An alternative route

In many ways Cape Wrath isn't really the finish line for anyone walking there - arriving at the most North-Westerly tip of Britain, suddenly you'll realise you have to get home, which could take a couple of days unless you're a logistical genius.  

Regardless, instead of walking the road back to the ferry or taking the minibus, one could do this:

The startpoint is Strathchailleach bothy, and after reaching the cape, the hills climbed are Sgribhis-Bheinn (371m), Fashven (460m) and Ben Akie (288m), totalling 20 miles and 1300m of ascent - a long way but not that much ascent really - we'll see if I do this come end of August...

This is the best bit of the map:
