L’Estartit: Boat Trip to the Medes Islands and the NP Caves

Sea caves are best seen from the water. This 90-minute cruise from L’Estartit takes you aboard the Nuria, a small Catalan fishing boat built on the beach in 1942, for a close look at the Medes Islands, Montgrí Natural Park, and its rocky coves. I like the limited capacity of 20 people, and I like that the boat’s floor has viewing panels for spotting marine life below.

The price is reasonable at $28 per person, especially for a short coastal outing with several sights packed into one trip. The main caution is that the ride is fairly brief, and the guiding can be light. One recent French-language comment praised the friendly communication, while another said the scenery was excellent but offered little spoken explanation.

Key points to know before you go

• Nuria is a genuine 1942 fishing boat: This is a small, characterful vessel rather than a large sightseeing ferry.
• Only 20 passengers are accepted: The intimate size makes it easier to see the caves and use the glass-bottom viewing panels.
• The route combines three coastal highlights: You visit the Medes Islands, Montgrí Natural Park, and nearby caves and coves.
• A short swim is offered in warmer months: From June into September, weather permitting, you may get about 10 minutes in the clear water.
• The boat ride is scenic but not lecture-heavy: Expect views and close passes through caves, with less detailed commentary than on a formal nature tour.
• The best value comes from the setting: At $28, it is a good fit if you want a simple coastal trip rather than a full-day excursion.

Setting out from L’Estartit on the Nuria

Your trip begins at the Port de l’Estartit, at the start of the harbor. Follow Passeig Marítim toward the end, pass the small playground and information kiosks, then turn right after the last kiosk. The Nuria is beyond the fishing boats, marked by a white board with Barca Nuria written in red.

Plan to arrive about 15 minutes before departure. You can go directly to the boat if your reservation is already made, which keeps the start simple. Since the meeting point is inside the harbor rather than at a large terminal, allow a few extra minutes to find the correct pier.

The Nuria is the heart of this outing. Built on the beach at L’Estartit in 1942, it gives the ride a local, working-boat character. You are not boarding a large vessel with rows of seats and a fixed entertainment system. The capacity is limited to 20 people, so the mood should feel more personal and the boat can approach smaller coastal features more easily.

That small size also brings a practical tradeoff. A compact boat may feel more affected by waves than a larger cruise vessel. One October outing was still enjoyed despite noticeable swell, while another comment asked for longer periods to watch the marine life. If you are sensitive to motion, keep that in mind when choosing your departure.

Watching the sea through the glass-bottom panels

The boat has glass panels set into the floor in front of the passenger seats. These let you look below the surface while the Nuria is moving or paused near areas of interest.

This is one of the best features for families and anyone who wants more than a standard coastal cruise. You do not need to be in the water to get a glimpse of the marine reserve. The views will depend on water clarity, sunlight, sea conditions, and how long the boat remains near each spot, so you should treat the viewing panels as an added opportunity rather than a guaranteed underwater show.

The timing matters. A 90-minute trip has to cover several areas, including the park, caves, coves, and Medes Islands. You may get only a short window to study fish or the seabed. If marine life is your main reason for booking, pay close attention when the crew slows the boat and be ready to look down quickly.

The trip is conducted in Catalan, English, Spanish, and French. That is useful for a mixed group, but you should not expect a long natural-history talk. The strongest positive comments focus on the boat ride, the caves, the scenery, and the pleasant French communication. One particularly useful warning is that the experience may not include much detailed guiding. I would choose it for the views first, and the commentary second.

Cruising through Montgrí Natural Park

The Montgrí Natural Park provides the main coastal setting for the cruise. From the boat, you see the rugged shoreline, small coves, and rock formations that are difficult to appreciate from land. The route includes scenic viewing, photo stops, a guided element, and a glass-bottom boat ride.

The appeal here is the change of pace. You are not rushing between inland attractions or spending time on a bus. The shore passes slowly enough for photographs, while the boat gives you angles of the coast that are unavailable from the promenade.

The coves are especially appealing in spring and autumn. During those seasons, the trip is presented as a quieter way to enjoy the park, with fewer summer beach pressures. The exact feel depends on weather and sea conditions, but the seasonal timing may suit you if you prefer a calmer outing over a busy midsummer swim stop.

The caves add a little drama to the route. A recent French-language comment singled out the boat’s pilot for entering one of the caves, calling the passage particularly impressive. That is an important detail: the experience is not only an offshore cruise with distant views. The boat may take you close to, and in at least one case inside, a cave.

Still, conditions control what is possible. A boat cannot safely enter every formation in every kind of sea. Consider the cave section a strong possibility rather than a promise of a fixed number of cave passages.

The 10-minute swimming stop

From June 1 into September, and only when weather conditions allow, the trip may include about 10 minutes for swimming. The supplied information also describes the swimming period as running from June 15 through September, with the end date worth checking before you book. In practical terms, confirm the current seasonal schedule and remember that sea conditions can cancel the stop.

The water is described as clear, and the swim takes place within the Montgrí Natural Park area. This gives you a chance to connect with the setting rather than simply photograph it from the deck. You can look down into the water, cool off, and see the coast from a lower angle.

