Cala Murtra: Immerse yourself in the beauty of an underwater world

Cala Murtra is a small, protected cove where the Cap de Creus coast meets clear Mediterranean water. The catamaran ride from Roses gives you cliff views, pine-covered slopes, and a short look below the surface through underwater windows.

I like two things here: the scenery feels genuinely wild, and the outing is short enough for families with young children. You can also swim, and the underwater viewing adds a little excitement without asking you to book a full-day boat trip. The catch is that the underwater stop may feel brief, crowded, and less impressive on a busy sailing.

I like the simple value of this trip. For about $24.08, you get roughly 90 minutes on the water, a look at the Cap de Creus shoreline, and time at one of the Costa Brava’s more remote coves. Just keep expectations sensible: this is a compact boat excursion, not a long snorkeling trip or a private cruise.

Key points to know before booking

• Cala Murtra is inside Cap de Creus Natural Park: The cove is surrounded by cliffs, pine trees, and clear water with little visible development.
• The underwater viewing happens at one stop: You may see fish through the catamaran windows, but the viewing period can be short because passengers are divided into groups.
• The outing suits families: Children especially seem to enjoy the underwater view, and most participants can take part.
• Swimming is possible: Bring what you need for a quick swim at the cove, though the supplied details do not promise a long beach stop.
• The beach is officially nudist: Cala Murtra is the only authorized nudist beach in the area, so you should be comfortable with that setting.
• Weather and minimum numbers matter: Poor weather or too few bookings can lead to a change of date or a full refund.

Sailing from Roses toward Cala Murtra

The trip begins in Roses, looking out across the broad bay before the boat follows the smaller coves of Cap de Creus Natural Park. That route is part of the pleasure. You are not simply being transported to a beach. You are watching the coast break into rocky points, narrow inlets, and pine-covered slopes.

The trip lasts about an hour and a half, so the schedule is easy to fit into a beach day. I would treat it as a scenic outing with one main attraction, not as an all-day coastal expedition. The short format works well if you have children, limited time, or want something gentler after a morning on land.

The catamaran gives you a broader view than you would get from the shore. You can look back toward Roses, then watch the coastline become more rugged as the boat reaches the protected area. The setting is especially appealing because the park has not been turned into a row of built-up waterfront resorts.

The boat may carry as many as 200 people. That maximum matters. On a quiet departure, the ride may feel relaxed and spacious. On a full sailing, the experience can feel much busier, especially around the underwater viewing area and the toilets. If you prefer quiet boat rides, ask about the expected passenger load before committing.

Why Cap de Creus Natural Park matters

Cap de Creus is one of the Costa Brava’s most dramatic coastal areas. Here, the natural setting is the main attraction. Cala Murtra sits among cliffs and thick pine growth, with bright blue-green water that can look especially clear in good weather.

The cove feels different from a standard resort beach. You are not going for a promenade, beach bars, or a long list of facilities. You are going for the contrast between stone, trees, sky, and sea. That simplicity is exactly why the stop works.

The cove is also officially a nudist beach. You do not have to assume that every person on the boat or at the beach will be nude, but you should know the designation before booking. Families may still enjoy the outing, yet parents should decide if this is the right beach setting for their group.

The protected location also explains why the boat does not offer a long series of stops. The point is to see a wild section of the coast without turning it into a heavily developed attraction. You get one main cove, a scenic approach, and a short chance to see the water below the boat.

The underwater viewing stop

The underwater windows are the unusual feature of this excursion. Instead of simply looking over the side, you enter a viewing area in the catamaran and watch for fish beneath the hull. This can be a nice introduction for children or for anyone who does not want to snorkel.

The view is not a private aquarium. The windows are described as fairly small, though another account found the viewing access spacious and comfortable. Both points can be true depending on where you stand, how busy the boat is, and how clear the water happens to be that day.

The main practical issue is time. Passengers may be divided into four groups, with each group receiving about 10 minutes of viewing while the others wait. That can mean roughly 30 minutes of waiting for some people. If you are expecting a long underwater presentation, you may come away disappointed.

The fish themselves are a pleasant bonus rather than a guarantee of a major marine spectacle. Good weather and clear water should help, but nature controls the show. I would tell children to expect a quick look at fish, not a guaranteed parade of sea life.

If your family is excited about the underwater windows, try to be ready when your group is called. The viewing period can pass quickly. Keep your attention on the water rather than expecting a narrated marine biology lesson. The available information does not identify a guide or promise a formal educational talk.

What happens at Cala Murtra

Cala Murtra is the central stop. The boat reaches the cove after following the coast, and you get time to take in the setting, look through the underwater windows, and possibly swim.

Several accounts describe the cove trip as especially good for families. Children can enjoy the novelty of the catamaran, the underwater windows, and the chance to spot fish without needing advanced swimming skills. The ride is also short enough that younger children are less likely to become restless than they might on a half-day cruise.

