Skye remains magnificent, even after so many people have said it. Getting there via the A87 is a blast (motorcycle heaven, alas literally on occasion). Pop over the hill to Glenelg (via stunning views of the five sisters mountains) on the way for a fine bar lunch in the local inn (sit out and enjoy the views). There is a ferry crossing from here to Skye in the summer months.
Traverse Skye (up the right hand and over to Uig), and take the ferry to Harris. Harris is a joy to behold; arrive by bicycle and head south after taking in the beaches on the west of Harris itself. Get the right weather and it is wonderful; I say this having travelled from the north of Japan to the south of Chile and too many points in between to recall; South Africa and the Rockies match the Scottish Highlands for sheer natural beauty, but in neither can you venture out on a clear night in midsummer to catch the elusive haggis.
Avoid John O’Groats and most other stuff east of Tongue, unless you have to seek refuge from hellish weather (always possible, any time), in which case use Dornoch as a base for touring.
Best beaches are Oldshoremore (sublime) out west from Kinlochbervie and the incomparable Sandwood bay if you have the energy for the hike. Please leave both as you found them.
Ullapool is now touristy but still charming: small, compact, good bookshop, plenty of places to eat/drink; an ideal base.
From there head north to Lochinver via the coast road and again north to Scourie via the coast road (Drumbeg etc).
Late May early June to avoid the worst of the midges (do not underestimate the blighters).
