Bayuyo is the summit of an extinct volcano near Corralejo, so near that it is possible to walk from the town out to it.
Getting there passes through some of the ghostburbs so if you examine the route you can see that it passes along the south of a rectangular layout of roads labelled Tres Islas. In fact as of 2015 all that is there are roads, with bare earth and the odd desert plant in between. Disastrous as the property crash in Ireland is, you have to see what it has done to Spain, the Canaries in particular, to appreciate how destructive these can be.
The actual walk goes through what appears to be a semi-active quarry/builders yard. We saw other walkers there however in future and if the local economy picks up I would anticipate that future walkers would need to pick a different route, for example following the GR131 walking route initially.
As is usual with volcanoes, one side, in this case NE facing, has collapsed so that the land forms a crescent. We walked around this.
The view on the day we did it was tremendous. Bayuyo is one end of a chain of volcanoes stretching SW which are very visible from the top as is the northern coastline of Fuerteventura and much of Lanzarote.
