Columbretes Islands

The Columbretes Islands are made up of four groups of small volcanic islets: l’Illa Grossa, la Ferrera, la Foradada, and el Carallot. Together, they form one of Spain's most important natural and marine reserves.

The name of the islands comes from the Latin “colubraria”, given by the Romans due to the abundance of snakes they found upon arrival. For centuries, the archipelago was feared and avoided, becoming a refuge for pirates and smugglers. This helped to preserve its ecosystem almost untouched.

In the 19th century, the lighthouse on Illa Grossa was built to guide sailors. The waters surrounding the archipelago were once used for fishing, until its ecological value was recognized and the area was transformed into the protected paradise that can be visited today.

What to Do in the Columbretes Islands

The first part of the day trip begins with a guided tour of Illa Grossa, led by the park rangers. During the one-hour walk, you'll learn about the volcanic geology and the island's endemic flora and fauna. At the top of the ancient crater, you'll enjoy spectacular views of the lighthouse and the rest of the islets glimmering like diamonds over the ocean.

As you might expect, the true magic of the Columbretes lies beneath the waves. The best activities here are snorkeling and diving, with the seabed offering crystal-clear waters and breathtaking biodiversity.

It is important to keep in mind that there are no shops or cafes on the island, so you'll need to bring your own food and drinks for the day. In return, you'll experience a unique chance to connect with nature in its purest form and discover one of the Mediterranean's most majestic protected treasures.

Getting to the Columbretes Islands

When planning a trip to the Columbretes Islands, it’s important to keep in mind that access is regulated to protect the area. It’s recommended to book in advance to ensure you don’t miss out on a spot.

Boats to the islands mainly depart from Castellón de la Plana port, although during the high season, the trips are also available from Oropesa del Mar and Alcossebre.

The duration of the journey depends on the type of boat and sea conditions, but most trips take around 2.5 to 3 hours.
