Sa Talaia is 475 metres, which does not sound like much until you are standing on it and can see the whole island at once — Formentera to the south, the salt flats, es Vedrà off the west coast and, on a clear morning, the mountains of the mainland.
The walk up takes a bit over an hour through pine forest on an old shepherds' path. It is a steady climb rather than a hard one; if you can walk for an hour without stopping, you can do this. We go slowly, and I stop often — partly for you and partly because there is a lot to point out: the wild rosemary, the fire watchtower, the terraces that were farmed here for centuries.
At the top we sit down and eat. I bring a proper tortilla de patatas, made that morning, with bread, tomatoes and olives, and something cold to drink. Eating a tortilla on the highest point of the island, looking at the whole of it, is a better lunch than most restaurants will give you.
