Formentera sits close enough to Ibiza's southern tip that you can pick out its low ridge from behind the salt pans, and it still takes a whole day to reach properly. The crossing is the quiet part: engine off past the islets, sails up, the water going from navy to a flat milky green as the sandbank rises under the keel. In October the anchorage off that sandbank is a different place from the one in August, with room to swing on the hook and a lunch table you can get without a negotiation.
What eight hours on the water involves
The shape of the day barely changes from one operator to the next. You meet the skipper on the quay around ten, motor out of the harbour, and turn south with the salt flats off the port side. Somewhere before the channel between the two islands the engine goes off and the sails go up, and for the next hour the only sounds are hull slap and the occasional winch.
Then it stops being a sail and becomes a swimming day. The boat anchors off the sandbar, the swim ladder goes down, the paddleboard comes off the bow, and the tender runs ashore for a lunch booking. The afternoon is either a second anchorage at the uninhabited island north of Formentera or a run round to the sheltered west coast, and you are back in Ibiza with the fenders out as the light goes.
You are not paying a skipper for sailing instruction. You are paying for anchoring judgement: reading where the sand stops and the seagrass starts, how much chain to lay, when a swell makes a lunch stop a bad idea. Most will hand you the wheel on the way home if you ask. Snorkel kit and a paddleboard are included on essentially every boat worth hiring; the item to confirm in writing is the tender, because without one you will spend the day looking at the beach restaurants instead of eating in one.
The marina you actually leave from
Almost every Formentera day charter starts at Marina Botafoch (across the harbour from Ibiza Town), not at the ferry terminal, and that single misunderstanding is the most common way people miss their boat. It has been working since 1987 and still behaves like a real port rather than a promenade: fuel station, boatyard, metered berths, taxis pulling straight onto the quay. There is no door policy and nothing to pay to walk in. From the old town it is a flat twenty-five-minute walk around the water, which is a good way to arrive with a dry bag over one shoulder; from anywhere else, taxi or park at the quay. Smart Charter Ibiza (Marina Botafoch) is explicit that its guests check in at the marina rather than the port, and the rest of the fleet here works the same way. Stay on the harbour side of town and you can walk to your boat; for everything inland and north, start with our Ibiza guide.
Not every boat leaves from Botafoch. White Island Charter (Marina Ibiza and Marina Santa Eulària) also departs from the east coast, which is a much shorter transfer if that is where you are staying, and GOA Catamaran Ibiza (Sant Antoni and the Ibiza town side) runs from both coasts. A west-coast departure saves road time and spends it again on the water, since Formentera is south-east of there, so ask the operator straight out how much of the eight hours goes on the delivery leg.
Choosing a boat for the size of your group
Charters Eleven (private day charters, Ibiza) takes up to eight guests on day charters and six on overnights, which makes it a small-group and family boat rather than a party one. Its listed eight-hour Ibiza-to-Formentera day is the closest like-for-like to the classic version of this trip; the price is quoted on request, and you should expect roughly €1,200 to €1,900 for the boat with skipper, fuel, taxes, cleaning, dinghy, paddleboard, snorkel gear and WiFi. The dinghy in that list matters a great deal more than the WiFi.
GOA Catamaran Ibiza does whole-boat private hire only, six to ten guests depending on the vessel, with eight catamarans including a 2025-build Lagoon 55 and the option of taking several boats for a larger party. A full day runs roughly €1,400 to €2,800 and up with skipper, fuel, paddleboard and snorkel gear built in; a four-hour half day is cheaper. It is verified operating in 2026 and states the standard southern run: the sandbar, the west-coast cove, the uninhabited island.
White Island Charter carries up to twelve plus skipper on a standard eight-hour charter with a wide 10:00 to 20:00 start window and extensions charged hourly; catamarans sit at roughly €1,100 to €2,500 per day and its RIBs considerably less. It has handled genuine group work, including a documented retreat using four catamarans for 44 guests. The RIB line is the honest option for anyone who wants the crossing over quickly: you trade the sail itself for speed, and some people will happily do that.
If the group is bigger than a catamaran's twelve seats, CharterAlia (group charters, Ibiza) is the operator that scales without you chartering a fleet. Standard catamarans take twelve plus captain, its MegaCata vessels are rated for 80 and 100 people, and it routinely builds 20 to 150-person events across several boats. All-inclusive day rates start around €900 for small catamarans and run past €3,000 for the large ones, with big-boat events quoted per head. All-inclusive here means fuel, taxes, captain, port fees, paddleboard, snorkel gear, speaker and cleaning, which is the only way to compare real costs between quotes.
