Go sailing from any number of beaches, horse-riding up into the hills or along the coast, or mountain-biking. Corsica excels as an extreme sports destination but many activities can be easily modified for children. With older kids, there's white-water rafting, canyoning and excellent fishing and diving.
Head for the beaches around L'lle-Rousse and Calvi – not only some of the most beautiful on Corsica but also ones with the best family facilities. They do get packed in the height of summer – for alternatives, try Campomoro or La Liscia, where the watersports are superb and there are good cafés.
Don't miss Les Calanques de Piana, a spectacular landscape of red granite cliffs carved into bizarre shapes by nature, spiralling 300m over the sea.
Make time to explore some of the island's fascinating towns, including the capital Porto Vecchio and Bonifacio.
