Open 10am to 4pm all year, last admission 30 minutes before closing; closed 24, 25 and 26 December and 1 January. Cadw asks visitors to come only during these hours, chosen for safety so that there is enough light. Cadw may close monuments at short notice in extreme weather.
Terrain level 3, moderate: an exposed field site that may be slippery or muddy underfoot, so wear suitable footwear; guardrails protect the stones and climbing on them is not allowed; neighbouring farmland may have grazing cattle or other animals. No toilets, shop or other facilities. Drones are not permitted.
