Come to think about it, i was pretty impressed with my circumnavigation around the entire island of Barra, in the Outer Hebrides.
There was a road running around its entire circumference, a distance of just a little over thirteen miles, which i followed from start to finish.
The inhabitants were extremely friendly, and even though the island has a very small population, and beaches to rival any in the Mediterranean, it had a fairly hilly topography, ideal for a weeks adventure.
The thing i really liked about the island, was its back to the 1960s atmosphere, nobody was in a hurry, and a very peaceful existence.
