Nobody at a beach club in Ibiza will tell you the rules. That’s the point. If you don’t already know how things work, you’re not supposed to be sitting in the good chairs.

The basic structure: there are sunbeds, there are day beds, there are tables, and there are cabanas. Each tier costs more, expects more, and looks down on everything below it with the serene confidence of someone who hasn’t checked the bill. A standard sunbed at somewhere like Nikki Beach costs £30 to £60 with a minimum spend attached. A day bed is £80 to £150. A table with bottle service starts at £300 and climbs to whatever number stops feeling real around midnight. The cabanas and VIP terraces are not listed publicly, because if you need to ask, the answer is no.

Bottle service is where the theatre gets its budget. A bottle of Grey Goose that retails for £45 arrives in a procession: sparklers, a pair of women in bikinis carrying it overhead, possibly a small drum. The performance is for the people around the table, not the people at it. You are not buying vodka. You are buying a two-minute advertisement for what a massive fuckwit you are.

The dress code exists to screen people without saying anything a lawyer would flag. “Smart casual” at the door means whatever the guy on the rope decides it means that afternoon. Flip-flops get you turned away at Destino. The same flip-flops at a beach bar in Es Cavallet are fine, because Es Cavallet runs on a different social contract entirely. The rule is not about clothes. It is about whether you look like you belong to the spending bracket the venue is protecting.

Reservations are the other mechanism. You can walk up to most beach clubs, but you will be told they are fully booked and then watched as the next table fills with someone who called a concierge. Booking direct rarely works as well as booking through a hotel, which is itself a class signal.  If you want to do this without spending £400 on vodka you’ll half-drink in 35-degree heat, the honest move is to book a sunbed early, order modestly, and accept that you are in the cheap seats at the opera. The music is the same. The sea is the same. The show is happening about twenty metres to your left, and the man in the pink polo shirt is already pointing at the sparkler menu again.

Or if you have any self-respect, skip the rope entirely. The island still has places that trade the velvet rope for an actual atmosphere. No minimum spend, no sparkler tax, no doorman deciding whether your sandals pass.

Here are five that get it right –

Sa Trinxa, Salinas beach. The oldest and still the best of the unpretentious lot. You walk to the far end of Salinas towards the rocks, past the hippies selling bracelets, and find a palm-roofed bar where the owner often plays the records himself. The crowd is the most mixed on the island, the cava sangria comes by the pitcher, and the party sometimes spills onto the sand. Beds exist and don’t cost the earth. This is what beach-club Ibiza felt like before the concierges arrived.

El Chiringuito, Es Cavallet. The upmarket end of unpretentious. It has proper white sunbeds, a lunch menu that takes itself seriously, and a genuinely warm crowd on Ibiza’s most relaxed beach. It isn’t cheap, but it charges for the food and the setting rather than for the privilege of being seen spending. Open for breakfast too, which tells you the priorities are right.

Experimental Beach, Cap des Falcó. Three French guys started it in 2012 on a rugged stretch of the salt flats, and it remains the sunset move. The cocktails are the draw and the steaks are better than they need to be. Getting to the water over the rocks is a faff, so spend the day at Salinas and roll in here for an early-evening drink as the light goes. Worth the bumpy track through the salt flats.

Jockey Club, Salinas beach. Family-run and still holding the line as a proper chiringuito while the rest of the island reinvented itself. Crisp calamari, Ibérico ham, good cocktails, laid-back tunes. No theatre, no rope, no performance. Just lunch by the sea done properly.

Cala Gracioneta, northwest coast. A tiny family-run spot in a small cove, the kind of place you don’t find on your first visit. The garlic prawns are among the best on the island and the whole operation runs on honest cooking rather than status. Turn up, eat, swim, stay four hours longer than you planned. Nobody is watching you do it.
