Along the shores around Camas Choire Mhuilinn to the east of Mingary Castle, there are some exceptions. These fine trees are miles from any human habitation, yet they face almost straight into the prevailing, salt-laden winds, the soil can't be either particularly deep or rich, and they back up against a steep cliff. But look carefully - there's a very old stone wall running diagonally up from the beach, so perhaps the people who built it had something to do with their nurture.
All these pictures were taken along the section of shoreline to the east of Mingary Castle in July. There's a map of the area here.
