The walls of Dalt Vila turn copper behind the stern about ten minutes after you leave the pontoon, and then Ibiza flattens into a low grey line. October takes the heat out of the crossing and most of the traffic out of the anchorage, so what is left is a sandbar, a wind that changes its mind around lunchtime, and a skipper watching the depth sounder for sand rather than seagrass. This is the month the Formentera day stops feeling like a shuttle run and starts feeling like a sail.
What the day actually is
Strip away the brochure language and a private catamaran day is simple: you charter a whole boat with a skipper, cross ten to twelve nautical miles of open water, spend most of the day anchored off Formentera's north-west sandbar, go ashore if you want to, and come back with the sun behind you. Nobody sells you a seat next to a stranger. Balearic rules cap a private charter at twelve guests plus the skipper and crew, which is the single most useful fact about the format — it comfortably takes a family or a group of friends, and it will not take a coach party, so do not try to merge two groups into one boat.
The sailing itself is honest but undramatic. Under engine the crossing takes about an hour. With enough breeze to shut the engines down it can stretch to two, and in October you often get exactly that: a usable northerly in the morning that makes the outbound leg a real passage rather than a transfer. Cruising catamarans are stable and shallow-drafted, which matters because the good anchorages here are in two or three metres of water over bright sand.
Leaving from Marina Botafoch
Almost every private Formentera day starts at Marina Botafoch (Puerto de Ibiza, across the water from the old town), which is where the charter fleet keeps its pontoons. It is free to walk around and worth a look even if you are not sailing, but boarding happens only by arrangement — you are given a berth number and a time, and the crew meets you at the gate.
Whole-boat day charters out of here run from roughly €1,200 to €3,500 depending on the size and age of the catamaran, the crew and the date. The bookable option attached to this page is listed from 3,383 USD per person, so read carefully what any given price includes before comparing it with anything else: fuel, the skipper, food and drink, and mooring fees are all variables, and on a private boat the difference between a quoted per-person rate and a whole-boat rate is just arithmetic about how many of you turn up.
Ask for a morning slot. Leaving Botafoch between 09:30 and 10:30 gets you the Dalt Vila view on the way out — the first photograph of the day, and the only one most people keep — and puts you on the sandbar before the lunch tenders start moving. If you are building a longer stay around the trip, the harbourside hotels are the obvious base; our Ibiza hotel search covers that side of the water, and the wider Ibiza guide has the rest of the island.
The sandbar and the seagrass
Platja de ses Illetes (Ses Salines Natural Park, Formentera's northern tip) is the reason the trip exists. It is a public beach — no door policy, no entry gate from the water — and in high summer it carries an absurd number of boats. In October it thins out noticeably, and so does the service: the sunbed concessions wind down with the season, so bring your own shade and expect fewer staffed options than the photographs suggest. Access charges inside the natural park apply to vehicles during the restricted summer months only, which is irrelevant to you arriving by sea.
The catch is underfoot. The seabed here is protected posidonia meadow, anchoring on it is banned, and through 2026 monitoring vessels have been out enforcing it. A good skipper either drops on clearly marked sand or takes a reserved buoy, and will say no to the pretty-looking patch you are pointing at. If your skipper shrugs and anchors anywhere, that is a bad sign about everything else on the boat.
The second thing a skipper watches is the Tramuntana. When the north wind makes Illetes choppy and uncomfortable, the move is around to Platja de Llevant (east side of the same sandbar, Formentera), a wide open beach with almost no infrastructure — good for a group that wants space rather than service, poor if you were counting on a beach bar. In October the wind genuinely decides which side of the sandbar you spend your day on, so treat the itinerary as a plan and not a promise.
S'Espalmador and the end of the mud baths
North of Illetes sits S'Espalmador (uninhabited island, Ses Salines Natural Park), reachable only by private boat — there is no ferry — which is exactly why a chartered group gets it and the day-tripper crowd does not. The mooring field has fifty-one buoys colour-coded by boat length and they must be reserved in advance, so this stop is a decision your skipper makes the day before, not something you request mid-morning.
