The Twelve Bens or Twelve Pins (Irish Na Beanna Beola) is a small mountain range of sharp-peaked quartzite ranges located northeast of Roundstone in Connemara in the west of Ireland. Dedicated fell runners can hike all twelve peaks in a single day. Topographically, this range is partnered with the Maumturks range on the other side of the lonely Glen Inagh (and the route of Western Way long distance path). Frequent rainfall and steep-sided mountains produce an abundance of small trickles and streams which descend into wide bottomed valleys below the Twelve Pins to join larger streams with riffles and pools. The Twelve Pins are not exceptionally tall, with the highest peak approximately 730 meters. They provide excellent walking and climbing opportunities for outdoor enthusiasts.
The Irish names of the peaks are commonly used, especially as the English naming has not been stable. (The current anglicised names are given in parentheses.)