Swimming is possible, but the supplied details do not give a fixed swimming duration or promise that everyone will get a long swim. Bring a swimsuit and towel if you want to use the opportunity, but think of swimming as part of the stop rather than the whole purpose of the trip.

The cliffs and pine trees make the cove photogenic from the water. You can see why this stretch is protected. The appeal is quiet natural scenery, not a packed program of activities.

One point needs careful attention: Cala Murtra is the only authorized nudist beach in the area. That is not a minor detail for some families or couples. If you are uncomfortable with a nudist beach, the beautiful setting may not outweigh that concern.

A boat ride with mixed comfort levels

The catamaran itself receives both warm and critical reactions. Positive impressions focus on a comfortable boat, friendly staff, and a pleasant setting. The crew has been described as helpful and attentive, which matters when people are moving between the deck and the underwater viewing area.

The negative experience reported was tied to a very crowded departure, with about 175 students aboard. In that situation, passengers found it hard to hear announcements or speak comfortably, and the toilets were described as dirty. That is a sharp reminder that the passenger count can change the character of the trip.

With a maximum capacity of 200, this is not a small-group sailing. You should not book it expecting a private, quiet cruise. If you happen to travel during a busy school outing or peak summer period, the boat may feel more like public transport on water than a peaceful escape.

I would ask the operator about the expected group size if atmosphere is important to you. The experience provider is Els Blaus de Roses, and the trip is sold with a mobile ticket. Confirmation is provided at booking, so keep that ticket accessible on your phone.

Service animals are allowed, and the departure area is near public transportation. Most people can participate, though the supplied information does not give detailed mobility guidance for the catamaran or underwater viewing area. If you have specific access needs, confirm them before paying.

Is $24.08 a fair price?

At about $24.08 per person, the trip offers reasonable value if you want several small experiences in one outing: a coastal cruise, views of Cap de Creus, time at Cala Murtra, possible swimming, and underwater fish viewing.

The value is strongest for families. A child may see the catamaran itself as an adventure, then enjoy the underwater windows and the clear water at the cove. You also avoid paying for a much longer excursion if your group only wants a short taste of the coast.

The value is weaker if your main goal is snorkeling or marine life. The underwater viewing is brief for some passengers, and the windows may not give everyone a wide view. You might prefer an activity built around time in the water if that is your priority.

The same applies if you want solitude. The protected cove feels wild, but the boat may be busy. You are paying for access and scenery, not exclusivity.

The trip has earned an overall rating of 4.3 from 14 ratings, which suggests a generally positive experience with a few meaningful reservations. The strongest praise centers on family enjoyment, beautiful scenery, friendly staff, swimming, and the surprise of seeing fish or even dolphins during one outing. The sharpest criticism centers on crowding, poor conditions on a packed departure, and too little time at the underwater windows.

Choosing the right day and season

Weather matters more than it does on a land-based sightseeing tour. The experience requires good weather, and a cancellation caused by poor conditions brings a choice of another date or a full refund.

A sunny day should give you the best chance of enjoying the water color and underwater view. Spring has a practical advantage too. One family outing found the timing pleasant because the weather was good and the area was less crowded than later in the season.

That does not guarantee a quiet boat in spring, but it is a useful guide. If you can choose your date, I would favor a period outside the busiest summer weeks. You may still see school groups or large parties, so ask about the sailing load when possible.

The cancellation terms are straightforward: cancel at least 24 hours before the start time for a full refund. Changes or cancellations made less than 24 hours before departure are not accepted for a refund. The local time at the destination controls the deadline.

The experience also requires a minimum number of participants. If that number is not reached, the operator may offer another date or experience, or return your money.

Who will enjoy this most

I would recommend this trip to families who want a short, easy outing with a little variety. The combination of boat views, fish watching, a scenic cove, and possible swimming gives children several things to anticipate.

It also suits couples or solo visitors who want a quick look at the Cap de Creus coast without arranging a private boat. The scenery is the strongest reason to go, particularly if you value protected coves and undeveloped shoreline.

You may want to skip it if you need a quiet, uncrowded cruise, a long swim, or serious underwater viewing. The boat can hold 200 people, the underwater windows may be small, and your viewing time depends on the group schedule.

I would also think carefully about the nudist beach designation. Some people will see it as part of the cove’s natural, relaxed character. Others may find it unsuitable for their group. Knowing this before departure prevents an awkward surprise.

Should you book the Cala Murtra boat trip?

Book it if you want an affordable 90-minute introduction to the Costa Brava by water, especially with children. The protected cove, pine-covered cliffs, clear water, and simple underwater viewing make this more interesting than a basic harbor cruise.

Go with realistic expectations. You may share the catamaran with a large group, wait for your turn at the windows, and get only a short look at the fish. The trip is best understood as a scenic family outing with an underwater extra, not as a dedicated snorkeling tour.

If you choose a day with good weather and fewer large groups, the experience should have its best chance to match its promise. For the price, Cala Murtra offers a pleasant way to see a wilder side of the Roses coast without committing an entire day.
