have trouble relying on "two feet or a bike" to get them there

Nah. it's a doddle.
From Blairwood head for Sandwood Bay before reaching the lighthouse -
about 12-13 miles. You'll need a tent or bivvy bag as it will take
most of the day. http://www.rsf.org.uk/routes/capewrath.htm

And there is an easier way for wimps. Call the Ferry at Durness to
reach the rutted 11 mile road to the lighthouse. Allow a day for the
return journey.

That's the route I was thinking about



However, I think you are wrong about the staff as I believe it is no
longer manned and the only visits are those for occasional
maintenance.

Fair point... It's been around 15 years since I was last there
