Ballyryan, Limestone climbing area in The Burren, Ireland

Ballyryan is a small, mostly west-facing limestone crag in the Burren, County Clare, beside the Ailladie car park on the R477 road. Its routes are mostly about 10–12 metres high, ranging from Diff to HVS, with a few harder lines such as Agony Aunt (E2 5c) and Crack 90 (E3 6a).

Ballyryan's first climbing routes date from the early 1970s, including Whose Corner (VS 4c) and Whacky (HS). Irish Tiglin climbing groups ran courses on many routes without recording their ascents, so the early history is partly undocumented. Later, proximity to Ailladie led to harder lines such as Agony Aunt (E2 5c) and Crack 90 (E3 6a).

Ballyryan takes its name from the townland where the crag stands; the Irish form is Baile Uí Rinn, "Ring's homestead". Locals also call the cliff Ballyreen, the spelling used for the nearby Ailladie sea-cliff, also known as the Ballyreen Cliffs or Ballyreen Point. The crag sits beside the Ailladie car park on the R477 road.

The site sits near the R477 road south of Fanore with accessible parking nearby. Weather conditions change frequently in the Burren, so climbers should be prepared for shifting wind and rain.

Most Ballyryan routes are about 10–12 metres high, not 25, and the hardest lines are Agony Aunt (E2 5c) and Crack 90 (E3 6a). Irish Tiglin climbing groups ran courses on many routes without recording their ascents, so some early lines have no logged first ascent. Routes are often described as difficult to protect when leading, and novices can toprope for safety.
