Hiring a bicycle on Porquerolles is a must. It allows you to cover so much more ground than if you walk everywhere, and adds to the sense of childhood adventure that includes rocky coves, forts on tiny bay islands and shaded paths that always lead to another vista of the sea. You could take a boat, of course, but then you'd miss out on one of the most sensuous aspects of this lovely place: the fragrance.
There are few reference works in English that offer information beyond superficial facts about the island, and those I did manage to find were old. The best was published in 1880, by a journalist called Adolphe Smith. Here is his ‘description of the most Southern Point of the French Riviera’:
No one was there, and we decided against a swim because when we looked carefully, the shallows were full of small mauve jellyfish - meduses, as the French call them: Medusas, after the Greek Gorgon monster with the face of a woman and hideous hair of snakes.
We hopped back on our bikes and pushed on, until we found a lovely beach for swimming and snorkelling within sight of the Fort du Petit Langoustier.
