On the eve of Sant Joan, the whole island seems to stay up past midnight. It's Mallorca's midsummer night — the shortest of the year — and it's marked the way it has been for centuries: with bonfires on the sand, fireworks over the water, music in the plaça, and a dip in the sea for luck. There's no single place to be, because everywhere is doing its own version at once. This is a route through four of them. It starts in **Palma**, where the Nit de Sant Joan turns the seafront into the island's biggest celebration — crowds, fire and the cathedral lit up behind it all. Up in the Tramuntana, **Deià** keeps things more intimate, its festes winding through steep stone streets above the coast. Over on the east, **Son Servera** throws one of the liveliest village fiestas of the season. And along the shoreline, the **revetla on Mallorca's beaches** is the people's version — families claiming a patch of sand, lighting small fires and seeing in the 24th together. Pick one and commit, or hop between a couple if you're near the right towns. Either way, the trick is the same everywhere: stay out late, follow the smoke and the music, and don't be surprised if the night ends with your feet in the water.
