The standard Mallorca charter week starts in Palma, runs east along the south coast, hits Cala d'Or for dinner, then turns around. By Thursday everyone is in a fender-to-fender raft off Es Trenc with a 60-footer playing Spotify at 110 decibels. Brokers sell this route because it is short on transit time, easy on the crew, and forgiving of weather. It is also the dullest 110 nautical miles a charter client will ever pay €350,000 to cover.
The northwest coast is the alternative. From Cap de Formentor to Sant Elm, 75 nautical miles of Tramuntana cliff drop straight into 80m of water, with six anchorages that hold properly and one that does not. The water is colder by two degrees in July, the wind is unforgiving when it turns, and there is no marina between Sóller and Andratx. None of that is a bug. It is the reason the coast is empty on a Saturday in August while Cala d'Or is at 240% of capacity.
This is the list. Depths, holding, swell exposure, and the wind window each anchorage can take.
Why the south coast underdelivers
The south is shallow, sandy, and crowded. Cala d'Or, Cala Mondragó, and Portocolom share an anchorage culture that imported its worst habits from Ibiza around 2018. The sand bottoms hold well in 4m to 12m, the water is warm, and the cala mouths face away from the prevailing summer wind. None of that is unique. It describes Formentera, Menorca's south coast, half of Sardinia, and several anchorages in Sicily. The yachts that are 50m and over therefore stack in the same calas, the day-boat traffic crowds in behind, and the experience compresses.
The Tramuntana coast removes most of this by being physically hostile to mass tourism. There is no road access to Sa Foradada. There is no parking at Cala Tuent. The Sa Calobra access road is a 13-bend descent that day-trippers refuse to drive in peak heat. The result is that the calas hold yachts but not the volume of day boats, and the small boats that arrive tend to be from operators based in Sóller or Pollença, not from Palma.
The trade-off is real. Tramuntana wind from the NW can run at 35 knots from 11:00 onward if the gradient is wrong, and there is one anchorage on this coast where you do not stay overnight in any forecast that includes the letters N or W.
The six anchorages, north to south
1. Cala Formentor
Position 39° 56' N, 03° 08' E. Holding sand and weed in 8m to 14m at 200m off the beach. Charter clients who arrive expecting the postcard get an honest reminder that the Hotel Formentor closed for refit in 2021 and reopened under Four Seasons branding in 2024. The beach itself is now a Four Seasons beach club operation, which means a tender drop at the public end and a 300m walk if you are not staying at the hotel.
The anchorage is best in the morning. The bay opens north and catches any swell with a NW component, which builds through the day in July and August as the sea breeze fills. By 15:00 in a moderate Tramuntana day, the swell on the hook is uncomfortable on anything under 50m. The fallback is south of Cap Formentor into Pollença Bay, where the holding is excellent and the protection is total.
2. Cala Sant Vicenç
Position 39° 54' N, 03° 04' E. Holding sand in 6m to 9m, but the bay is small and crowded with day boats out of Port de Pollença from 11:00. We treat this as a one-hour lunch stop, not an anchorage. Yachts over 40m struggle to swing here without crowding the beach line. If the broker has sold you "lunch at Cala Sant Vicenç" as a headline anchorage, push back. It is not one.
3. Cala Tuent
Position 39° 51' N, 02° 47' E. Holding sand and pebble in 12m to 18m, 180m off the beach. The bay sits beneath the Puig Major massif at 1,445m, which gives it strong lee from any south or southeast wind. The hazard is the NW: with anything over 18 knots from 290° to 330°, this anchorage develops a reflective chop from the cliff that makes the boarding ladder dangerous.
Daytime use is excellent. The Es Vergeret restaurant above the cala takes tender drops at the small jetty and a captain who calls 24 hours ahead. Lunch reservations are not optional in July and August. Overnight in a settled forecast is fine and the bay is dark, which matters if you have guests who want a real star night. If the GFS run at 18:00 shows anything moving in from the Gulf of Lion within 36 hours, leave.
4. Sa Calobra
Position 39° 51' N, 02° 48' E. Holding poor sand and rock in 14m to 20m, often with patches that look like sand and are not. This is the cala the photographers want and the one most charter clients are sold without the qualification.
It is a daytime visit. Anchor 200m off the river mouth, take the tender to the small beach, walk through the 5m gorge tunnel to the Torrent de Pareis. Be back on the yacht by 14:00. Sa Calobra is the only anchorage on this coast where we tell brokers not to schedule an overnight regardless of forecast. The cliff geometry funnels and reflects swell, the holding does not match the depth, and the alternative is 15 minutes away at Cala Tuent.
There is a small tourist cafe on the beach. Do not eat there. Use Es Vergeret at Tuent instead.
5. Port de Sóller
Position 39° 48' N, 02° 41' E. The only enclosed harbor on the Tramuntana coast. Town moorings on the inner quay take yachts up to 35m, the outer Club Nautico moorings handle to 50m, and the deep bay outside takes anything to 80m on its own anchor in 14m to 20m sand. This is the overnight you build the week around.
Sóller earns its place not on the cala but on the town. The 1912 wooden tram still runs the 5km between Port de Sóller and the Sóller village, and the village itself has the only Michelin-recommended restaurant on this coast (Béns d'Avall in Deià is closer but is not in Sóller). The captain will hold the yacht offshore overnight in any settled forecast, and the harbor itself in anything unsettled. The fee is approximately €4 to €7 per meter LOA per night on the Club Nautico outer mooring in 2025-2026 season, fuel and water extra..
