This unpaved path (gravel) offers an unobstructed, almost dreamy view of Mount Errigal's iconic cone shape. Directly in front of you, Mount Errigal's (751m) striking, light-grey quartzite peak rises from the surrounding peat bog. The dreamy atmosphere is enhanced by the vast, empty valleys that surround this path.

A charming townland on Donegal's Atlantic coast, An Bun Beag (often Anglicised to Bunbeg) has much to offer the walker.
