Underwater views without getting wet. This catamaran trip pairs big Costa Brava scenery with the Medes Islands Marine Nature Park and its underwater viewing rooms. As you leave the Roses bay, you’ll spot the dramatic El Montgrí massif, often described like a sleeping bishop stretching toward the sea.

I especially like two things: first, the chance to glide along the coast for sightings and photos, including a pass by the Foradada cave (holed in Catalan) near Montgó Cove. Second, you get real time on land in L’Estartit for a town stroll, and if your trip lands on Thursday, the weekly market is on. The main drawback to plan around is weather, since this experience requires good sea conditions and the route can change if conditions shift.

One more practical note: the whole experience runs about 5 hours with a mobile ticket, and the group can be up to 200. If you’re sensitive to crowds or motion, you’ll want to pick your spot early and come ready for a bit of boat time.

Key highlights worth marking on your day

• Medes Islands Marine Nature Park with catamaran underwater viewing rooms focused on the seabed
• Foradada cave and Montgó Cove views along the coast, with chances for photos
• L’Estartit stop (about 1 hour 30 minutes), plus a Thursday weekly market
• A short pass/walk at Cala Montgó for coastline views (about 15 minutes)
• Return cruise through the Gulf of Roses, past L’Escala, Sant Martí d’Empúries, San Pedro Pescador, and Empuriabrava
• Up to 200 travelers and a mobile ticket, so timing on deck matters

Sailing over the Roses bay and El Montgrí’s “sleeping bishop”

Right away, this trip is about the view from the water. You cross the bay of Roses with El Montgrí looming in the background, and it’s easy to see why locals describe it like a sleeping bishop. Even before you reach the Medes Islands, the route gives you that classic Costa Brava feeling: sunlit coves, layered coastline, and the sense you’re going somewhere that’s hard to reach by land.

What I like here for your day plan is that you do not need to rush around. You’re moving, but you’re not scrambling. This part works well if you want a relaxing, scenic outing instead of a full-on sightseeing grind.

One thing to keep in mind: boat days feel long in a good way, but the schedule still matters. With about 5 hours total and only a limited chunk of time on land, treat the deck as your main “attraction time.”

Foradada cave and Cala Montgó, built for quick photo moments

As you cruise past Montgó Cove, the operator points out the Foradada cave. In Catalan, Foradada means holed, and with a bit of luck you can spot small activity, like a boat crossing the opening.

Then comes the short land window: a walk/passage by Cala Montgó, around 15 minutes. It’s not a long hike. It’s a photo stop, a stretching stop, and a way to reset your eyes after time watching the sea from the catamaran.

Here’s how I’d approach it: do your best photo work early. The group moves, then the catamaran schedule continues. If you care about golden-hour lighting or you want a slower stroll, arrive with a plan to prioritize what you want most in those 15 minutes.

Medes Islands Marine Nature Park and the catamaran underwater viewing rooms

This is the star of the show. At the Medes Islands Marine Nature Park, you have access to the catamaran’s underwater viewing rooms. These are built so you can see the wild seabed without suiting up or getting wet. It’s a clever way to experience marine life while still staying on a stable platform.

Why this matters for your decision: the Medes Islands area is known for its protected marine environment, so the underwater rooms are a direct way to focus on what makes this coast special. Instead of just looking at water, you’re looking through it, straight down at rocks, seafloor texture, and sea life that you would otherwise miss from the surface.

What you should consider: underwater visibility can depend on conditions. If the sea is rough, you might not get the same clear view you’d hope for, and the rooms can feel busy since the group shares the same viewing time. If you want the best chance at a good look, be ready to reposition quickly when your turn opens up.

Also, remember this part is more about the underwater scenes than about standing on a beach. If you’re traveling with kids, this often lands well because it feels like science with a view.

L’Estartit (1 hour 30 minutes): market day and an easy town break

Once the catamaran reaches the port of El Estartit, you get time to step into town for about 1 hour 30 minutes. This is your chance to balance the day, since the first chunk is all about sailing and the marine viewing.

