Steep and hair-raising, the GC 210 road drops from the pine-shrouded cumbres right down to the west coast town of La Aldea de San Nicolas. It's the kind of the road that fries brake pads and makes grown men cry (we've seen it happen).
But wow, is it spectacular.
GC 210 starts between Cruz de Tejeda and Tejeda on the GC 60. First you drive through Artenara, Gran Canaria's highest village: Stop for views of the island's central caldera and its iconic rocks. Further on the road drops steeply in a series of hair pin bends and get glimpses of the cave village of Acusa Seca (look behind you) and the emerald green Presa de Parralillo reservoir.
The most famous viewpoint here is by the renovated old windmill: A great spot for the photos without having to stop in the road.
This is Gran Canaria at its wildest with huge masses of volcanic rock cleaved by deep ravines. Nobody has lived here since pre-Hispanic times apart from a few goatherds.
The GC 60 links up with the GC 606 that takes you back up to the main road, but it's a steep old climb with huge drop-offs and no barriers.
Otherwise, you come out in La Aldea and have to choose between going north or south along another lunatic road: The GC 200. North takes you along the cliff edge route up the west coast to Agaete and south heads inland through the steep Degollada de Tasarte back to the south.
