Diving Center
La Sirena

Our diving centre is located in a Natural Park at the heart of the Costa Brava. It was founded in 1969 by Joaquim Suñer, among other partners, and has become well known for its effective organisation, comfortable facilities as well as customised service to meet every client’s needs.
We currently rely on three essential pillars which are awareness, learning and fun. These three objectives are present in all our activities as we believe that diving is a marine conservation tool that allows us to have a positive social impact.
Our four ships are fully equipped, ensuring a pleasant and comfortable experience: hot showers, elevators, plenty of space...
We offer all necessary rental equipment to enjoy both diving and snorkelling.
We also have a shop where you can purchase diving equipment, accessories and souvenirs.
Divers can enjoy accommodation with our collaborators: Flamingo Hotel and Camping La Sirena. The campsite is a relaxing place fit for visitors with showers, a cleaning area and storage for equipment, training rooms for courses and meet-up spaces for post-dive gatherings.