6. Sa Foradada
Position 39° 45' N, 02° 38' E. Holding sand in 10m to 15m, 250m off the peninsula. This is a lunch anchorage with one purpose: the Foradada restaurant, accessible only by boat or by a 2.5km walk down from the Son Marroig estate. Tender drop is at the small north-side jetty, reservation is mandatory, payment is cash, the menu is paella and grilled fish.
The peninsula gives lee from NE and N. With any S or SW, the anchorage is exposed and the tender ride to the jetty becomes wet. As an afternoon stop on a Tramuntana-day morning departure from Sóller, it is the right call. As an overnight, it is not protected enough to be safe on a deep-keel sailing yacht.
7. Cala Banyalbufar and Cala Estellencs
Position 39° 41' N to 39° 39' N, around 02° 31' E. Holding mixed sand and rock in 12m to 18m. These are paired afternoon anchorages on the southern Tramuntana, beneath the terraced vineyards that produce the malvasía wine the captain probably already has aboard. Neither cala has a jetty. Tender access is to a steep pebble beach, which means the chief stew has to call ahead and arrange the restaurant tender if guests want to eat ashore.
Both are exposed to anything from the south. In settled August weather they are excellent. From mid-September on, with autumn fronts rolling through, the wind clocks fast enough that we would not overnight here. The fallback is Port d'Andratx, 11 nautical miles southwest, which is the southernmost anchored harbor on the coast and which has hot showers, decent tender pick-ups, and three restaurants worth dinner.
Passed on
We pass on Cala Deià. It is too tight for any yacht over 30m, the holding is poor, and the swim shore is a 200m fetch onto rocks. The Béns d'Avall restaurant in the village above is worth the visit, but tender from Sóller (10 nautical miles) or anchor briefly off Sa Foradada and tender the 4km along the coast. Do not try to anchor at Deià.
We pass on Cala Pi del Vent and the unnamed coves between Estellencs and Andratx for charter yachts over 40m. They look good on a chart, they hold yachts to 30m fine, but the swing room for a 50m+ in a wind shift is not there.
We pass on the "anchor off Valldemossa" suggestion that some brokers float. There is no anchorage at Valldemossa. The town is 5km inland and 400m above sea level. What brokers mean is "anchor at Sa Foradada and tender for a transfer to a car to Valldemossa," which is fine, but call it that.
The Tramuntana risk window
The wind that defines this coast is the Tramuntana, blowing from 290° to 320° through the Gulf of Lion gap between the Pyrenees and the Massif Central. It is the same wind family as the mistral, just rotated 20 degrees east, and it arrives with the same warning signs. Falling barometric pressure over the Bay of Biscay, a clear line of cirrus running from northwest to southeast, and a sharp drop in humidity by mid-morning. Captains running this coast watch the 06:00 GFS run every day and the ECMWF 12:00 run as confirmation.
The risk window in a typical July and August is two to four days per month. In May and October, it is closer to six to ten days. Booking the northwest coast for a week in the second half of October means accepting that one or two of those days will be spent in Sóller or Pollença Bay, not on the cliff anchorages. That trade-off is the reason the route is empty and the south coast is not.
How to ask the broker about it
The question to put to your broker is not "can we do the northwest coast." Every broker will say yes. The question is "which two of the six anchorages can the yacht reach as an overnight, and where are the alternates if the Tramuntana fills." A broker who answers with specifics has run the route. A broker who answers with "the captain will decide on the day" has not, and the captain you get will default to the south coast on Tuesday morning.
If the broker offers Pollença as an embarkation port instead of Palma, take it. It saves 8 hours of transit on day one and puts you within reach of Cala Formentor by lunchtime. If the broker insists on Palma, the route still works, you just lose Cala Formentor as a meaningful daytime stop on day one.
FAQ
Can a 50m yacht use the Tramuntana coast in August? Yes, with a captain who monitors GFS at 06:00 and 18:00 and who has a fallback to Sóller or Pollença within 4 hours of any anchorage on the coast.
Is Sa Calobra safe to overnight? Only with no NW component in the forecast for the next 18 hours. The cove faces NW directly and reflects swell off the cliff walls. Most captains lunch and move to Cala Tuent or Sóller for the night.
What size of yacht works for the northwest coast? Anything from 24m to 70m. Above 70m, deep-water holding is fine but tender logistics for Deià, Banyalbufar, and Estellencs become awkward because there is no jetty to drop guests.
Are there day boats from Palma on this coast? Few. Most Palma day operators run east to Cabrera or south to Es Trenc. The day boats you see on the Tramuntana coast tend to be from Sóller or Pollença and they are smaller and quieter.
What is the right week-charter route from Pollença? Pollença to Cala Formentor (lunch), to Cala Tuent (overnight). Tuent to Sa Calobra (lunch only) to Sóller (overnight, two nights). Sóller to Sa Foradada (lunch) to Sóller. Sóller to Banyalbufar or Estellencs (afternoon) to Port d'Andratx (overnight). Andratx to Palma or back to Pollença for disembarkation. That is six nights on the cliff coast and one night in harbor.