Smart Charter's shared six-hour day trip is the benchmark that keeps all of this honest, from about €95 per person. Same destination, same anchorage, a deck you share. Its private hire runs from roughly €1,699 for a speedboat up to €12,999 for the biggest yachts, so the whole ladder is visible in one place.
The sandbar and the rules that come with it
Platja de ses Illetes (Ses Salines Natural Park, northern Formentera) is what the trip is for: a pale shelf of sand with water over it that barely looks like water. From a boat there is no gate and nothing to pay. Sunbeds and kiosk service work the sand, and groups land by dinghy.
The rule that matters is the seabed. Anchor only on the marked sand, never on the posidonia: fines start around €300, and a monitoring fleet patrolled all four islands this season. Your skipper knows exactly where the sand ends, which is a large part of what the charter buys you.
One October detail is worth knowing. Vehicle access by land is charged from 10 May to 15 October, €5 per car and €3 per motorbike in October 2026, with pedestrians, cyclists, electric vehicles and residents free. After 15 October the charge is gone. Boats are unaffected either way, so this only changes the arithmetic if you are weighing the ferry instead.
S'Espalmador and the rules worth reading first
S'Espalmador (Platja de s'Alga, the uninhabited island north of Formentera) is the second stop on almost every full day. It is privately owned, the beaches are public, construction is banned, and there are no facilities, no staff and nothing to land at, so everyone arrives by tender with their own water, food and shade. Moorings must be used rather than anchoring on the seagrass.
Two prohibitions to pass on before you get there. Walking or swimming the channel across from Formentera is banned and genuinely dangerous. The famous mud baths are now illegal under park rules, with fines reported around €1,000, so if someone aboard has an old photograph and a plan, that conversation is better had at the marina.
Lunch on the Levante sand
Juan y Andrea (Ses Illetes) has been run by the same family since 1971 and is the default lunch for every catamaran on the sandbar. It runs its own tender service (VHF channel 74 or +34 630 258 144) and serves lunch and the afternoon only, 13:00 to 19:30, with no dinner. The minimum spends are the thing to know: around €120 per diner on the sand, €150 for the seafront early slot, €250 for the open-ended afternoon slot, all before drinks. Big tables need booking weeks ahead in July and August; October is calmer, but a couple should do the sums before committing to the long afternoon slot.
Beso Beach Formentera (Ses Illetes, five minutes along the same sand) is the livelier, less formal counterpart, roughly €60 to €110 a head with wine, with no published minimum spend and groups welcome. Book ahead in peak weeks on +34 971 349 900. It opened on 30 April for the 2026 season and runs daily from 13:00 to 21:00 through October, which is the useful part: it is still serving when some of its neighbours have closed for the year.
Tanga (Levante side, Ses Illetes) has been open since 1978 and charges no minimum spend at all, unlike the places next door. Same sand, around €45 to €80 a head, and the most unaffected room on this stretch. It has its own dinghy service on 971 187 905 or VHF channel 06. If you are doing the day on a shared trip rather than a chartered boat, this is your lunch.
A salt mill and a west-coast afternoon
Es Molí de Sal (converted salt mill, near Ses Illetes) is the most photogenic lunch of the trip and an actual piece of the island's salt-trade past rather than a built beach club. Expect roughly €90 to €150 a head for serious rice dishes and whole fish; the terrace takes groups, you reserve on +34 602 409 690 or +34 620 170 040, and you arrive by tender. It opened on 30 April and works the May-to-October season, so an October booking sits near the end of its run. Book the later side of lunch and let it slide into the afternoon.
Cala Saona (west coast, Formentera) is where a good skipper takes you when the Levante side is blown out or too crowded to anchor cleanly. It is a public cove, free from the water, with cliffs that give it shelter and an anchorage that gets tight in season; you come ashore by tender. The best light of the whole day lands here in the hour before sunset, which is the argument for swinging west in the afternoon rather than sitting on the sandbar until the sails go up.
Cala Saona · Ramón Freixa (beachfront at the cove) is the reason to do it. The restaurant at the hotel changed hands this season and now runs as two concepts, Cala Saona Ramón Freixa by day and Sol Post Ramón Freixa in the evening, out of one venue and one kitchen. Daytime à la carte is roughly €70 to €120 a head and the evening tasting menu higher; it handles groups and private events. Reserve ahead and dinghy in from the anchorage.
