La Palma's beaches are black, steep-sided and often empty, and if you arrive expecting the golden dunes of the eastern islands you will be briefly disappointed and then, usually, won over. This is a young, high, wet island whose coastline is mostly cliff. Sand exists where a ravine has spent a few thousand years grinding basalt down and delivering it to the sea, which means the beaches sit at the bottom of valleys, in small pockets, with green mountains standing directly behind them.

The practical consequence is that La Palma has perhaps a dozen beaches worth the drive rather than fifty, and that they divide neatly. The west coast — the Aridane valley, facing the afternoon sun — has the island's proper swimming beaches with lifeguards, showers and bars behind them. The east coast has one good resort beach and a scatter of wilder ones. The north and the far south are where you go for drama rather than comfort, and the south in particular has beaches that did not exist in their present form before the twentieth century, because the island keeps making new land.

A word on the sand itself, since it surprises people. It is genuinely black, it is coarser than Atlantic quartz sand, and on a clear day in July it gets hot enough to hurt. Flip-flops are not optional. It also does not stick to you the way pale sand does, which is a small mercy, and it holds warmth into the evening, which is why islanders swim late.

Playa de Tazacorte: the island's main beach

If you only have time for one, make it this one. Playa de Tazacorte sits at the mouth of the Barranco de las Angustias, the great ravine that drains the Caldera de Taburiente, and it is the largest easily reached stretch of sand on La Palma. There is a small port beside it, a promenade with restaurants, seasonal lifeguard cover and — importantly on this coast — a breakwater that takes the worst of the swell off the swimming area.

It is also the logical end point of one of the best walks in the archipelago, the descent through the Caldera de Taburiente and out along the barranco. Arriving at the beach on foot, filthy and thirsty, and sitting down to fried fish with the Atlantic in front of you is a genuinely memorable way to end a day. The town proper, up the hill, is covered in our guide to Tazacorte.

Puerto Naos and the gas question

Puerto Naos was, before 2021, the island's closest thing to a resort beach: a long dark strand with a palm-lined promenade, hotels, and the calmest water on the west coast. Then the Cumbre Vieja eruption happened a few kilometres uphill, and the problem that followed was not lava but carbon dioxide, which continued to seep out of the ground long after the lava stopped and which pools invisibly in low, enclosed spaces because it is heavier than air.

The town was evacuated and then reopened in stages, zone by zone, as the readings allowed, with monitoring equipment installed and some areas released before others. That process has been running for years and the situation on the ground changes. Do not plan a week around Puerto Naos on the strength of an old article — including this one. Check the Cabildo de La Palma's own current guidance before you book, and take any posted restriction seriously rather than treating it as bureaucratic caution. Carbon dioxide has no smell and gives no warning.

The rule that matters if you are anywhere in the affected zone: the gas accumulates low down. Cellars, garages, sunken garden beds and swimming pool basins are the hazard, not the open beach. Follow the signage and do not enter a closed area to look at anything.

Charco Verde: the family choice

A few minutes south of Puerto Naos, Playa de Charco Verde — you will see it written as Charco Verde — is a small, dark, sheltered cove tucked into a headland with a little green lagoon behind it that gave it the name. It is the gentlest swimming on this coast for small children, shallow at the entry and largely protected from the west swell by its own rock arms.

Being small, it fills up in August and at weekends, when island families arrive with cool boxes and stay all day. Come mid-morning on a weekday out of season and you may have it more or less to yourself. There is a short, pretty coastal path linking it to neighbouring coves, which is worth the twenty minutes.

Playa de Nogales: the wild one

On the east coast, Playa de Nogales is the beach people photograph: a broad wedge of black sand at the foot of a green amphitheatre of cliffs near Puntallana, reached by a steep zigzag path down from a car park above. The descent takes twenty minutes or so and the climb back takes longer; there is no shade on it and nothing at the bottom — no bar, no shower, no lifeguard.

It is also genuinely dangerous to swim at when there is any swell running. The east coast catches the open Atlantic, the shelving is steep, and the backwash off a black-sand shore is powerful. Local advice is consistent: paddle, admire, and only go in on a flat day and near other people. Our guide to the flag system and Atlantic currents is worth five minutes before you visit any unstaffed beach on this island.

