About Creuers Mare Nostrum
We are a Costa Brava-based company specialized in glass-bottom boat excursions.
Discover the Costa Brava from a unique perspective with our glass-bottom boat trips. Sail through natural areas such as the Medes Islands and Cap de Creus and observe marine life through the underwater viewing windows of our catamarans.
An original, comfortable experience for all ages, perfect for enjoying the sea in a different way.
A beautiful walk to admire this coastline, so difficult to reach via the coves and beaches in the middle of August!
I highly recommend it.

A pleasant walk to do with the family.

It was a really lovely and relaxing tour. The glass-bottomed doors only open during the trip, and the flow of passengers is very relaxed. So nobody needs to arrive much early to secure a spot. Anyone expecting Caribbean fish won't find it here 😂 But everything was great and at fair prices.
