La Geria: vines growing in volcanic ash, one plant to a pit

Everything about this landscape is an answer to one problem: there is very little rain here, and there is a great deal of wind. Ordinary farming answers that with irrigation. This island answered it with the material the eruptions left on the ground.

The hollow. The grit covering this ground is deep, loose and dark. Dig a shallow bowl in it, plant a single vine at the bottom, and two things happen at once. The plant sits below the level of the wind, and its roots reach down through the loose material to what lies beneath. The pit is not decoration; it is depth.

The wall. Around the upwind rim of each hollow sits a low arc of dry-stacked stone. It is a half circle rather than a full one because the wind here has a direction, and there is no point spending stones on the sheltered side. Seen from a moving car the whole slope looks like a field of dark craters with a lip on one edge of each — and once somebody points out which way the lips face, you can read the prevailing wind off the landscape.

The grit itself. Fine dark material takes up moisture from the night air and releases it downwards, and it also caps the ground so that what is underneath does not dry out in the sun. That is why the vines survive a season that would kill them on bare rock, and it is the reason the ash is farmed rather than cleared. La Geria Lanzarote vineyards volcano country produced is the visible result: agriculture built directly out of what fell from the sky.

The spacing. Because each plant needs its own hollow and its own wall, the vines sit far apart. The yield per hectare is low and the work is done by hand, and those two facts explain more about the price of the wine than anything on a label does.

We are not going to tell you that a tour includes a vineyard stop when its own listing does not. Here is the position as it stands on the twenty-two listings on this site.

No title names it. The titles on this site name the park, the caves, El Golfo, the island highlights, the south, Fuerteventura and the sea. None of them names La Geria. That does not mean no route passes through the wine country — it means the title is not where you find out.

The itinerary is where it lives. Full-day tours are sold on a list of stops, and that list is printed on the listing page, stop by stop, before you pay. $58 is the nine-hour island day with the strongest rating here, 4.7 across 3,303 reviews, and its own page states what is on its route. Read it for the date you want.

What the shorter days are for. $68 at five hours and $68 at six are built around the park and the volcanic south. Some southern routes pass through this landscape on the way; again, the itinerary is the place that says so.

And the long pairings. $100 at eight hours and $102 at nine spend their day between the park and the north of the island, which is a different axis across the map from the wine country.

For the widest route across the island, book $58. Nine hours, rated 4.7 across 3,303 reviews, with its stops printed on its own listing.

For a shorter day centred on the park, book $68. Five hours, rated 4.4 across 2,785 reviews.

For six hours across the park and the south, book $68. Rated 4.4 across 1,019 reviews.

For the park plus the north, book $100 at eight hours or $102 at nine, rated 4.5 across 2,050 and 2,845 reviews respectively.

And for volcanic ground under your own steering, book $172. Two to three guided off-road hours, rated 4.7 across 5,513 reviews.
