Why should I go?
Slung between two rocky headlands, the slender waistline of Formentera wriggles with pleats of sandy coves and indigo inlets. Its interior is overrun with wild rosemary, fragrant pine trees and iridescent blue-green lizards. Sand-coloured buildings dot the arid landscape, infrequently clustering into sleepy fishing villages that strive to make at least some impact in the diminutive capital of Sant Francesc Xavier.
And it's that lack of impact that's really the point: Formentera is all about keeping things low-key, low-development and low-stress. It's a place to kick back and experience nature, to explore the network of hiking and cycling trails stretching across the island, to hide out on some of Spain's least crowded beaches, and to lose track of time over a long, lazy lunch.

Why is now a great time to visit?
Visit Formentera now and you'll experience the island at its best. Still relatively undiscovered, it has so far skirted the attentions of package tour operators, while the no-airport, boat-only access helps to keep things feeling that bit more remote. A ban on new beachfront properties has left the coastline wonderfully untamed, with a vast swathe of the island's northern stretches protected as a nature reserve.
In fact, Formentera has embarked on an eco-crusade, with new eco-ferries running to Ibiza, a crop of sustainable boutiques popping up and regulations set to kick off in 2019 that will limit the entry of vehicles to the island to help reduce CO2 emissions.

What are the beaches like?
Cancel your trip to the Caribbean - that limpid water and pale sand abandon is much closer at hand. Formentera is home to some of the best and most deserted beaches in Spain, with water clear enough to make even the Maldives a little nervous.
The sweeping bay of Platja de Migjorn is a perennial favourite - a 5km swathe of sands lined with tumbling vegetation and a few low-key beach bars. Yet to experience the wildest coastline you need to head to the Parque Natural de Ses Salines. A protected wetland nature reserve that has absorbed the island's north. Here, a pristine sandy peninsular unfurls itself, scattered with rocky outcrops and shallow lapping lagoons. And just off the tip of the peninsular is the dot of Espalmador, a private island that can be reached by boat from La Savina.
Guarded by a lone house, the island is entirely made up of billowing golden sand dunes topped with swaying grasses. Any description of Espalmador falls right into tropical castaway territory: softly sifted pale sands surrounded by turquoise waters riddled with deep pools of indigo.

What can I do in Formentera?
Formentera isn't just about flopping on beaches. Rent a kayak and you can explore the island's hidden caves, or try diving and snorkelling - thanks to the vast UNESCO-protected underwater posidonia seagrass fields, which filter the water, you'll find the visibility here second-to-none.
Meanwhile on land, the relatively flat terrain is ideal for hiking and cycling, with 32 marked Green Routes making up a network of more than 100km of paths. Even more adventurous, Walking Formentera organise various trips from cave explorations to trail runs.
For a small dose of civilization head into the tiny capital of Sant Francesc Xavier. The village consists of a charming cluster of low-level white buildings finished with blue shutters, iron balconies and draped with fuschia-hued Bougainvillea. At its heart is the sunbaked central square, where a heavily fortified eighteenth-century church glares across at the town's oldest bar. This is a place to potter around little boutiques, enjoy lunch and browse your way through the Saturday farmers' market.
