The youngest volcano in Central America, broken out of a Nicaraguan farm plain in 1850, climbed in 45 minutes and ridden down on a plank.

September·Quiet month

Jun–Sep

The full rains: wet ash packs into a crust, so the sled slows and the climb and rough farm track turn slippery and muddy. Nothing shuts — León operators still run most mornings — and the plain greens up, wettest by September.

Year-round The bare black cone, the hot steam vents in the crater and the plywood board run are there every day; the ride's speed, the heat and the green of the plain all shift with the season.

Cerro Negro is the youngest volcano in Central America, a cone of black cinder 728 metres high that broke out of a farm plain near León in northwestern Nicaragua in 1850 and has erupted more than twenty times since, and it is climbed in forty-five minutes and ridden down on a plank, a sport invented here in 2004 that reaches speeds of 80 kilometres an hour on the ash. The volcano belongs to the Cordillera de los Maribios, a line of cones standing across the plain on the same crack in the crust, seen from the rim one after another, and it behaves strangely for a cinder cone, throwing ash out of the summit crater while its lava breaks out of fractures around the base; its most violent modern eruption, in 1992, reached the city of León twenty-five kilometres away and left it under a grey blanket. The tour vans grind an hour out of León and turn onto a farm track before the cone clears the last rise, black against the green of the plain, and the climb goes up loose scoria that gives back half of every step, with the sled under one arm and the plain shrinking behind. At the rim the crater walls are cooked rust-red, fumaroles vent gas measured at up to 325 degrees, and crouching, the warmth of the ground comes through the palms, proof that a volcano quiet since 1999 is only resting. The ride down is on a plank of plywood with a metal base, sitting, in an orange jumpsuit and goggles, on a slope of 41 degrees, and the speed is measured at the bottom by radar for the bragging; the world record for downhill speed on soil by bicycle was set on this cone, and ended with the bike coming apart under its rider. In the dry season the cinder is loose and fast, and the rain packs it into a crust. Cerro Negro is a volcano younger than the town it covers in ash, and the way down is on a board.

Worth knowing

Good to know

Take the first tour of the day — the black grit bakes by noon, there is no shade anywhere on the cone, and the wind stiffens across the exposed summit through the afternoon.
Keep the goggles on and your heels down — the ash is sharp volcanic glass, and dragging your boots is the only brake the plywood sled gives you.
Book through a León operator — the sled, jumpsuit and park entry all come with the tour, and the volcano sits an hour out of town at the end of a rough farm track.
Vans arrive in waves mid-morning — the first group up rides a smooth face, while later boards find the ash already rutted into grooves by the descents before them.

Things to do

1
Carry a plank up and ride it down
Forty-five minutes up loose scoria that gives back half of every step, with your own sled under your arm and the plain shrinking behind you. On the final ridge the wind arrives all at once, hard and unbroken. Then you zip into a jumpsuit, sit on the plank and push off down the bare cinder face, braking with your heels. It is over in a few minutes, and you reach the bottom black from the goggles down.
2
Feel the heat at the rim of a crater that never cooled
The crater walls are cooked rust-red, and fumaroles vent gas measured at up to 325°C. Crouch and you can feel the warmth of the ground through your palms — proof that a volcano quiet since 1999 is only resting.
3
Trace the Maribios cones from the summit
From the rim, the volcanoes of the Cordillera de los Maribios stand in a line across the plain, each one a separate cone on the same crack in the crust. It is the clearest look you will get at Nicaragua's volcanic spine.
4
Spot the lone cone from the farm track in from León
The tour vans grind an hour out of León and turn onto a rough farm track before the cone finally clears the last rise. Watch for that moment from the window: a bare black heap dropped alone into ploughed, planted fields, with no range and no foothills to soften how out of place it looks. Nothing has taken root on it in 175 years.