Ten minutes is a short stop. You will not have time for a long swim, extended snorkeling session, or a leisurely beach break. Think of it as a quick dip built into a sightseeing cruise. Bring what you need to swim comfortably, but do not organize your entire day around a lengthy water activity.

Outside the summer swimming period, the trip still runs as a scenic coastal outing when conditions and scheduling permit. In spring and autumn, the quiet coves are the main seasonal appeal. That makes the boat useful beyond the hottest months, even though the water stop may not be available.

Reaching the Medes Islands by glass-bottom boat

The Medes Islands are the final major highlight. This small island group is known for its protected marine environment, making it a natural place to combine above-water views with underwater observation.

The trip gives you two ways to appreciate the islands. You see the rocky shapes from the boat, then look through the glass panels for signs of marine life below. The island visit is not a long walk or shore landing. The itinerary describes marine-life viewing, a walk, and a glass-bottom boat ride, but the experience is fundamentally a short boat excursion rather than an island hike.

That distinction matters when you set expectations. You will not spend hours exploring trails or settling on a beach. Instead, you get a compact look at the islands as part of a wider coastal circuit.

The protected status of the waters is a major reason this stop feels worthwhile. Even if you see only brief flashes of fish or underwater rock, the reserve gives the trip a clear purpose beyond taking a ride for its own sake. For the best chance of seeing below the surface, sit near one of the floor windows and watch for moments when the boat slows.

What the short duration means for value

At $28 per person, this is priced as an accessible coastal excursion. You receive a 1.5-hour boat tour, a small group setting, views of the Medes Islands, access to the caves and coves of Montgrí Natural Park, and the possibility of a seasonal swim.

I think the price works well if you want a simple half-day addition to your time in L’Estartit. You are paying for the boat, the route, and the chance to see the coast from the water, not for a full marine expedition or a long guided lesson.

The value is strongest for three types of visitors. First, you get a good introduction to the coast if you have limited time. Second, it suits families or couples who prefer a short activity with several different sights. Third, it works for people who like traditional boats and local character more than polished resort-style cruises.

The value is weaker if your priority is extended swimming, serious snorkeling, or detailed nature interpretation. The boat ride lasts only 90 minutes, and the stop for marine-life viewing may feel rushed. One comment specifically wished for more time to observe sea creatures. If that is your main goal, a dedicated snorkeling or longer marine reserve trip may suit you better.

How much guiding should you expect?

The tour operates in Catalan, English, Spanish, and French, which is a useful language range for an international port town. The presence of a live guide suggests that you should receive some explanation during the route.

In practice, I would keep your expectations modest. The most favorable comments praise the friendly French communication and the pleasant manner of the guide. At the same time, one detailed assessment said the outing matched its advertised route but did not really include a guide or much information during the cruise.

That combination tells you what kind of experience this is. You are likely booking a scenic ride with some assistance and commentary, not a formal ecology lesson. The pilot’s skill near the caves may be more memorable than a long spoken presentation.

If you want facts about the islands and park, listen when commentary begins and ask questions if there is an opportunity. But choose this trip because you want to see the coast, not because you expect every rock and fish species to be explained.

Who will enjoy this boat trip most?

I would recommend the Nuria for people who want a short, friendly outing with strong scenery and a local feel. The limited group of 20 makes it more intimate than a large harbor cruise, and the old fishing boat adds character you will not get from a standard modern tour boat.

It is also a good choice if you want several experiences in one package: cave passages, coastal views, glass-bottom viewing, the Medes Islands, and possibly a swim. You do not need to commit an entire day, and the $28 price keeps the decision easy for most holiday budgets.

Families may like the manageable duration, especially if younger children lose interest on long cruises. The glass panels give children something specific to watch, though the amount of marine life visible will vary.

You should think twice if you need a long swim, a quiet luxury cruise, or a detailed scientific guide. The boat can encounter swell, the schedule is compact, and the commentary may be limited. Also, the swimming stop is seasonal and weather-dependent, so do not book solely for that feature without checking current conditions.

Booking, timing, and small practical details

You can reserve the activity and pay later, which helps if your plans around L’Estartit are still shifting. Cancellation is free up to 24 hours before departure for a full refund, according to the supplied booking terms.

Check available starting times before you choose a date. The meeting point is the harbor at L’Estartit, and you should be there 15 minutes early. Look for the white board with red Barca Nuria lettering after the last information kiosk.

The tour provider is Excursions Maritimes Nuria. Since the boat carries only 20 passengers, booking ahead is sensible during the summer period. The smaller capacity is one of the experience’s strengths, but it also means fewer spaces on each departure.

Weather deserves attention. The caves, swim, and underwater views all depend on sea conditions. A calm day should make the glass-bottom viewing and cave passages more enjoyable, while rougher water may shorten or change parts of the route.

Should you book the Nuria?

Book this trip if you want a reasonably priced, small-boat look at the Medes Islands and Montgrí coast. The old Nuria, the cave passages, and the glass-bottom panels give it more personality than a basic harbor cruise. The possible 10-minute swim is a pleasant bonus in summer, not the main event.

Skip it if you want hours in the water or a detailed guided study of marine life. For everyone else, this is a practical way to see several coastal highlights in 90 minutes, with enough local character to make the short trip feel worthwhile.
