I used to love the drive up through Glencoe to Fort William then across Ardnamurchan Peninsula through Strontian to Lochaline then take the small ferry across to Mull, beautiful scenery, great roads and lovely places to stop. My recommendation for the Islands is Mull, southern Mull to Fionnphort is lovely and if feeling intrepid the walk to the fossil tree on the Burg is spectacular. If you have good sea legs a trip to the Island of Staffa and Fingal's Cave is worth doing too, load Mendelssohn's Hebrides Overture on your phone and play it whilst watching the waves crash into the cave.
