Formentera is the smallest of Spain's Balearic Islands, and it's often called the "Caribbean of the Mediterranean" for good reason. Just a short boat ride south of Ibiza, it offers some of the most stunning beaches in Europe — white sand, shallow turquoise water, and a laid-back atmosphere that feels a world away from Ibiza's party scene.
Visiting Formentera by boat is the best way to experience the island. You can explore at your own pace, anchor at hidden beaches, and avoid the crowded ferries. This guide covers everything you need for the perfect 2026 day trip.
How to Get There: Departure Points
The crossing from Ibiza to Formentera takes between 25 minutes and 1.5 hours depending on your departure point, boat speed, and sea conditions. Here are the main options:
| Departure Point | Distance to Formentera | Approx. Time (motorboat) | Best For |
|---|---|---|---|
| Marina Botafoch (Ibiza Town) | 11 nautical miles | 35–45 min | Most popular, most boat options |
| Playa d'en Bossa | 9 nautical miles | 25–35 min | Shortest crossing, calmer waters |
| Es Cavallet / Ses Salines | 7 nautical miles | 20–30 min | Closest point to Formentera |
| San Antonio | 18 nautical miles | 60–90 min | West coast starting point, scenic route |
| Santa Eulalia | 15 nautical miles | 50–70 min | East coast starting point |
What Boat Do You Need?
Unlike license-free boats (limited to 2 nautical miles from shore), crossing to Formentera requires a licensed vessel. Your options are:
- Rent a boat with skipper: The easiest option. A local captain takes you across, knows the best spots, and handles navigation. You just relax. Prices start around €400–€600 for a half day.
- Rent a boat with your own license: If you hold a valid boating license (Spanish PER/PNB or international equivalent), you can charter a boat and captain it yourself. More freedom, more responsibility.
- Join a group excursion: Several companies offer shared catamaran or sailboat trips to Formentera with lunch, drinks, and snorkelling included. Great value at €70–€120 per person.
5 Best Beaches to Visit in Formentera
1. S'Espalmador (Illa de S'Espalmador)
Technically a separate tiny island between Ibiza and Formentera, S'Espalmador is your first stop on the crossing. The beach faces west with calm, shallow water that glows turquoise. There's a famous natural mud bath on the island's interior. Anchor in the bay (sand bottom, good holding) and wade ashore.
Anchoring: Drop anchor 30–50m from shore in 2–3m of water. Sand bottom with excellent holding. Avoid the rocky sections on the north side.
Best time: Arrive before 11 AM to claim a good spot. The anchorage fills up quickly in summer.
2. Ses Illetes
Consistently ranked among the top 10 beaches in the world. A narrow strip of white sand with turquoise water on both sides — it looks like a postcard. The water is incredibly shallow for 50+ metres from shore, making it perfect for wading and swimming. Beach restaurants serve fresh seafood and paella.
Anchoring: The designated anchorage zone is marked with buoys. Use the buoys (€15–€25/day fee) rather than dropping your own anchor to protect the Posidonia meadows. Dinghy to shore from the anchorage.
Best time: Mid-morning to early afternoon. It faces west, so afternoon sun is glorious.
3. Cala Saona
A picture-perfect crescent beach on Formentera's west coast. The sand is fine and golden, and the water transitions from crystal clear at the shore to deep blue further out. Red-rock cliffs frame the beach on both sides. There's a chiringuito (beach bar) right on the sand.
Anchoring: Anchor outside the swimming buoys in 4–6m of water. Sand bottom. The bay is partially sheltered from north winds but exposed to south and west. Check conditions before choosing this stop.
Best time: Sunset here is extraordinary. If your schedule allows, make Cala Saona your last stop of the day.
4. Es Caló de Sant Agustí
A charming former fishing village on the northeast coast. Small traditional boathouses line the rocky shore, and the water is remarkably clear. The atmosphere is authentic and unhurried. Several excellent restaurants serve fresh fish and local wines.
Anchoring: Limited anchoring space — this is a small harbour. Anchor further out and dinghy in, or use the small pier if space allows. Better visited by dinghy from a nearby anchorage.
Best time: Lunch time. The restaurants here are worth the visit.
5. Platja de Migjorn
Formentera's longest beach, stretching over 5 kilometres along the southern coast. It's divided into sections, each with its own character — some busy with beach clubs, others deserted. The water is slightly deeper than at Ses Illetes, making it better for swimming. Rocky sections create natural snorkelling spots.
Anchoring: Plenty of space to anchor along this long stretch. Look for sandy patches between the Posidonia beds. The eastern sections (toward Es Copinyar) are quieter.
Best time: All day — the beach faces south so it gets sun from morning to evening.

Practical Tips for the Crossing
Weather and Sea Conditions
The Ibiza–Formentera channel is generally calm in summer, but wind can pick up in the afternoon. Check the forecast on Windguru or Windy.com before departing. Ideal conditions: winds under 12 knots, wave height under 0.5m. If the forecast shows winds above 20 knots, postpone your trip.
Navigation
The crossing is straightforward. Head south from Ibiza and you'll see Formentera clearly on the horizon. Watch for the shipping channel markers and other boats. If you have a skipper, they'll handle everything. If you're self-captaining, use a GPS app like Navionics for real-time chart data.
Posidonia Protection Zones
Formentera is surrounded by UNESCO-protected Posidonia seagrass meadows. Anchoring on Posidonia is strictly prohibited and carries fines up to €100,000. Use designated mooring buoys where available, and only anchor on visible sand patches. When in doubt, ask your skipper or check with the local port authority.