If your trip falls on a Thursday, that’s extra valuable. The town has a weekly market then, which gives you a reason to browse beyond beach snacks. You can wander streets lined with shops that lean into the local marine vibe, and you can look for seasonal, local food options while you’re there.

Practical advice for this stop: don’t try to do everything. In 90 minutes, you can either cover a few streets and find a good snack and photo spot, or you can do a focused market browse. Choose one priority. That way you leave feeling like you saw L’Estartit, not like you hurried through it.

Also, be mindful of timing when you’re on land. The boat schedule is fixed, and the day is designed around the return cruise. Set a mental alarm for when you should head back toward the port.

Cala Montgó to L’Escala and back through the Gulf of Roses

After the underwater viewing and the L’Estartit break, the return cruise is still part of the experience, not just travel. You sail back toward Roses through the Gulf of Rosas, passing familiar names and different coast flavors.

On the way back, you’ll go by L’Escala. Then you enter the gulf waters and pass the Greek port of Sant Martin de Empúries. After that, the route continues past San Pedro Pescador and the Empuriabrava area. The scenery also includes Robina beach and then reaches Santa Margarita and Roses.

This is one of those routes where the “where am I looking?” changes over time. You go from marine nature focus (the Medes) to classic coastal passes (coves, beaches, and ports). It’s not a history lecture with museum stops, but it gives you a moving overview of this stretch of Catalonia.

If you like variety, you’ll probably enjoy the rhythm. If you prefer a quiet day with fewer transitions, you might feel like the boat keeps moving, but you still get plenty to watch from deck.

Price and time: is $48.20 good value?

At $48.20 per person, this is priced like a full half-day experience. You’re paying for a catamaran ride, access to the underwater viewing rooms at the Medes Islands Marine Nature Park, and a structured return cruise plus the short photo stop at Cala Montgó.

Here’s my value check for your travel brain:

• If your main goal is underwater viewing without hassle, that’s a big part of the price, and it’s the most unique component on this route.
• If you only want beach time, this may feel a bit expensive because the land moments are short, especially the Cala Montgó stop.
• If you want a mix of sea views, a proper marine stop, and town time in L’Estartit, the price starts to make sense quickly.

In other words, you’ll get your money’s worth most if you genuinely care about the Medes Islands viewing rooms and you’re happy with a moderate amount of time on land.

Duration is about 5 hours, which is a sweet spot for many people. You still have time to eat in town afterward or continue exploring Girona-area sights the same day.

Best time to go, what to bring, and how to pick your spot on deck

This trip requires good weather, so plan around forecast confidence. On days with calmer seas, you’ll enjoy the experience more, especially when you’re spending time in and around the underwater viewing rooms.

What I’d pack for a comfortable catamaran day:

• A light jacket or layers. Even when it’s warm, sea wind can cool you down.
• Sunscreen and a hat. You’ll be out in open air for long stretches.
• Water and a snack for the trip gaps. You’ll have a town stop at L’Estartit, but it’s still helpful to stay comfortable between moments.
• Comfortable shoes. You’re not doing a long walk at Cala Montgó, but you do want stable footing during short stops.

How to pick your viewing spot:

• Get to a good deck location early, especially before the coast photo passes.
• During the underwater room access, move with the group flow. Staying stuck in one spot can mean missing the moment when your section gets clear access.

And if you’re traveling with service animals, this experience allows them, so you can plan your day with that in mind.

Should you book this catamaran trip?

I’d book this if you want a Costa Brava experience that feels special without being complicated. The underwater viewing rooms at the Medes Islands Marine Nature Park are the main reason to pick this tour, and the sailing route gives you enough scenery to make the time feel earned. The L’Estartit stop adds real flexibility, especially on Thursdays when the weekly market is running.

I would hesitate if your day is weather-sensitive or you already know you won’t enjoy being on a boat for about 5 hours. Also think about your tolerance for crowds since the group can reach up to 200, which can make shared spaces like the viewing rooms feel busy.

If you’re going with realistic expectations, this is a good value: a half-day outing that mixes coast views, marine nature access, and a town stop you can actually use.
