Guia de Isora to Chio, then NE to a Galeria and back to Aripe

From the Calle Campo bus stop, head west and drop down to the main road TF-82. Head NW along the main road. Use a quieter parallel side road for 250 metres. Continue for another 330 metres, then turn left, NW, on a farm access road. Follow this road NW all the way to Chio. Head into town and uphill. Turn right along Calle el Atajo, NE. Turn left, north, up Calle la Redonda. Turn right, NE, along Calle Madrid. Cross the main road, TF-82, and head uphill, roughly east, along Calle Pinito. The tarmac ends and a gravel path continues. Cross the TF-38 with a right left kink and head up more tarmac, east then NE. The tarmac ends and the road becomes gravel. Continue uphill NE. Cross the canal. The path zigzags a bit. Continue NE. Eventually you reach a wider forestry road, the Pista de Fife. Turn right and very soon left up a way-marked footpath with stones marking its edges. Follow this path, NE, all the way to the TF-38, crossing the forestry road twice more. Cross the TF-38 and head east, still on a good path. Cross a forestry road and continue east to signposts. Turn right, south, downhill, perversely the only direction not signposted. The path is small but well laid out. Soon it joins a road. Head SE to the water mine, in Spanish, a galeria. You can see the railway line used to remove the spoil and there is a tunnel with a large pipe carrying out the water. Google says there are around a thousand of these in Tenerife and 4000 km of tunnels. From the galeria, head SW on a narrower road. Look for a left turn, south, back onto a small stone lined path. It's easy to miss this turn. Stay close to the pipes. If you miss it, you'll end up having to walk down the TF-38. OK but less nice. Continue south, ignoring a crossing path. Stay close to the pipes but look for the lines of stones marking the path, especially if the terrain seems to be getting difficult. You may need to backtrack to the correct path. Re-cross the TF-38 and continue down, SW and south, still following the pipes. Ignore crossing paths and continue south. Cross the TF-38 a final time and continue south, still following pipes. The path bares left away from the pipes avoiding a passable but overgrown section. Later the path bends right to rejoin the pipes. At the pipes and junction, head south down to Aripe. This was the hardest bit of the walk with loose gravel on a steep path for 350 metres. There is an alternative way down, following the pipes of course. The steep path joins the tarmac. Head downhill back to Guia de Isora. The track follows Calle Villanueva for a change. This is not the shortest route to the bus stop.
