when seal pups are visible on the beaches below. The area also supports peregrines, choughs, curlews, and other coastal birds. Jack Sound, the stretch of water separating the mainland from Middleholm Island, is a known feeding ground for gannets and porpoises, with occasional dolphin sightings.

Ecological Management and Landscape Character

The Deer Park’s coastal heathland is actively grazed by a herd of Welsh mountain ponies. Their grazing helps prevent overgrowth of invasive plants such as bramble, gorse, and bracken, which would otherwise threaten the short grassland habitat essential for insect-rich biodiversity. This management supports species like the chough, which rely on open grassland to feed. The rugged terrain includes fields, rocky cliffs, and a minor road, offering a reasonably level but exposed walking experience that connects visitors intimately with the Pembrokeshire Coast’s wild character.

Geological and Archaeological Significance

The geology of the Marloes Peninsula is striking, featuring ancient Silurian volcanic lavas and sandstone formations with visible folds and faults. Nearby Gateholm Island, visible from the Deer Park, is a tidal island with prehistoric settlement remains and an Iron Age fort that was featured in archaeological excavations. The peninsula’s rich archaeological heritage adds a deep historical dimension to the natural beauty of the site.

Visitor Experience and Seasonal Highlights

The Deer Park is a favored spot for wildlife enthusiasts, photographers, and walkers. The best time for seal spotting is late summer when pups are born, and birdwatchers can observe diverse seabird colonies year-round. The coastal walks here offer a sense of remoteness and connection to nature, with opportunities to see porpoises and even dolphins in the surrounding waters. The site is accessible year-round during daylight hours, though weather can be rugged and windy. Visitors are advised to keep dogs on leads to protect sensitive wildlife and grazing livestock.

Conservation and Management by the National Trust

Managed by the National Trust as part of the Marloes Sands and Mere estate, the Deer Park benefits from conservation efforts that balance public access with habitat protection. The surrounding area is designated as a Site of Special Scientific Interest (SSSI), Special Area of Conservation (SAC), and Special Protection Area (SPA), reflecting its importance for wildlife and natural heritage. The National Trust provides information boards and maintains walking paths to enhance visitor understanding and enjoyment while preserving this unique coastal environment.
