Nestled between limestone cliffs and a turquoise sea, Cassis is one of the most beautiful towns on the Mediterranean coast. This small Provençal fishing port, set against the Calanques massif, attracts lovers of nature, beautiful scenery and swimming every year.
The Calanques of Cassis, limestone cliffs shaped by time and the sea, offer a spectacular setting where secret coves, sea pines and crystal-clear waters create an idyllic setting for a refreshing break away from crowded beaches.
But to make the most of your visit, it is best to be well prepared: access to the calanques can be tricky, with strict regulations given the fragile environment. On foot or by boat is the best way to get to Cassis’ most beautiful creeks and beaches, with our personal tips for a successful and responsible dive.
Discovering the calanques of Cassis
Between land and sea, the calanques between Cassis and Marseille form an exceptional natural area. Declared a national park in 2012, this protected area is known for its breathtaking cliffs, wild coves and deep blue waters. There are three main calanques accessible from Cassis, some of the most emblematic in the Mediterranean.
The first, the Calanque de Port-Miou, is actually an ancient natural harbour sandwiched between two limestone cliffs. Long and narrow, it is now home to a marina, but remains an essential starting point for exploring the paths that lead to the other creeks.
A little further afield, the Calanque de Port-Pin has a peaceful charm all its own. Surrounded by maritime pines and with a small pebble beach, it is an ideal spot for swimming in an intimate, unspoilt setting.
Finally, the Calanque En-Vau, undoubtedly the most spectacular, is well worth a visit. Tucked between tall white cliffs, it is a picture on a postcard. Getting there, on foot or by sea, requires some effort, but the reward is worth it: a deep bay, with turquoise waters, where nature seems untouched.
Swimming in the calanques: what you need to know
The reputation of the calanques of Cassis is well established. With their steep cliffs, secluded coves and crystal-clear waters, they are one of the most beautiful swimming spots in Provence. But swimming in the calanques requires some organisation and a few precautions are needed to fully enjoy this unique experience.
Access is sometimes demanding, but always worthwhile
Access to the calanques of Cassis is mainly on foot, via footpaths of varying difficulty. The start is often from the calanque of Port-Miou, accessible from the calanques car park on the outskirts of Cassis. The walk takes between 30 minutes and 1 hour, depending on the cove you choose and the pace you set. In summer, the paths may be closed on certain days due to fire hazards: it is therefore essential to check the Bouches-du-Rhône prefecture’s website before making an excursion to the Calanques.
The summer heat can make hiking difficult, especially on rocky terrain without shade. We recommend leaving early in the morning, wearing suitable footwear and carrying plenty of water. The effort is worth it: on arrival, you will find a wild bay where you can swim perfectly, far from the crowds of traditional beaches.
Enjoy swimming in the lovely turquoise water but stay careful
The calanques of Cassis are known for their clear waters that are an irresistible invitation to swim. However, these are not guarded beaches. There are no lifeguard posts or special facilities. So you have to be vigilant, especially with children or people who are uncomfortable in the water. The depth can vary quickly and some creeks do not have gradually sloping beaches.
The pebbles and rocks can be slippery and the seabed can be steep. It is recommended to bring swimming slippers or water shoes. Experienced swimmers will appreciate the clarity of the water to explore the seabed close to the cliffs, but be mindful of possible currents and do not swim too far.
A fragile nature to be protected
The calanques are a protected area and every visitor has a role to play in its preservation. Swimming in the calanques should not be at the expense of the environment. It is strictly forbidden to smoke, light fires or camp in the National Park. All rubbish must be disposed of, including food leftovers. You should also avoid straying from the marked paths so as not to damage the sometimes very fragile Mediterranean vegetation.
Some of the most popular bays can give the impression of being just another tourist spot, but once you move away, you will find a wild bay ideal for swimming, far from all infrastructure. It is this immersion in unspoilt nature that gives the area its charm and its fragility.
When and how to optimally enjoy the calanques
The ideal time to swim in the calanques is from May to September. Outside the high season, the water remains pleasant (around 20-23°C in early autumn) and is less crowded. In summer, it is best to avoid the middle of the day, both because of the heat and the crowds. Calanques like Port-Pin and En-Vau can be very crowded in high season, which reduces their charm.
Avoid weekends, prefer to go during the week, early in the morning or at the end of the day, when the wild coves are less crowded for swimming and you are more likely to enjoy this beautiful setting and the turquoise waters of Provence.
