Guinness outside The Boathouse on the island of Ulva.

We stayed in a wonderful farm house on Mull near the Ulva ferry.
The small island of Ulva (pop about 10) proved excellent walking territory, with well marked tracks, old farms, a Telford church and links to both David Livingstone and Lachlan MacQuarie, first Governor General of New South Wales ("Father of Australia").

Here is a website for Ulva.
