The Serra de Tramuntana is Mallorca as most visitors never see it — terraced olive groves and dry-stone walls dropping straight to the sea, honey-stone villages where Chopin and Robert Graves once settled in for the winter, and mountain warmth long after the coastal resorts have gone quiet.
The GR221 Experience covers the finest four days of the Ruta de Pedra en Sec — Estellencs to Sóller, through the heart of the Tramuntana. It's the GR221 at its most concentrated, with 2,100 m of climbing packed into 53 km — firm but achievable for anyone with reasonable hill fitness, and an obvious pick for walkers who want the highlights without the remote refuge night beyond Sóller.