One myth needs killing in print. The mud baths are prohibited. The island lies inside the natural park, the pools are off limits for bathing, and the only correct way to see them now is from the boardwalk. Plenty of older guides and a great deal of social media still show people wallowing in them; those pictures are either old or illegal. Landing on the island itself is free, and the walk across to the lagoon and the beach on the far side is the quietest twenty minutes of the day.
Lunch within tender distance
The two serious tables sit on Illetes itself, both built around arrival by sea. Juan y Andrea (Platja de ses Illetes, Formentera) has been there since 1971 and is still the island's most recognised restaurant. It runs its own tender off VHF channel 74 and will collect you from your anchored catamaran, which is a genuine service and not a gimmick. It is also why the lunch slot is taken by other boats long before you think to ask: book ahead, because walk-ins are a gamble. Expect a serious bill — lobster and whole fish are priced by weight — and understand it is a lunch-and-afternoon place rather than a dinner one.
A few hundred metres away, Es Molí de Sal (Platja de ses Illetes, Formentera) is the more composed alternative: anchor in front, they come out and collect you, reservations are online. Same price bracket, rice dishes and whole fish at Formentera beachfront rates. The timing warning matters this month — it closes for the 2026 season on 16 October, so a late-October charter loses it entirely.
If you want something lighter and friendlier to a table of friends, Beso Beach Formentera (Cavall d'en Borràs, just short of Illetes) runs May to October with daily service from early afternoon, which makes it one of the few beach clubs still open in this window. The kitchen is paella-led, group bookings are normal, and a phone or web reservation is strongly advised. Sunbeds cost extra on top of the food.
Going ashore at La Savina
If the group wants wheels for the afternoon, the landing point is Port de la Savina (Marina de Formentera, north coast), where the scooter, bike and electric-car hire desks sit right on the quay. Landing by tender is free; berthing the catamaran here is premium in season; scooter hire runs roughly €30 to €50 a day. Be realistic about what you will see: the port is mid-upgrade through 2026, with ro-ro ramp modernisation and a new sixteen-year marina concession in progress, so you step ashore into construction hoarding rather than a postcard quayside.
Bikes are the better choice for a short afternoon. The land behind the port is flat, the lanes are quiet in October, and the ten-minute ride inland to the island's old quarter is one of the nicest stretches of road here. Scooters make sense only if you intend to reach the far end of the island and back before the boat has to leave.
Inland in an afternoon
Sant Francesc Xavier (Formentera's old quarter, ten minutes from La Savina) is the first stop and the reality check. The square's cafés absorb a group easily outside peak lunch, coffee and a bite runs €5 to €20, and the 1720s–30s church tells you what the island used to be: built fortified against raiders, with a spy hole in the door to shoot through.
Two doors down from that history is Museu d'Etnografia de Formentera (Sant Francesc Xavier), free and tiny — a handful of rooms on salt, fishing and subsistence farming, and the one indoor stop that explains what you have been looking at all day. More than about eight of you should go in shifts. It keeps short civil-servant hours, mornings and midweek with limited Friday evenings, so confirm before you build an afternoon around it.
At the far east end, Far de la Mola (La Mola plateau, Formentera) is the island's best cheap view and now a genuine attraction rather than a photo stop: the lighthouse has become a cultural space holding fifty-six donated works by artists tied to the island. Entry is €4.50 general, €2.50 for students and retirees, free for under-18s and residents. It is closed on Mondays, and the exhibition rooms are small enough that a large group should split and go in waves.
The other lighthouse, Far de Cap de Barbaria (southern cape, Formentera), is unstaffed and free, and it is the cinematic one — it carries the Sex and Lucía association. The approach is single-track with a small parking area, and the walk out across the cape is treeless and hot even now, so take it late in the afternoon rather than at midday.
For the honest counterweight to all of the above, Es Caló de Sant Agustí (north coast below La Mola) is a working fishing harbour where the escars — the stone dry docks — were declared a site of cultural interest in 2002 and are still in use. It is genuinely small: the harbourside restaurants will take a group with notice, and the cove itself is cramped for a large party.
Sunset on the way back
The standard homeward move is to swing down the west side and anchor off Cala Saona (west coast, Formentera), the only real sandy cove among the cliffs there and the obvious sunset-side stop. It is free, with room for a boat party, and the red rock against the water is the colour people actually remember from the day. Sunbed and restaurant service is seasonal, so a late-October group should expect fewer staffed options.