Accessing the calanques by boat: possibilities and precautions
While hiking trails offer the most obvious access to the calanques, access by sea is an attractive alternative for those who want to discover the wild coves without having to go on a long hike… From the port of Cassis, you can hire a boat, with or without a boat licence, to discover the calanques in a different way. It is a special way to approach these spectacular bays, away from the crowds on the hiking trails. But you do have responsibility for your own safety and for respecting the environment with a boat.
Boat hire in Cassis: different options depending on your level
Several service providers offer boat rentals from the port of Cassis. For those with a boating licence, renting small motorboats is quick and easy. For others, boats without a licence are also available. These generally have limited power and range, but you can easily reach the first calanques, such as Port-Miou and Port-Pin.
Boat trips with skipper are also available. These packages offer maximum comfort: you don’t have to worry about navigation, the crew knows perfectly the permitted areas, the seabeds to avoid and the weather conditions of the day. It is the most relaxing way to discover the calanques via the sea.
Know the rules
Since the creation of the Parc National des Calanques, boating and anchoring have been strictly regulated. Anchoring is prohibited in certain areas to protect Posidonia meadows, underwater plants essential to the marine ecosystem. Ecological mooring buoys are sometimes available, but in limited numbers.
Before heading out to sea, it is strongly recommended to consult local sea charts or inquire at the boat rental company. It is also essential to respect speed limits when approaching the calanques and be careful in areas frequented by swimmers, kayakers or paddlers.
Even if the sea seems calm in summer, this can change quickly. It is essential to check the weather forecast before heading out. Winds can suddenly pick up, especially the mistral, making sailing difficult or even dangerous.
Safety first
We recommend taking the following items on board:
- Plenty of drinking water for everyone
- sunscreen
- a hat or cap,
- a communication device (charged phone or VHF radio),
- life jackets, including for children.
Once you arrive in the bay, anchor carefully, take care not to damage the seabed and always keep an eye on your surroundings.
A privilege to enjoy respectfully
Discovering the calanques from the sea is a fantastic experience. Swimming in a secluded bay, far from all the crowds, is a privilege. But this privilege comes with a duty of respect for the environment: no loud music, no leaving litter on the premises and discretion not to disturb the peace of the place.
Private tips
If there is one place in Provence where swimming takes on a whole new dimension, it is here, in the calanques of Cassis. Here are some tips for a great day out and an unforgettable experience.
Our favourite coves for swimming
- Port-Pin, on weekdays and early in the morning, remains our favourite for an accessible swim, in a sheltered bay fringed by pine trees and with no noticeable current.
- For a more adventurous experience, En-Vau is worthwhile, provided you are well shod and leave early. The water is cool and the cliffs create a unique atmosphere.
- By boat, you can reach some small, unnamed bays between En-Vau and Devenson only by sea. They are much less frequented, but require caution and good navigation (and perfect weather).
Access conditions
Due to weather conditions, fire danger or other reasons, access to the forest paths leading to the calanques may be closed. Before leaving, consult https://www.myprovence.fr/ : ca-s-agite-dans-le-local/envie-de-balade or the website of the Cassis Tourist Office : Office du Tourisme de Cassis
The best times to avoid the crowds (and sunburns)
Between 8 and 11 a.m. the calanques are still quiet, the light is soft and the temperature pleasant, even in the middle of summer. After 3pm, hikers start to leave again and the light turns golden: ideal for a last dip in peace.
A good compromise: hike + boat
For a combination, shuttle bus or boat. For example: hike to En-Vau and then organise a return trip by boat from Port-Miou. This way you can explore the calanques from both directions, without extra physical effort.
Information Cassis and the Calanques
Boat hire
We recommend using the hire companies located directly in the port of Cassis. They are well informed about the rules of the National Park and always give good advice. Some even offer “responsible” routes that avoid sensitive areas.
Hassle-free parking
The Gorguettes car park, at the entrance to Cassis, offers a free shuttle bus to the city centre in high season. This means you won’t have to wander the port’s narrow streets for long. For early birds, the Presqu’île car park (near Port-Miou) is a good option, but it fills up quickly.
After swimming: enjoy the end of the day in Cassis
After a day between the sea and the cliffs, there is nothing better than relaxing in the centre of Cassis. A stroll along the port is a nice end to your day trip, with its colourful facades, fishing boats and lively promenade.
It is the perfect opportunity to enjoy a homemade ice cream or a drink on the terrace, overlooking the last golden reflections on the water. In the late afternoon, the atmosphere becomes quieter, the narrow streets flooded with strollers and the atmosphere is special.
For dinner, you only need to stray a little from the quayside to discover the small restaurants hidden in the narrow streets of old Cassis. You’ll find local dishes, often Mediterranean, served in a quieter, more characteristic setting. A great way to round off your day out.
