Parking details

Cadw says to park in the lay-by opposite the footpath to the tomb and gives its own what3words point for it; a gravel car park with a replica burial chamber lies about 60 m west on the same side of the lane. Cadw publishes no tariff or free statement, so the status is recorded as unknown, although visitors consistently describe the parking as free and easy to drive past. From the footpath a compacted and gravel track runs between hedges and over a small footbridge, about 640 m to the mound, 10 to 12 minutes each way, with some steps reported; the ground around the chamber is grass and uneven. No toilets or facilities; the nearest are at Plas Newydd, five minutes' drive. Grazing animals may be in neighbouring fields.

Driving pin: Cadw's own what3words lay-by point, 7 m from its map marker (which sits at the lay-by, not the tomb) and 16 m across the lane from the start of the footpath; the tomb is 390 m north-east. By road: north of the A4080, 1 mile east-south-east of Llanddaniel Fab and 2 miles from Llanfairpwll. National Cycle Network route 8 passes 1.8 km away.

About

Bryn Celli Ddu Chambered Tomb, Beddrod Siambr Bryn Celli Ddu, the Mound in the Dark Grove, is Anglesey's most famous prehistoric monument and two sites in one. Around 5,000 years ago a Neolithic henge was built here, a bank and ditch 21 metres across enclosing a circle of standing stones, several of which survive; later a passage tomb of the kind found around the Irish Sea replaced it, under a mound restored to 26 metres across. A long narrow passage leads to an octagonal chamber 8 feet wide holding a smoothed stone pillar, where human bones, arrowheads and a richly carved pattern stone were found in 1928 and 1929; a cast of the stone stands behind the mound. It is the only Anglesey tomb accurately aligned on the midsummer sunrise, when light shines down the passage into the chamber. Visitors stoop through the passage, look for the spiral carving and call it a highlight of the island. Park in the lay-by and walk about 650 metres along the hedged path.
