Crag published in spanish climbing magazine Desnivel. In a La Palma article is a map with crags of La Palma und Nambroque is there with no further information. In another Climbing magazine are climbing pictures with good rock and bolts of Nambroque.
Location unknown, if you know or find out more, please contribute here, thx!
It's not the summit cliffs of Pico Nambroque, I checked it out by scary scrambling around, they are not worth climbing. If there is really climbing, it should be somewhere else... Nice hike anyway!
At (28.598591,-17.780794) a road goes up with road sign 'Nambroque'.
