Full description
Thirteen tunnels and a water channel
Seven hours and twelve kilometres above San Andrés y Sauces, on the green side of La Palma. The walk follows the lip of a channel cut into the mountain about a hundred years ago to bring water down to the villages and to turn it into electricity, and where the rock got in the way the men who built it went through it. Thirteen of those tunnels are on this route, and the longest is four hundred metres.
How the day runs
The group meets by the wooden hut in the Los Tilos car park at 9:30 on a Thursday. From there a 4x4 taxi climbs fifty-five minutes of mountain track to the Casa del Monte, the house built for the men who cut the channel, and the walking starts at the door.
Then it is about two and a half hours and five kilometres beside the water, in and out of the rock. A helmet, a head torch and a poncho are handed out before you set off, and all three get used: the tunnels are unlit, several of them drip, and the twelfth soaks your shoes through. Bring sandals that strap to your foot to change into, or at least spare socks.
The tunnels end at the Marcos y Cordero springs, the best known water sources on the island. From there it is downhill on foot, about three and a half hours and seven kilometres through laurisilva, back to the car park at Los Tilos where you left the car.
What the route crosses
The channel runs along the side of a ravine system, so the drop beside the path is real and the far walls are a long way up. On the way the route cuts through several dikes, the sheets of volcanic rock left standing where magma forced its way up through a crack and cooled harder than everything around it. Because the water never stops, the laurel forest along the channel grows thick the whole way.
Worth knowing
It is graded hard: only 200 m of climb, but 1,100 m of descent over the day, so trekking poles help. Four people is the minimum for the 4x4 to run. Take at least a litre and a half of water each, something to eat, a jacket and something for rain. Sections of the path close now and then after bad weather or rockfalls. Dogs cannot come on this one.
