Some days in Ibiza, you wake up and the island feels like it is quietly pointing somewhere else. The first April light slides across the bougainvillea, the Mediterranean out past the port is doing that impossible turquoise thing it does, and you realise: today is a Formentera day.
Formentera is Ibiza's smaller, wilder sister — a thirty-minute ferry ride across a channel so clear you can often see the seabed from the top deck. It is the southernmost of the Balearic Islands, a sliver of sand, salt and juniper roughly eighty-three square kilometres in size, and it is, quite simply, one of the most beautiful places in the Mediterranean. If you only have one day to escape the rhythm of Ibiza, make it a Formentera day trip. Here is exactly how to do it right.
Why Formentera is the perfect day trip from Ibiza
The short answer: because Formentera is what the Balearics looked like before the world found them. No high-rises, no traffic lights, almost no big-brand hotels. The island has fewer than 13,000 year-round residents and a strict planning code that has kept its whitewashed fincas, low stone walls and posidonia-clean bays more or less intact for fifty years.
The posidonia is the secret, by the way. Those underwater meadows of seagrass — designated a UNESCO World Heritage site in 1999 — are what give Formentera's water its almost unreal transparency. They filter the sea, stabilise the sandbanks and turn every cove into a natural swimming pool. You do not need a filter on your phone when you are floating over posidonia.
Add in world-class beaches (we will get to those), some of the best grilled fish on the Mediterranean, a cycling-and-walking culture that makes the whole island feel like one long outdoor gallery, and the sort of sunsets that make you forget to check your phone, and you have the perfect day trip from Ibiza.
Getting there: ferries, timings and practical tips
You leave from Ibiza Town's main port, Estació Marítima. Three operators — Balearia, Trasmapi and Aquabus — run fast ferries to La Savina, Formentera's only port, more or less every thirty minutes from morning until evening during the warm months.
A few things worth knowing before you book:
- Journey time: 25 to 35 minutes depending on the operator. The newer boats are faster but also a touch pricier.
- Cost: Expect €35 to €50 return in shoulder season (April, May, October), rising steeply in July and August. Booking online in advance is usually cheaper than the port kiosks.
- Best time to leave: Catch a ferry between 9:00 and 10:00 to get a full day on the island. Aim to return on the 18:30 or 19:30 — anything later and you will be eating dinner at midnight back in Ibiza.
- What to bring: Water, strong sunscreen, a sarong or light layer, swimwear under your clothes, cash for chiringuito lunches, a small backpack. Reef shoes are handy for rockier coves.
If you can, sit on the upper deck on the way out. The approach past Es Vedrà on your right and the little island of Espalmador on your left is the sort of boat ride that feels like a film sequence.
Getting around once you arrive
Formentera is long and thin, about nineteen kilometres from one tip to the other, and it is absolutely not a place to try and walk. You have three real options:
- Scooter: The classic choice. Rental shops line the port at La Savina; expect €25 to €40 a day depending on engine size. You will want an EU-recognised driving licence and a bit of road confidence.
- Bicycle, ideally electric: Formentera is genuinely flat and cycle-friendly, with a network of well-signed "green routes" running between beaches, villages and viewpoints. An e-bike opens up the whole island without the sweat.
- Car: Possible, but overkill for most day-trippers, and parking at beaches like Ses Illetes is a lottery in peak season.
My strong suggestion for first-timers: rent an e-bike. You will see more, you will move slower, and you will feel the island properly.
The beaches worth planning your day around
You could spend a week on Formentera's beaches and still not see them all. For a day trip, pick two — one for the morning, one for the late afternoon — and leave time for a slow lunch in between.
Ses Illetes is the one that launches a thousand postcards. A narrow spit of white sand on the north of the island, with the sea hugging it on both sides, it is consistently ranked among the best beaches in Europe, and with good reason. Go in the morning, before the yacht crowd floats over from Ibiza.
Platja de Migjorn, on the south coast, is six kilometres of pine-backed sand broken up by rocky coves. It is where locals actually swim. The central section near Es Arenals is the most accessible; head further west toward Es Ca Marí for quieter pockets.
Cala Saona is the classic photograph — terracotta cliffs, flat turquoise water, a single low-rise chiringuito, and Es Vedrà glowing on the horizon at sunset. If you only have time for one cove, make it this one.
Es Caló des Mort is the hidden-gem choice: a tiny sheltered beach on the south-east coast, tucked below the old fishermen's huts. You walk down a steep stone path to reach it, and the payoff is extraordinary.
Eat like a Formenterer (not like a tourist)
A Formentera day without a proper lunch is a day half-lived. The island's food scene is defined by two things: simplicity and an obsession with freshness. The fish was caught this morning. The tomatoes were grown in the sandy plots up the road. The local ensaïmada came out of the oven before you did.
A few places that will not disappoint:
- Can Carlos, near Sant Francesc, hidden in an old finca and serving thoughtful modern-Mediterranean cooking in a garden setting.
- Es Molí de Sal, on the edge of the salt flats: the view is the reason to come, but the grilled fish and rice dishes more than earn their place.
- Beso Beach, on Ses Illetes: glamorous beach-club atmosphere, paella worth the price tag, and one of the best ends-of-the-world lunch tables in the Balearics.
- Chiringuito Bartolo, on Migjorn: old-school, family-run, plastic chairs in the sand, and the kind of fresh grilled sardines that stay with you for years.
If you do one thing food-wise: order a bullit de peix — the islands' signature rice-and-fish stew, served in two courses. Call ahead the day before if you can; it is slow food in the best sense.
Sunset, the salt flats and getting back to Ibiza
If you time it right, end your day at the salt flats of Ses Salines de Formentera in the north, or at the lighthouse of Cap de Barbaria in the south. Both are, in different ways, among the most cinematic sunsets in the Balearics. The salt pans glow pink, the lighthouse sits alone at the end of a long narrow road, and the sea does everything you have ever dreamed it might.
Leave yourself enough time to catch the last comfortable ferry back. The night ride into Ibiza Town, with Dalt Vila lit up on the hill and the evening just getting started on the other island, is the kind of thing that reminds you why you came to the Balearics in the first place.
Formentera does not ask for much. A good pair of sandals, a loose plan, and the willingness to move slowly. Give it a day, and you might find yourself already scheming how to give it a week.
