Most visitors arrive by the main Oban - Mull ferry, which runs every couple of hours during the summer months, and everyday during the winter with a slightly reduced timetable. The crossing is about 45 minutes. It is advisable to book your car in advance.
Another option is the ferry from Lochaline (on Morvern) to Fishnish (on Mull). This ferry crossing takes about 20 minutes, and is a lot cheaper that the Oban crossing. It works on a first come/first serve basis, but you have further to drive and you also need to use the Corran Ferry. This crossing is of benefit if you are travelling from the Fort William area.
If you are travelling from Mallaig or Ardnamurchan, then the ferry crossing from Kilchoan (on Ardnamurchan) would be your best bet. This takes you to Tobermory (on Mull). This ferry is non bookable.
