Formentera with children, at an easy pace.

Why the island suits families

Formentera runs about 19 km end to end and covers roughly 83 km², which changes how a family day works. A beach in the morning, a village at lunch and a lighthouse in the late afternoon all sit comfortably within range. Outside the busiest weeks of July and August the roads feel quiet, the signposted green routes are shared rather than crowded, and no one spends the day strapped into a car seat.

The water is the reason most families come back. Several beaches shelve so gradually that a small child can stand well out from the sand, and the sea stays warm enough for long sessions. Typical sea temperatures are about 22-23 °C in June, 25-26 °C in August and 23-25 °C in September. Those are averages rather than forecasts, but they explain why mornings on the sand stretch into lunch. Wind on the Migjorn side can make the water feel cooler.

The water is the reason most families come back, and it stays shallow a long way out.

Getting there from Ibiza

Formentera has no airport, so the journey is a flight to Ibiza (IBZ) and then a ferry from Ibiza Town port to La Savina. Fast ferries take about 30-35 minutes and conventional ferries around an hour. Sailings are frequent in season and fewer in winter; check the operators for current timetables. With children, the crossing is short enough to count as part of the day rather than a trial.

La Savina is the arrival point, with the ferry quays, the bus stop and bicycle hire close together, so the transfer to a base is short. From the port the road runs east along the island towards Es Pujols and Sant Ferran. If you arrive with luggage and tired children, staying close to the port for the first night removes the pressure of a connection. Ferries in high summer fill, so book ahead and check the operator's rules on luggage and bicycles.

A base at Es Pujols

Es Pujols sits on the north side of the island and works well as a base with children: a village beach, a short walk to most of what a family needs, and roads that lead easily to Ses Illetes and the lagoon of Estany Pudent. The water off the village beach is shallow and the sand is close to the streets, so a quick swim before lunch takes no planning. The village is seasonal, and much of it closes from roughly November to April.

Other bases suit different families. Sant Francesc Xavier, the capital, keeps island life going year-round, with the fortified 18th-century church built as a refuge at its centre. Sant Ferran de ses Roques is a small, lived-in village nearby. Cala Saona and the Migjorn coast are quieter and more remote, which works well until you need a shop for a forgotten pair of sandals or a pharmacy.

Beaches that suit small swimmers

The island's beaches differ more than a small island suggests. The north and the Ses Illetes strip have calm, shallow water held by sandbars and the protection of the natural park. The south, along Platja de Migjorn, is longer and more open, with stretches of flat rock between sandy entries. Cala Saona on the west is a compact cove. For a first morning with small children, pick a beach where the entry is sand rather than rock and the wind is offshore.

Posidonia meadows do two useful things for families: they keep the water clear and they soften the swell before it reaches the shore, which is part of why the shallows are so calm. The leaves that wash up as brown banks on the sand are part of the same system. They look untidy and are not; they hold the beach together and feed the food chain offshore. Explain that once and children tend to leave them alone.

• Ses IlletesVery shallow water, sand underfoot and the natural park around it; go early in the day.
• Cala SaonaA small west-facing cove with a sandy entry and a sunset; check the swell before committing an afternoon.
• Platja de MigjornLong and open; walk until you find a sand entry rather than a rock shelf, and mind the wind.
• Es PujolsThe village beach, shallow and central, and easiest before the middle of the day.

Getting around without a car

The island is flat enough that bicycles do much of the work. Signposted green routes, the circuits verds, link the villages, the beaches and the salt flats, and they keep families off the main road. Hire shops in the villages have child seats, tagalongs and trailers; ask about the fit before you ride away. Distances are short, but the middle of a July day is not the moment for a long ride.

Buses link La Savina, the villages and several beaches, with more services in summer and fewer out of season; check the island bus operator for current routes and times. Taxis are limited, and a small island has a small fleet. Bringing a car is possible and sometimes sensible with very young children, but the Consell de Formentera caps visitor vehicles in high season, so the rules change from year to year.

A beach day that works

The rhythm that suits most families here is early water, a long lunch, shade through the middle of the day and a return to the sand in the late afternoon. The sun is strong from late morning, and a breeze on the open beaches hides how quickly it burns. Shade is not guaranteed on the sand: some beaches have none at all, so carry your own or plan around the rocks and the pines.

Pack for a small island: water, hats, sun cream, something to sit on. Shops exist in Es Pujols, Sant Ferran and Sant Francesc, but a beach two coves along may have nothing at all. Footwear matters more than it sounds, because some entries are rock shelves and posidonia banks rather than sand. Take everything back with you, including the things that seem small.

• WaterCarry more than seems necessary and refill in the villages rather than relying on the beach.
• ShadeA lightweight shelter or an umbrella, because several beaches offer no natural shade at all.
• FootwearSandals that stay on in the water, for rocky entries and the walk between coves.
• RubbishTake it back to the village; bins are not placed on the remoter stretches of sand.

Food and small appetites

Village life supplies the practical side of eating. Sant Francesc Xavier has the widest choice of shops and bakeries, with Sant Ferran and Es Pujols close behind in season. Kitchens often open later than families with young children are used to, so a late-afternoon snack and a later dinner is a common pattern. Many restaurants close from roughly November to April, and outside the main villages the options thin out quickly.

Local food is simple and useful for children: bread, tomatoes, olives, cheese, grilled fish, and the dried fish, peix sec, that has been made here for centuries. The market at El Pilar on the Mola is worth a morning for fruit and picnic supplies; check the day before you go, as the pattern can change. Bakeries sell out early. A picnic assembled in the morning solves lunch on a remote beach.

Posidonia, lizards and lagoons

The clear water is a plant's work. Posidonia oceanica is a flowering seagrass found only in the Mediterranean, and its meadows run from the shallows to about 30-40 m deep. Anchoring over them is regulated by a Balearic decree, and mooring buoys are installed in some bays in summer. From the surface, the dark patches are the meadows; the pale sand channels between them are where an anchor goes.

Two lagoons, Estany Pudent and Estany des Peix, sit inside the Ses Salines Natural Park and draw birds through the year, which makes a slow hour with binoculars worthwhile. The Pitiusan wall lizard lives only on Ibiza, Formentera and their islets, and turns up on walls and rocks. It is quick, harmless and best left unfed. Ca na Costa, a megalithic tomb near Es Pujols, is about 4,000 years old and needs only a short stop.

• PosidoniaDo not anchor on the dark patches; use a buoy where one is provided or anchor over sand.
• LizardWatch it on walls and rocks and keep snacks out of reach; it is endemic to these islands.
• LagoonsEstany Pudent and Estany des Peix are best early, when birds are feeding and the light is flat.
• Ca na CostaThe megalithic tomb near Es Pujols takes minutes to see and shows how long people have lived here.

Out of season and quieter weeks

From roughly November to April many hotels, beach bars, boat trips and seasonal buses stop, and some restaurants close with them. Sant Francesc stays open year-round, as do the ferries, in reduced numbers. Winter here is quiet rather than empty, and the sea is cold: about 14-15 °C in February and March. A family with young children will find more closed than open, and should plan around the villages rather than the beaches.

June and September are the sweet spot for most families: warm sea, fewer people than August, and businesses open. The Balearic sustainable tourism tax, often called the ecotasa, is charged per person per night by the accommodation; the rate depends on the type and category of accommodation and the season, children under 16 are exempt, and rates change, so check the Govern de les Illes Balears. Flexible bookings and a plan for a wet or windy day help at the edges of the season.
