You can't visit the white village of San Pedro, about half way up the Agaete Valley, without looking up: it's right under the highest cliffs in the Barranco and looks more like an alpine village than a Canarian one.

 Tiny Carrizal de Tejeda is Gran Canaria's Masca hamlet but without its Tenerife twin's souvenir shops and coach queues. 

The only access, unless you hike or bike in, is via the tortuous GC-606 road between the Cumbres and La Aldea. It's narrow, windy and barrier-free in parts but well worth the effort.

There's not much to do in Carrizal de Tejeda except wander about and enjoy the tranquility. Have a drink at the bar and enjoy the view from its rooftop terrace. 

Stop at the viewpoint just above the hamlet for a bird's eye view of Gran Canaria's least known volcanic monolith: Roque Palmes is a stunning mini Roque Nublo sitting right in the middle of a steep gorge.
