The A9 is the main route in and out of Caithness and hugs the north east coast all the way from just north of Inverness to just south of Wick where it turns inland at the village of Latheron Wheel and traverses the so-called flow country (vast peat moorlands of Caithness) for the last 15 miles up to Thurso.
From Thurso you take the road east towards Castletown and John O'Groats. You then take the last turning for Scarfskerry on the left (if you go though the village of Mey you've gone too far). Go down this track towards the sea. After a mile or so at the sign which says 'Hoy View B&B' take the right turn and go as far as the track allows. Mey Cliff Cottage is on the left on the cliff edge.
The journey from Inverness to Mey Cliff Cottage takes about 2.5 to 3 hours. You can also take a coach from Inverness to Wick/Thurso and then a connecting bus to Scarfskerry/Mey with local bus company Rapsons or even hire a car in Wick/Thurso.
Consult Google Maps for a route from your start point if you intend to drive.

There are some railway stations literally in the middle of nowhere!
You can time your connection from Inverness with the trains from the South. There are direct trains to/from London Kings Cross during the day. These trains follow the main east coast line taking in Edinburgh, Newcastle, York and Peterborough on their journey to/from the capital.
