Formentera

"Formentera makes you leave your car at the ferry and walk the last part slower than you planned to."

No airport, no big hotels, no hurry — Formentera is what the rest of the Balearics might have stayed if the ferry crossing were just a little less convenient.

There’s no airport on Formentera, and that single fact shapes almost everything else about the island. Every visitor arrives the same way — by boat from Ibiza, forty minutes across a strait so clear you can watch the seabed change color beneath the hull — which keeps the place smaller, quieter, and stubbornly resistant to the density that swallowed parts of its northern neighbor. I came for a day trip and stayed three, mostly because I kept underestimating how far a bicycle could take me and how little I wanted to leave.

Ses Illetes and the Water That Doesn’t Look Real

Ses Illetes, the sandbar beach on Formentera’s northern tip inside the Ses Salines Natural Park, is routinely ranked among the best beaches in Europe, and the first time I stood in it I understood why the comparisons to the Caribbean aren’t hyperbole — the water sits in bands of turquoise and pale jade over white sand so fine it squeaks underfoot, shallow enough to wade out fifty meters before it reaches your waist. The whole park straddles the strait between Ibiza and Formentera and protects one of the last intact Posidonia oceanica seagrass meadows in the Mediterranean, an ancient marine ecosystem — some individual meadows are estimated among the oldest living organisms on Earth — that keeps this water so exceptionally clear. UNESCO listed the Ibiza-Formentera Posidonia beds as a World Heritage site specifically for that reason, more for the seagrass than the sand.

A Roman Road, a Lighthouse, and Not Much Else

Formentera’s interior rewards slowness. I rented a bike in La Savina and rode the flat, dry roads past the ancient salt pans toward Cap de Barbaria, a windswept limestone plateau on the island’s southern tip, empty except for scrub, a small stone watchtower built against Barbary pirate raids, and a lighthouse where the land simply stops at a cliff with no railing and no warning. On the way I passed remnants of what’s believed to be a Roman-era road and the megalithic Ca na Costa burial monument, a sepulchre from around 2000 BC that predates the Romans, Phoenicians, and everyone else who later claimed this island, evidence that people were choosing to live here in the Bronze Age for the same reasons I couldn’t quite leave.

By evening most of the island seems to gather, unofficially, at whichever west-facing beach bar has the clearest view, and the sunset ritual here felt less performed than Ibiza’s — quieter, fewer phones raised, more people just sitting in the sand with a drink they’d bought from a cooler. I don’t think Formentera is trying to be humble. I think it just never had the infrastructure to be anything else, and has quietly decided that’s the better outcome anyway.

When to go: June and September deliver the clearest water and warm weather without July-August’s ferry queues and fully booked beach clubs.
