Estany d’en Mas: Coastal Hike, Abseil & Sea Cave Exploration
The most unusual part of this Estany d’en Mas outing comes before you even enter the cave: you rappel 15 to 20 meters down a cliff to reach the sea-level entrance. From there, you swim through cold water into rooms decorated with stalactites, stalagmites, columns, and small lakes. It is part coastal walk, part climbing session, and part underground expedition.
I like the way the tour gives you two good choices at the key moment. You can use the rope, or swim to the cave entrance instead. I also like the small-group setup, with no more than 10 people, and the complete equipment package, including a wetsuit, helmet, harness, aquatic shoes, life jacket, backpack, and front light.
The main consideration is the water. You need to be a swimmer, and the return swim is about 120 meters. Rough sea conditions can make the route harder, and the cave water is cold even when the wetsuit helps. This is beginner-friendly for adventure activities, but it is not a gentle sightseeing tour.
The best parts of this coastal adventure

- A cliff entrance with a choice: Rappel into the cave from 15 to 20 meters up, or swim to the entrance if you prefer to skip the rope.
- A cave with real variety: Swim through two lakes and several rooms filled with stalactites, stalagmites, columns, and other old formations.
- A manageable four-hour plan: The outing combines a short coastal hike, technical activity, cave circuit, swim, and return walk without taking a full day.
- Strong guide support: Guides such as Paco, Matteo, Fillipe, Alfonso, and Dany have been praised for calm instruction, safety checks, explanations, and help in the water.
- Beginner access with limits: No previous abseiling experience is needed, but you must be able to swim and should be comfortable in open water.
- Good-value equipment package: The $88 price includes the guide, safety gear, insurance, cave explanations, and the abseil or swimming option.
Starting at Estany d’en Mas

You meet the guide in front of Petit Bar, where the guide will be beside the bar wearing a green shirt. This meeting point matters, since the experience starts from a specific parking area and not from the cave itself.
The first walk takes about 30 minutes according to the official plan, though some descriptions and past outings have made the approach feel closer to 45 minutes. Either way, this is a short coastal hike rather than a strenuous mountain trek. You walk beside the water toward Cala Falcó beach, with the coast providing a scenic warm-up before the more technical part begins.
I like this order. You do not arrive cold and immediately get clipped into a rope system. The walk gives you time to meet the guide, settle into the group, and see the coast before putting on the neoprene gear.
Bring sports shoes with a decent grip. After rain, the path can become slippery, so this is not the place for smooth-soled sandals. Sunscreen is also important. One practical point from the route: food and drinks are not included, and you should bring snacks and water for before or after the rappel and swim.

Rappelling 20 meters to the cave

At the coast, you put on your wetsuit and receive the safety equipment. The full kit includes a helmet, harness, neoprene suit, aquatic shoes, life jacket, backpack, and front light. The guide explains how the system works before you descend.
The 15 to 20-meter abseil is the tour’s biggest burst of adrenaline. If heights make you nervous, the guide can talk you through the descent. Dany, Paco, Matteo, Alfonso, and Fillipe are among the guides praised for clear communication and a reassuring manner, though the exact guide depends on the day.
The rope section is not presented as an advanced climbing challenge. You do not need previous experience, and the safety equipment is supplied. Still, you should expect a genuine vertical descent, not a symbolic photo stop. You will be suspended over the coast and lowered toward the cave entrance.
If you do not want to rappel, you can swim to the entrance. That option makes the activity more accessible, but it does not remove the need to swim in open water. A life jacket is available, and the guide can assist people who are less confident in the water, but non-swimmers should not book this tour.
The choice also lets you match the day to your mood. You might want the rope on a calm sea day, then choose the swim if you have a strong fear of heights. Or you might prefer to avoid the harness and make the water approach your main challenge.
Inside the sea cave

The cave is where the outing becomes more than a standard coastal activity. Once inside, you follow a circular route through several rooms. The guide uses the front lights to help you see the formations and explains the cave’s geology and history along the way.
The formations include stalactites, stalagmites, and columns formed over a very long period. The cave also has two lakes, so this is not simply a walk through a dry passage. You swim through sections, move between rooms, and watch your footing around wet rock.
The entrance may look small from outside, but the interior opens into a much larger world. That contrast is one of the strongest reasons to choose this tour. You get a sense of how much of the coast is concealed below the surface, without needing specialist caving experience.
The wetsuit is useful here, since the water can feel very cold. Several outings have taken place in cooler months, and the suits have helped keep people warm, but fit can vary. A poorly fitting rental wetsuit may let in more water and leave you chilled, so tell the guide if the suit feels loose or restrictive before you begin.
The cave floor can be uneven and slippery. Follow the guide’s instructions about where to step, especially when moving between the swimming sections and rock passages. A front light is included, so you are not relying on a phone flashlight in the dark.
This is also where the guide’s explanations add value. The outing is not only about posing at the cave entrance. You receive information about the formations, the cave, and its geological character while moving through the rooms.
The 120-meter swim back to shore

After the cave circuit, you return to the coast with a swim of about 120 meters. For many people, this is the part that requires the most steady effort. A wetsuit helps you stay on the surface, but it can make your swimming motion feel less natural, especially if you are not used to swimming in neoprene.
The sea can also change the feel of the route. In calm conditions, the swim may be straightforward. In rough conditions, you need stronger water confidence and must listen closely to the guide. One outing had rough seas, and the cave was still accessible, but the swim required a good swimmer.
The life jacket is optional, according to the activity details. If you are not a confident swimmer, use it. The guide may help participants in the water, but support does not turn this into a non-swimmer activity.
Once back on shore, you have time to rest and change into dry clothes before walking back to the meeting point. Bring a spare layer and a dry change of clothes. Your swimwear, wetsuit, and shoes will all be wet, and the coastal walk back will feel much better if you are not sitting in damp clothing.
The total time is listed as four hours. Allow some flexibility, since one outing took about five hours and 15 minutes. Group pace, sea conditions, time inside the cave, and changing can all affect the finish time.

