Ermita del Santo Angel de la Guarda to Guía de Isora

10.4 km by bus. 14 km walking.

Catch the 462 bus to Los Gigantes from Guia de Isora bus station.
Get off at the Ermita del Santo Angel de la Guarda a little south of Las Manchas.
Walk south downhill along the TF-375 for 130 metres.
Turn left onto a footpath, SE.
This soon joins a wider track, NE, uphill.
Follow this path NE for a long stretch, about 1.4 km.
Don't take the right turn, east, about 1 km up this path.
The correct but less visible path heads north and soon NE again.
Cross a wide lava flow, yet to be colonised by many plants.
Finally at trees, turn right, uphill, east, for just 25 metres.
Emerge on a wide 4x4 track and turn right, south.
This 4 or 5 km road is almost level by Tenerife standards.
At the TF-38 main road, head SE along the road for 330 metres.
Take second left, east and soon nearly north.
The road swings right, soon SE again.
The recorded track disobeys the hobbit rule. "Never Leave The Path".
Instead of the second left, I took the first left and went off-piste for 200 metres.
This saved 150 metres of horrible tarmac and the terrain was not too rugged.
If you try this, rejoin the correct trail up a steep bank.
There is a safe path up, a few metres east, up the valley.
Follow the 4x4 trail south and SE. Ignore the trail heading east.
Eventually the trail reaches a galería or water mine.
There are railway tracks used to shift spoil out of the tunnel.
Head for the pipes and then downhill, east and right, SW and later south.
After 170 metres on the narrower 4x4 track, turn left, SE, on a little used footpath.
Follow the path, marked by rows of stones along its edges.
The path stays close to the pipes almost all the way back to the TF-38.
There are a couple of places where the pipe drops too steeply for the path.
Pay attention and zigzag down on the stone lined trail.
This little used path is covered in pine needles and fir cones so it's harder to follow.
Cross the TF-38 and head roughly south on a better path.
Ignore paths left and right and continue mainly south, following the pipes.
Cross the TF-38 again. On concrete head down and soon head south along the pipes.
Briefly head left away from the pipes avoiding a steep overgrown stretch.
At a junction, turn right and soon rejoin the pipes, SW.
Don't take the way-marked path, right, west. Continue along the pipes, SW.
This leg is a little overgrown but passable. Look out for long thorny trip hazards.
At tarmac, turn right along the road and immediately left, south, following the pipes.
The path bends SW and comes out on a wide stone and concrete road near the water works.
Continue SW and join the main road down into Guia de Isora.
Head past the water works with more pipes than you'll have ever seen.
Head SW into town and then SE back to the bus station.