If you have hired wheels and are staying ashore until the last tender, two places on the Migjorn road hold up in October. Blue Bar Formentera (Migjorn, south coast) opens roughly March to November and is the long-running chill-out institution rather than a volume bar; its sunset service runs a defined early-evening slot and fills from around 19:00, and booking matters far less now than it does in midsummer. Up the La Mola road at kilometre 11, Chiringuito KM11 (Migjorn, south coast) is the correct current name for the kiosk that guidebooks still list as the Pirata Bus — same staff, same scruffy charm, under new signage since August 2024. It is walk-up only: draught beer around €3.50, a mojito €12, sandwiches €7.50 to €8.50, and it keeps going into winter on a Friday-to-Sunday schedule.
How long it takes and when to leave
Budget the whole day — around seven hours from boarding to stepping back onto the pontoon. A workable October shape: board at 09:30, cross under sail if the wind allows, anchor off Illetes by 11:00, swim before the tenders get busy, lunch at 13:30, ashore or across to S'Espalmador in the early afternoon, and start back from the west coast around 17:30 so you are not making the return leg in the dark. Sunset is early enough this month that an ambitious inland loop and a sunset anchorage do not both fit; pick one.
On booking: the attached bookable option runs seven days a week, Monday through Sunday, so the day of the week is not the constraint — the weather and the restaurant tables are. Reserve lunch and any mooring buoy before you sail, because those are the two things that cannot be fixed from the water.
Is it worth it in October
For the right group, yes, and more so now than in August. The case against is straightforward: this is a four-figure day whichever way you pay for it, there is no ticket-at-the-door version of a private boat, and if the Tramuntana gets up you will spend the day on the sheltered side of a sandbar rather than the one in the photographs. Weather risk in October is real and the honest operators will tell you so.
The case for is the thinning. Fewer boats on the sand, water still warm enough to swim without thinking about it, no scramble for a buoy, and a skipper with time to actually sail rather than queue. The format suits a family that wants a day with no logistics, or six to twelve friends who would rather split one boat than book twelve seats on something crowded. It suits couples less well in pure value terms — you are paying for a boat, not a seat. The bookable tours here carry 180 traveller reviews, with the top-rated one at 5.0 out of 5 from those 180 reviews, which tells you the format delivers when the day goes to plan.
Best time to go
Within October itself, the first half is the better half. Before 16 October you still have both headline restaurants open; after that date Es Molí de Sal is shut for the season and the Illetes lunch options narrow to one serious table plus the beach club. Water temperature holds up through the month and air temperature is pleasant for walking the capes rather than punishing.
Across the day, mornings are calmer and clearer; afternoons bring more breeze, which is good for sailing and worse for the swim platform. Across the week, nothing on the water changes, but Monday closes Far de la Mola and the museum's short midweek hours rule out a loose afternoon plan — so if the island's two indoor stops matter to you, sail midweek and go ashore early.
Practical notes
Getting to the boat. Marina Botafoch is a short taxi from Ibiza town or a walk around the harbour from the old town side. Arrive fifteen minutes early; a charter leaves on its slot.
Cash. Card works at the restaurants, the lighthouse exhibition and the hire desks. Carry €40 to €60 in small notes anyway — kiosk bars, tender tips and the odd quayside kiosk are easier with cash.
What to bring. Soft bag, not a hard case. Reef-safe sunscreen, a light windproof layer for the return leg, trainers or sandals you can walk the Barbaria track in, and a towel if the boat does not supply one — ask, because many do.
Budget. Whole-boat day charters from roughly €1,200 to €3,500; the bookable option attached here is listed from 3,383 USD per person. On top of that: lunch at €€€€ rates if you choose either Illetes restaurant, mooring buoy fees by boat size at S'Espalmador, €4.50 for the lighthouse exhibition, and €30 to €50 a day if you hire a scooter at La Savina.
Rules worth knowing before you board. No anchoring on posidonia, no bathing in the S'Espalmador pools, twelve guests maximum plus crew, and buoys at S'Espalmador by advance reservation only. All four are your skipper's responsibility and all four are worth checking they take seriously.
