Getting There

  • Car

    Drive to the free public car park near the Green Bridge of Wales, approximately 15-25 minutes from Pembroke town center. Note the access road passes through the Castlemartin military firing range and may be closed during live firing exercises. Checking the range status before travel is essential. Parking is free, but facilities are limited.

Geological Marvels Carved by Time

Elegug Stacks are two imposing limestone pillars standing about 25 meters tall, located just off the Pembrokeshire coast in southwest Wales. Originally connected to the mainland cliffs, these stacks were formed through thousands of years of coastal erosion that carved away the softer rock, leaving these dramatic isolated columns. The stacks are part of a coastline renowned for its limestone cliffs, arches, caves, and blowholes, illustrating the powerful forces of nature shaping the landscape.

A Sanctuary for Seabirds and Wildlife

The stacks serve as an important breeding ground for seabirds, particularly guillemots (from which the Welsh name "Elegug" derives) and razorbills. During the peak nesting season from May to early July, thousands of birds cram the ledges and tops of the stacks, filling the air with their calls. Nearby cliffs host fulmars, kittiwakes, and various gull species. Inland, the plateau supports diverse wildlife including reptiles, small mammals, and rare butterflies like the dark green fritillary, all thriving in this relatively undisturbed habitat.

Access and Military Restrictions

Elegug Stacks lie within the Castlemartin military firing range, which has limited public access due to live training exercises. Visitors must check the firing schedule before visiting, as the access road passes through the range and is closed during military activity. When open, a large free car park near the Green Bridge of Wales provides a starting point for walks to the stacks. The coastal path is well-defined and reasonably level, offering a scenic 1.5-hour one-way walk that also passes other landmarks like St Govan’s Chapel.

Surrounding Coastal Attractions and Scenic Walks

The stacks are part of the Pembrokeshire Coast National Park, an area celebrated for its unspoiled natural beauty. Nearby features include the Green Bridge of Wales—a spectacular 24-meter high natural limestone arch—and the Cauldron, a dramatic coastal blowhole. The coastal path offers breathtaking panoramas of the sea and cliffs, making it ideal for wildlife watching, photography, and enjoying fresh sea air. The area’s rugged charm is complemented by nearby beaches, ancient chapels, and peaceful picnic spots.

Visitor Experience and Practical Tips

Visitors to Elegug Stacks can expect a tranquil yet awe-inspiring experience, combining geology, wildlife, and coastal scenery. The best time to visit for birdwatching is late spring to early summer when seabirds are nesting. Facilities near the car park include picnic areas, but there are no direct amenities at the stacks themselves. The site’s remote and natural setting means visitors should be prepared for variable weather and bring suitable footwear for uneven terrain. Checking military firing times is essential to avoid access closures.

Conservation and Natural Heritage Importance

Elegug Stacks and the surrounding coastline are designated as a Site of Special Scientific Interest (SSSI), Special Protection Area (SPA), and Special Area of Conservation (SAC) due to their geological formations and rich biodiversity. The limited human disturbance, partly due to military use, has helped preserve this unique habitat. Conservation efforts focus on protecting the nesting seabird populations and maintaining the integrity of the limestone cliffs and coastal ecosystems.
