Keep an eye out for nudibranchs, octopus, and moray eels. The Posidonia seagrass meadows are home to a variety of smaller creatures and provide a nursery for many species.

Best Time to Visit

The best time to visit the Medes Islands for diving is generally from May to October. During these months, the water is warmer, the visibility is at its best, and the weather is more predictable. July and August are the busiest months, so consider visiting in the shoulder seasons (May/June or September/October) for fewer crowds.

What Makes It Special

The Medes Islands' protected status since 1983 has allowed marine life to flourish, making it one of the most biodiverse areas in the Mediterranean. The varied underwater topography, including caves, tunnels, and drop-offs, provides a unique and exciting diving experience. The "Tunnel de la Vaca" (Cow Tunnel) is a particularly famous dive site.

Practical Tips

Book your dives in advance, especially during peak season. Consider bringing a wetsuit of at least 5mm thickness, even in summer, as you may spend a significant amount of time underwater. Respect the marine environment; do not touch or disturb any marine life. Currents can be present, so be aware of your surroundings and follow your dive guide's instructions. Bring underwater camera to capture the amazing marine life.
