Oban is a resort town within the Argyll and Bute council area of Scotland. Despite its small size, it is the largest town between Helensburgh and Fort William. During the tourist season, the town can have a temporary population of up to over 24,000 people. Oban occupies a setting in the Firth of Lorn. The bay forms a near perfect horseshoe, protected by the island of Kerrera; and beyond Kerrera, the Isle of Mull.