Los Cancajos: the practical east-coast base

Playa de los Cancajos is where a lot of visitors actually stay, because it is ten minutes from the airport and twenty from the capital. The beach is a set of small black coves partly protected by artificial breakwaters, with hotels, dive shops, bars and a promenade behind. It is not the island's prettiest beach and nobody pretends otherwise, but it works: you can swim reliably, eat within a two-minute walk, and be in Santa Cruz de La Palma in time for the evening paseo.

It is also the island's main base for diving, which on La Palma means volcanic architecture — arches, tubes and walls — rather than reefs, and frequently excellent visibility.

The far south: Echentive and La Zamora

Below Fuencaliente, the southern tip of the island is the youngest ground on it, and the beaches reflect that. Playa de Echentive — often called Playa Nueva, the new beach — was created by the San Antonio and Teneguía lava flows reaching the sea; the name is not marketing. It has rock pools filled and emptied by the tide, coarse black sand and almost no facilities.

Playa de la Zamora, a little further round, is a pair of dark coves under a red cliff, reached by a track, with clear water and a bar above in season. Both make a natural pairing with the salt pans at Fuencaliente and the volcano route above them, which is how most people end up there in the first place.

Charco Azul, and why pools beat sand here

In the north-east, Charco Azul is not a beach at all but a set of tidal pools at San Andrés y Sauces, walled and railed and fitted with ladders, so that you can swim in the Atlantic without the Atlantic getting a say in it. On an island with this much cliff and this much swell, that is often the better proposition, and La Palma has a string of them — covered properly in our guide to the island's natural pools.

The combination that locals make, and which visitors rarely think of, is pool plus forest: Charco Azul sits directly below the Los Tilos laurel forest, so you can spend the morning in dripping green shade among tree ferns and the afternoon floating in clear salt water twenty minutes away. Very few places let you do both in a day.

The thing nobody tells you about black sand and swimwear

Here is the detail worth carrying away. Fine black volcanic sand is largely iron-bearing basalt, and it behaves differently from pale sand in two useful ways. It absorbs far more heat, so by early afternoon the dry upper beach can be genuinely painful underfoot — islanders walk on the wet strip or wear sandals to the water's edge and think nothing of it. And it will permanently grey pale swimwear and towels if you let it dry in, so rinse things in fresh water the same day rather than the next morning. Every long-term visitor to La Palma works this out in week one; you can know it before you land.

Getting to them

You need a car. La Palma's buses connect the towns adequately but the beaches sit at the ends of side roads, and the island's geography means a short distance on the map can be a long drive on the ground — crossing from Los Cancajos to Tazacorte means going over or through the central ridge. Allow more time than the distance suggests, and read our notes on driving in the islands if you are not used to steep, narrow, well-surfaced mountain roads with a habit of switching back on themselves.

Sea temperature is the usual Canarian story: swimmable all year, coldest around February and March, warmest in September and October. The west coast is calmer and sunnier in the afternoon; the east coast gets morning sun and more cloud, because the trade winds pile cloud against the island's eastern flank. If a west-coast beach is windy, an east-coast one often is not, and the reverse holds too — it is worth driving across rather than writing the day off.

So, is La Palma a beach holiday?

Not in the sense a Fuerteventura holiday is, and you should know that before booking. There is no long golden strand to spend a fortnight on, the swimming needs more judgement than it does in the south of Tenerife, and the weather on this island is genuinely more variable. If sand is the point of your holiday, our comparison of whether La Palma suits you says so plainly.

What La Palma offers instead is a beach at the end of a walk, a tidal pool below a laurel forest, and an empty black cove where the only sound is the swell dragging on gravel. Base yourself near Tazacorte for swimming and sunset, keep the southern beaches for a day that also takes in the volcanoes, and treat the wilder east coast as scenery you occasionally get into. For the other islands' coastlines, our roundups of Tenerife's beaches and the beaches of neighbouring La Gomera make the contrast clear.
