Volcano Hikes on Lanzarote: Walking the 1730 Lava Fields

Timanfaya National Park covers a little over fifty square kilometres and the visitable core of it, the Montañas del Fuego, works like a museum with a one-way system. You buy a timed ticket, you are driven to the Islote de Hilario, you get on a coach, and the coach does a fourteen kilometre circuit in about thirty-five minutes without stopping. Between the entrance and the car park you are required to stay in the vehicle. The park's own wording is unambiguous: it is not permitted to travel through it freely on foot or by car.

The lava field, however, does not stop at the boundary. The 1730 to 1736 eruptions buried roughly two hundred square kilometres of Lanzarote, and a large part of that sits outside the national park inside the Parque Natural de Los Volcanes, which has no such restriction. Every commercial walk on this page happens there. The cones you climb, Pico Partido, the Caldera de la Rilla, Montaña Señalo, Montaña de las Nueces, all erupted in the same event as the ones you photograph through a coach window.

If a listing promises a hike inside Timanfaya National Park, it is describing something the park does not allow. What it is actually selling is usually better: the same rock, on foot, without a coach.

This is the part worth writing down. The national park runs guided walks on foot, inside the boundary, in English as well as Spanish, and they cost nothing. The Ruta de Tremesana starts near Yaiza and covers about three kilometres over roughly three hours, on weekday mornings. A second guided route runs along the coastal side from El Golfo, about 2.8 kilometres and again around three hours.

The catch is arithmetic. Each departure takes eight people. There is a minimum age of sixteen, closed shoes are compulsory, you need identity documents matching the booking, and you are told to arrive fifteen minutes early or lose the place. Booking opens about a month ahead and it is done through the national park reservation system, not through the same website that sells the thirty euro Montañas del Fuego ticket. That split is why so few visitors ever find these walks: people look on the ticket site, see no walking option, and conclude there isn't one.

There is also a longer route along the coast, roughly nine kilometres, that can be walked without a guide and without booking anything. It is not a stroll. The surface is malpaís, broken lava that turns an ankle if you stop paying attention, there is no shade and no water, and it takes considerably longer than nine flat kilometres would suggest. Take more water than you think and start early.

Three of the six are genuine walks. Two are coach outings with the word volcano in the title. One is a buggy. Sorting them takes about thirty seconds if you look at the duration and the meeting point rather than the name.

The three real walks cost between forty-two and forty-four euros, run three to four hours, take small groups, and two of them include pickup from the resorts and water. Two are rated 4.9 across more than six hundred reviews between them, which in this catalogue is unusual. They are the best value in Lanzarote volcano tourism by a wide margin, and the reason is not mysterious: no entrance fee is being resold to you, so the price is the guide.

The 59 EUR coach trip is a decent way to see the park, and it is honest about what it is. Read one detail in its own conditions, though: if the national park closes, and it does close for wind, the trip visits the interpretation centre instead. That is a sensible fallback and a completely different afternoon. The 130 EUR half day and the 200 EUR buggy both do things worth doing, but neither is a hike, and if walking on lava is the point, the 42 EUR option delivers more of it for a fifth of the price.

One crater is worth knowing about even if you book nothing at all. The Caldera de los Cuervos, reached from a small car park on the LZ-56, is the cone people walk into: one of the operators here builds a forty minute loop around it into a longer trip. It was the first vent to open in 1730, and you can stand inside it without a ticket, a guide or a booking.

Four things decide whether this is enjoyable, and none of them is fitness. Shoes that cover the ankle, because lapilli is coarse volcanic grit that fills a low shoe within a few steps and then grinds. There is no shade anywhere on this lava, none at all, so a hat is not optional between May and September. There is no water either, on any of these routes, and no shop to buy it from. And the trade wind blows most days, which is the reason Lanzarote's temperature is pleasant and also the reason a windproof layer belongs in the bag even in August.

One operator adds a line the others leave out: not recommended for travellers with poor cardiovascular health. That is a fair warning for a four hour walk on uneven black ground in the sun, and it is more useful than the standard reassurance that a trip suits all fitness levels.

There is no season to plan around. These walks run all year, the island's temperature moves little, and what changes is the time of day rather than the month: the surface reflects heat back at you from about eleven, and the light for photographs is better before that anyway. Book the early departure.
