What Travellers Say
Reviews Summary
Visitors rave about the Columbretes Islands as a fantastic nature reserve, particularly for divers and those seeking tranquility. The abundant wildlife, both above and below the water, and the unique volcanic landscape are major draws. However, some find the sea journey can be rough, and securing diving permits requires advance planning.
"Spectacular excursion departing from the Port of Castellón. A great day to see wildlife and swim in an idyllic setting. Volcanic islands where we were able to observe the local endemic lizard, falcons, groupers, flying fish, and we were even lucky enough to see dolphins along the way! We saw Grossa Island, where we landed, had an explanation, and climbed the lighthouse, with a swim from the boat included!
You don't need anything other than food, drinks, a swimsuit, binoculars, and a diving mask.
A great day. Highly recommended, provided the weather and sea are good.
Thank you"

"Fantastic place to visit, recommended for divers and very quiet. A recommendation is to call for diving permits before going, in my case I was guided by the divers that Google said and when I arrived I found other requirements, call first before getting diving insurance"

"A fantastic nature reserve.
We went diving there and it was great.
We went on a sailboat and spent the night there. The area is very peaceful and there's lots of marine life.
We took a boat tour of the island.
On the way back, we were accompanied by dolphins for a while on the way to shore.
We went with Sedna Dive and it was a fantastic weekend."
