When coming from Pakhuys, drive past Traveller Rest's Farmstall. After approx 400 meters turn right.
Drive past the cattle gate, and take the first road to the left. Drive the road for 2.3km and you'll reach the end of the road. Park the car so that you don't block farmers/other climbers.
The path goes South, which means to the right from the direction you came from. Follow the cairned path for 500 meters and you'll arrive to the Last Boy Scout -boulder.
From that the Inevitable is 200 meters to the right.
