Snorkelling: Complete Guide

The Costa Brava is one of the most spectacular snorkelling destinations in the Spanish Mediterranean. With its crystal-clear waters, abundant marine life and stunning underwater landscapes, L'Estartit has become the region's snorkelling epicentre. From beginners to experts, everyone can enjoy the underwater beauty of this area. In this guide we show you the best places to snorkel, what to expect, and practical tips to make the most of your experience.

Best Coves for Snorkelling on the Costa Brava

Cala Montgó (South of L'Estartit)

Cala Montgó is a wide cove with calm waters at the end of the Montgrí Natural Park between L'Estartit and L'Escala. Its sheltered waters make it ideal for snorkelling, especially on Tramontana wind days. The rocky bottom is perfect for exploring, with underwater caves and crevices harbouring diverse marine life. Rock fish, octopus, starfish and abundant marine flora make this cove unmissable.

Cala Pedrosa (North of L'Estartit)

Cala Pedrosa, north of L'Estartit, is known for its exceptionally clear waters and spectacular underwater scenery. It can be reached on foot via a long path through the park or by boat. It is exceptionally quiet due to its narrow geography and the small Pedrosa Island that protects it from north and east winds. Snorkelling here reveals a wide variety of fish, crustaceans and sea urchins. Less crowded than others, it is perfect for a quieter experience.

Cala Calella (Rocky Area)

Cala Calella is another snorkelling gem on the Costa Brava. Its underwater rock formations are home to a wide variety of Mediterranean fish, including white seabream, gilthead bream and more. Ideal for those seeking a more adventurous snorkel with varying depths.

Illa del Dui

Illa del Dui is a small islet close to the coast, set against spectacular rocky cliffs. This more exposed formation means fewer days a year allow calm snorkelling. Children will love this area full of small caverns and caves.

Water Temperature and Best Season

Water temperature varies significantly throughout the year:

• Winter (Dec-Feb): 12-14°C – Cold water, 5-7mm wetsuit required
• Spring (Mar-May): 14-18°C – Cool water, 3-5mm wetsuit recommended
• Summer (Jun-Aug): 22-26°C – Warm water, ideal for snorkelling
• Autumn (Sep-Nov): 18-22°C – Mild water, light wetsuit optional

The best season for snorkelling is June to September, with warm water and excellent visibility. However, April-May and September-October are also great, with fewer tourists.

Practical Snorkelling Tips

Equipment Needed: Mask, snorkel, fins and wetsuit (depending on temperature). Dive centres provide all equipment.

Safety: Never snorkel alone, respect warning flags, stay close to the coast and wear a life vest if you're not a strong swimmer.

Best Time: Early morning (8:00-11:00) offers fewer people, clearer water and excellent light.

Environmental Protection: Don't touch marine life, use eco-friendly sunscreen and don't feed the fish.

Conclusion

Snorkelling on the Costa Brava offers an unforgettable experience of connection with marine nature. Whether in the calm waters of Cala Montgó or exploring the spectacular rock formations of Cala Calella, each spot offers its own underwater magic. Get prepared, respect the environment, and enjoy a captivating underwater adventure.
