Shortly after breakfast, two blue coaches pulled up to the boat to take us on our morning outings. One group ventured off with Robin and Eric into the heart of the Cuillin Mountains on the Isle of Skye. The Cuillin Mountains are volcanic and they were formed over 60 million years ago. The Black Cuillins are made of dark volcanic gabbro and the Red Cuillins are made of rusty-red granite. Our path went between the Black and the Red peaks, traveling up the Sligachan Valley. Bright yellow bog asphodel, lavender bell heather, and white cottongrass splashed color across the valley. A few sundews grew along the trail, an insectivorous plant that can make a hearty meal of the midges that accompanied us for part of the walk.
