Cadw names the Porth Trecastell car park, the beach car park of about 50 spaces beside the A4080 at Cable Bay. A visitor in June 2026 reports a pay-to-park meter and OpenStreetMap marks it as charged, but neither Cadw nor Anglesey County Council publishes the operator or tariff, so the status is recorded as unknown; bring change in case. From the car park the coast path rounds the cove and climbs onto the headland, a few hundred metres with a short climb; a snack van is often in the car park.
Driving pin: the Porth Trecastell car park, 436 m from Cadw's marker on the headland. By road: just off the A4080, 2 miles north-west of Aberffraw. By rail: Ty Croes, 3.2 km. Buses between Aberffraw and Rhosneigr run only a few times a day. National Cycle Network route 8 passes 7.3 km away.
Barclodiad y Gawres, the Giantess's Apronful, gives a revealing and surprising glimpse into the lives of our ancient ancestors from a spectacular clifftop above Porth Trecastell near Aberffraw. The 90-foot earthen mound is a modern reconstruction, but beneath it lies a 23-foot passage leading to a cross-shaped chamber, where the cremated remains of two men were found. Among the stones of the chamber are five etched with intricate zigzags and spirals; the only other tomb in Britain with such megalithic art is Bryn Celli Ddu a few miles away. The passage is gated, so visitors look along it to the decorated stones, which reviewers say are lit by solar-powered lights, and Cadw opened the chamber on booked guided tours on selected summer dates in 2026. It is a short walk and small climb from the beach car park, exposed and with great sea views. Dogs on short leads are welcome on the headland, and the Wales Coast Path's Aberffraw to Rhosneigr walk passes the tomb.
Enjoy a guided tour as part of your visit to Barclodiad y Gawres Chambered Tomb on selected dates between May and August 2026. Find out more and book tickets Please be aware that due to coastal erosion, the area around the monument needs extra care when using the lower coastal path. See the official page for the full notice.
Free entry
The tomb can be viewed externally throughout the year, 10am to 4pm; the gated passage lets visitors see the decorated stones inside. The chamber itself is opened only on Cadw's booked guided tours, which ran on selected dates from May to August 2026 and are over for the year (a notice on Cadw's page still advertises them); check Cadw's events for the 2027 season. No admission charge to the site. Cadw may close monuments at short notice in extreme weather.
Terrain level 3, moderate: an exposed headland that may be slippery or muddy, with heights and high winds, reached by the coast path from the car park. Health and safety alert (17 October 2026): coastal erosion means extra care is needed on the lower coastal path around the monument, though the path to the tomb itself is unaffected. Neighbouring farmland may have grazing animals. No toilets or facilities. Drones are not permitted.
Dogs: Dogs on short leads are welcome on the headland around the mound; the chamber is gated to everyone. Not specific to this site; the chamber is gated to everyone.
