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

A short sea outing can still feel big. This one pairs Medes Islands scenery with on-board glass-bottom viewing in a tight 1.5-hour loop. You get real coastal geography, plus time to look down at the water instead of just shooting photos.

What I like most is the small-group setup aboard Nuria, a 1942 Catalan fishing boat, with a limited crowd (around 20) so the trip feels personal. And I especially love the way the underwater world is built into the experience, with glasses on the floor in front of your seat.

One thing to consider: the trip is time-based, so if you want extra time staring at fish, you may feel the viewing windows are brief. Also, the optional swim only runs in summer when conditions allow it.

Key things to know before you go

• Glass-on-the-floor underwater viewing right in front of your seat, so you do not need goggles or a whole extra activity.
• Nuria’s 1942 fishing-boat feel, a more authentic small-boat experience than big tourist craft.
• Caves and coves with guided narration, plus the chance to see the interior of a cave when conditions and piloting allow.
• Montgrí Natural Park photo stops and short land moments, with scenic views along the way.
• Summer swimming (10 minutes) in clear water from mid-June to September if the weather cooperates.
• Medes Islands time for a walk and marine-life viewing, followed by more glass-bottom viewing.

Why this 1.5-hour Nuria boat trip works from L’Estartit

L’Estartit is one of those Costa Brava bases where you can do a lot with very little time. This trip is only about 1.5 hours, which means you can fit it between beach time, lunch, or a bigger day trip.

The big win is that the experience is layered. You are not only cruising the coast. You are also watching the underwater side of the story, through glass panels placed where you sit. That turns the boat ride into something you can do with your eyes, your camera, and your curiosity all at once.

Meeting in Port de l’Estartit, then boarding the 1942 Barca Nuria

You start at Port de l’Estartit, at the beginning of the harbour area near Passeig Marítim. Walk the promenade toward the end, look for a small playground and information kiosk, then turn right after the last kiosk. You should see the fishing boats and the one marked on a white board that says BARCA NURIA in red.

Once you board, the vibe is different from typical day-tour boats. Nuria was built in the beach area of L’Estartit in 1942, so you get a more local feel, and the crew keeps it moving at a pace that supports frequent viewing and scenic stops.

If you are trying to time photos, arrive early and get settled quickly. The glass panels are positioned so you can watch without changing seats, which is easiest when you are not scrambling right at departure.

Montgrí Natural Park from seat level: glass-bottom time that actually matters

Montgrí Natural Park is the kind of coastal landscape that looks good from land and gets even better from water. On this tour, you get a mix of ways to see it, including a glass-bottom boat ride component and on-water viewpoints.

The glasses placed on the floor are the heart of the “look longer” part. Rather than treating underwater life as an occasional surprise, the layout encourages you to scan while the boat passes over shallower areas. You can watch marine life as the scenery rolls by, and you can do it even if the light is changing, because you are not relying on spotting everything from the deck.

What I like here is that it lowers the barrier. You do not need snorkeling skills or extra gear. You just need patience and a willingness to watch the water like it is part of the show.

Photo stops, cave passages, and the short stops that set the rhythm

This trip is built around a sequence of photo stops, visits, and scenic cruising moments, including multiple “breaks” where you can get a better look at what is around the next bend. You also get guided narration in Catalan, English, Spanish, and French, so you are not stuck with guessing games about what you are seeing.

One detail I pay attention to on any cave route is piloting and timing. When conditions are right, the boat can get into cave spaces, which makes the experience feel more than just driving past rock. The cave passage is also one of the moments where you may feel the sea movement more, so if you are sensitive to waves, consider bringing something for motion comfort.

Pace-wise, the trip is efficient. That is good if you want a complete “hits list” without a long day. It is not perfect if you love slow watching. There are moments to focus on marine life, but the schedule is tight, so you will not get endless time in one spot.

The Medes Islands: walk time plus underwater viewing

Then comes the part most people picture when they plan this area: the Medes Islands. Here you typically get a combination of walk time and marine life viewing, plus additional glass-bottom viewing.

The reason the islands work so well in a short itinerary is simple. Even without a full-day landing, you get the sense of protected coastal waters. You also get multiple ways to see life below the surface, first from the route and then from viewing time.

If you are a photographer, keep your settings simple. Between moving water and changing reflections, you get your best results when you focus on short bursts rather than long exposure attempts. If you love nature quietly, this is a good moment to slow down. Watch how the boat positions you for viewing, then take a breath and let your eyes adjust.

Swim in Montgrí (summer only), and what to expect when it is not swim season

One of the standout perks is the chance to swim in clear water in Montgrí Natural Park. This is offered from 15 June through September (with the end date depending on local timing), and only when weather conditions allow it. When swimming is running, you get about 10 minutes in the water.

This is not a long snorkeling session. It is more like a quick reset, a way to experience the water directly after watching it from the glass. In summer, that short swim can make the whole tour feel more personal, because you go from observing to being in the environment for a moment.

In spring and autumn, the focus shifts toward quiet coves and a calmer feel along the coast. You still get the cruise, scenic views, and cave and cove passing, but you should not plan your day around swimming unless the season and conditions match.

Price and value for a small-group sea outing

At about $28 per person for a 1.5-hour trip, this is priced like an experience, not a transport service. The value comes from three things you often do not get together at this price point:

• A small group (around 20 passengers), which keeps time on board more comfortable.
• Multiple viewing modes, especially the glass-bottom element.
• A route that includes both Montgrí Natural Park and the Medes Islands, with cave and cove passages.

You are paying for convenience and access. If you tried to recreate this on your own, you would be juggling boats, timing, and finding good viewing areas. Here, the experience is packaged into a short window, with the underwater viewing built in.

The only “value” risk is your priorities. If you mainly want a long land excursion or a full-day snorkeling-style adventure, this will feel short. If you want sea views, caves, and underwater viewing in one tidy block, it is a strong deal.

Who should book this, and who might want a different plan

This trip is a great fit for people who:

• Want a time-efficient way to experience the coast from L’Estartit
• Like marine life and want easy underwater viewing without extra gear
• Enjoy boat routes with scenic stops and a guided narrative in multiple languages
• Prefer small-boat comfort over large crowds

I would be more selective if:

• You get easily seasick, since cave passages and sea conditions can add movement
• You want maximum “watching time” of one area, because the tour is designed to cover several segments in a short window
• You are visiting outside the swim season and were hoping for a quick swim every time

Should you book the boat trip to the Medes Islands and NP caves?

Yes, you should book it if you want a compact, well-shaped nature experience from L’Estartit: coves, caves, Medes Islands scenery, and glass-bottom underwater viewing in about 90 minutes. The small-group feel aboard Nuria adds a layer of comfort that makes it more than a checklist activity.

If you are traveling in summer and weather cooperates, the Montgrí swim can be the cherry on top. If you are traveling in spring or autumn, you are still likely to enjoy the calmer coves and the coast-focused pacing.

Just go in with realistic expectations: this is not an all-day marine safari. It is a smart, scenic, seat-level way to see why this part of Catalonia is famous for its waters.