The shorter day down the Es Vedrà channel
If eight hours and a channel crossing is more day than you want, point the boat west instead. Es Vedrà and Cala d'Hort (south-west Ibiza) make a four-hour half-day charter that costs a good deal less and never leaves Ibiza water. The rock has been a nature reserve since 2002: no landing at all, keep 50 metres off, and anchor only on the lighter sand patches south of Cala d'Hort. In high season you need to be in before 11:00 because the anchorage fills; October takes most of that pressure off, which is one of the quiet advantages of sailing here this month.
Booking ahead and what October changes
There is no queue to stand in. You are booking a boat rather than a seat, so the only scarcity is a specific vessel on a specific date. The private full-day sail operates seven days a week, and its season runs from 20 September 2026 through to 20 October 2027. October sits comfortably inside that, so nothing about the charter itself is at the edge of the calendar. Across the bookable options attached to this page there are 278 traveller reviews, with the top-rated one at 5.0 out of 5: a small and consistent sample rather than a mass-market one.
What October does change is the weather's veto. Get the reschedule and cancellation terms in writing before you pay a deposit, and ask what happens if the skipper calls it off on the morning. Lunch is the other thing to lock early, because boats are findable in October and the right table on the sand less so.
Best time to go
Early October is the best of it. The sea still carries the summer's heat, every restaurant on the sandbar is open, and the anchorage has thinned out. From 15 October the vehicle charge at the sandbar ends, which matters only if you are comparing with the ferry. Late in the month the clocks go back, pulling the last hour of light an hour earlier: a 10:00 start that finished in gold now finishes in dusk, so ask for an early start, put lunch at 13:00, and be on the west coast by five.
Weekdays beat weekends on the anchorage, and a 10:00 departure beats a lazy one by a wide margin: being anchored on the sand before noon is the difference between choosing your spot and taking what is left. If the forecast shows a strong easterly, say in advance that you are happy to reverse the route and do the sheltered west coast first.
What the same day costs without a boat
Port de la Savina (Formentera's port) is the honest comparison. Ferries from Ibiza Town run roughly €23 to €28 one way in October 2026 across several operators, the crossing takes 29 to 58 minutes depending on the boat, and departures run from early morning to around 01:00. Scooter, car and small-boat rental desks line the quay and take walk-ups in season.
The catch is geography and the timetable. Savina is about 4km from the sandbar, and you are tied to a return sailing. That 4km is flat and quiet, and on a rented bike it is a twenty-minute ride that is a pleasure in October air rather than a chore in August heat. For two people, a return ferry, two bikes and lunch at Tanga comes to a small fraction of a private charter and puts you on exactly the same sand.
Is it worth it
For six to twelve people splitting one boat, yes, clearly. Divide €1,400 by eight and the sail costs less per head than a mid-range dinner, and you get the one thing the port cannot sell you: your own anchorage, all day, with the ladder down and no ferry to catch. For a couple, the maths is harder to defend. A four-figure boat plus two €120 lunch minimums is a lot of money for a swim, and the shared six-hour trip at about €95 a head gets you to the same water. Families with small children should ask specifically about shade and the tender, because the day is long and entirely exposed. Anyone whose main aim is the sailing itself should book the full day rather than the half, and say so when booking. A skipper who knows you want sails up will give you an hour of it instead of twenty minutes.
Practical notes
Transport. Charters check in at the quay at Marina Botafoch, not the ferry terminal; taxis drop at the pontoon gates and there is parking on site. Allow fifteen minutes more than you think. East-coast stays should ask about a Santa Eulària departure instead. If you want to be able to walk to the boat, the harbour side of town is the place to sleep. Start with the Ibiza hotel search.
Cash. Charters take card and usually want a deposit on booking. Carry some cash anyway for tender crews, beach kiosks and the bike rental desks at the port.
Timing. Eight hours is the standard full day, four the half; start at 10:00, lunch at 13:00, west coast for the late light, and remember the clocks change at the end of October.
Budget. Full-day private catamarans run roughly €1,100 to €2,800 for the boat, all-in; a shared day trip is from about €95 per person; lunch is €45 to €80 at the informal end, €60 to €110 mid, and €90 to €150 or a €120 to €250 minimum spend at the top. A ferry return plus a bike is €50-odd and a different, slower, perfectly good version of the same day.