How difficult is the experience?

The operator describes the tour as suitable for beginners, and no previous abseiling experience is needed. That is accurate as far as the rope work goes. The guide supplies the equipment and teaches you what to do.
The physical demands come from the combination of activities. You walk along the coast, climb or move around wet rock, rappel, swim in cold water, and walk back. None of these parts needs to be extreme on its own, but together they make this more active than a simple beach excursion.
You should be comfortable with:
- A 15 to 20-meter descent, unless you choose the swimming approach
- Swimming in open water
- A 120-meter return swim
- Cold water inside the cave
- Uneven and possibly slippery coastal ground
- Wearing a wetsuit and safety harness
The tour is not suitable for pregnant women or non-swimmers. If you have a strong fear of heights, the swimming option removes the rappel but not the sea crossing. If you get cold easily, consider the season and bring warm, dry clothing for the end.
Guide quality and group size

The small-group limit of 10 people is a real advantage here. The cave passages and water sections are easier to manage with a compact group, and the guide can keep an eye on each person during the technical parts.
The guides have different names depending on the departure. Paco has been appreciated for taking photos and keeping the group engaged. Matteo has been singled out for making people feel safe, while Fillipe has been praised for clear communication and a friendly manner. Alfonso and Paco have also been recognized for professional handling of the activity, and Dany helped a participant with a fear of heights feel comfortable on the descent.
You should still ask questions before starting. The guide is there to explain the route, safety gear, and cave sections, not to guess what makes you nervous. Speak up if your wetsuit does not fit, if you need the life jacket, or if the sea feels beyond your ability.
English and Spanish are offered. That makes the safety briefing and cave explanations easier to follow for many international visitors, though the exact guide and language mix can vary.
What the $88 price includes
At $88 per person, the cost is fair for a specialized half-day outing. You are paying for a guide, insurance, safety equipment, a coastal hike, the abseil, the cave circuit, and the route instruction. Buying or renting this full set of equipment separately would also add up quickly.
The value is strongest if you want several activities in one booking. A standard cave walk might cost less, but it would not include the cliff descent, water approach, wetsuit, helmet, harness, or life jacket. A basic climbing session would not give you the cave swim and geological explanations.
Food and drinks are not included. Bring water, sunscreen, and something to eat. You may not want a large meal immediately before the swim, but a snack for before or after the activity is sensible.
The experience also includes insurance, which is useful for an activity involving ropes and open water. It does not remove your responsibility to follow instructions or to judge your own swimming ability.
Weather, sea conditions, and route changes
This outing depends on the sea. Bad weather or unsafe water can lead to cancellation before the start, and the operator says you will be informed in advance when possible.
Conditions can also change the route. If the main cave cannot be reached safely, the guide may visit alternative caves that do not require entering the sea and may arrange another rappel. The route and schedule can therefore differ from the advertised plan, and the activity details state that no refund is issued for these changes.
That policy is worth understanding before booking. You are paying for a sea-based adventure, so nature has the final say. A modified outing may still include a cave and rappel, but it may not deliver the exact swim through the main cave that you expected.
Rain can affect the coastal walk as well. After wet weather, the path may be slippery. Good sports shoes, careful footing, and a willingness to accept a changed route are part of the deal.
What to bring and what to leave behind
Pack swimwear, water, food, sunscreen, and sports shoes. Add a dry change of clothes, even though only the first set is specifically required, because you will swim and wear a wetsuit.
Do not rely on your phone for photos. The activity includes a front light and backpack, but no underwater phone case or wet bag is listed. Some guides may take photos, as Paco has done, but that is not something to count on every time.
Alcohol and drugs are not allowed, and littering is prohibited. Keep your belongings secure, since the guide is not responsible for losses, damage, or extra costs caused by events beyond the guide’s control.
Should you book the Estany d’en Mas adventure?
Book it if you want a compact, active outing that combines a coastal walk, a rope descent, sea swimming, and cave exploration. It is especially suitable for people who like a little fear with their scenery and want a guide-led activity rather than an independent swim into unknown water.
Skip it if you cannot swim, dislike cold water, or want a relaxed beach day. The optional rappel makes the tour less intimidating, but the open-water sections remain central. You should also leave room in your schedule for the activity to run longer than four hours.
For most capable swimmers, the $88 price buys a memorable mix of experiences and a well-equipped introduction to coastal adventure. The best reason to book is not simply the descent. It is the surprise of reaching a small sea-level opening and finding a cave with lakes and ancient formations behind it.
