The largest settlement on the Sound isTobermory on Mull, which lies near the northern entrance of the Sound.
There are several ferry routes that use the Sound, most of which originate from Oban. These include the ferry between Oban andCraignure, the main ferry port on Mull, whose main pier was built in 1964.[2][3] Other ferry routes across the Sound include Tobermory toKilchoan andFishnish toLochaline.[3]
