Cabo de Palos, on the southeastern tip of Murcia's Costa Cálida, is the gateway to the Reserva Marina de Cabo de Palos e Islas Hormigas — one of the most biodiverse marine protected areas in the western Mediterranean. The reserve encompasses volcanic rock formations, submerged cliffs, and reef walls descending to around 40 metres, creating rich habitats for grouper, moray eels, octopus, sea horses, scorpionfish, and dense schools of barracuda. Water visibility regularly exceeds 20 metres during summer, making every descent a vivid experience.
Boat dives depart from the small fishing harbour of Cabo de Palos, roughly 55 km south of Murcia city. Centro de Buceo Islas Hormigas operates scheduled departures to the reserve's key sites: El Bajo de la Campana, La Hormiga Sur, and the volcanic Las Islas Hormigas islets, where stronger current pockets attract eagle rays and pelagic species. Certified divers with at least a PADI Open Water qualification join boat dives; first-timers can book a Discover Scuba Diving introductory session that includes confined-water practice followed by a guided shallow reef dive.
Full equipment hire — BCD, regulator, wetsuit, and tank — is included in the dive fee. A 5 mm wetsuit is recommended from April through early June. Every session begins with a comprehensive safety briefing covering hand signals, emergency ascent procedures, and site-specific current behaviour near the southern islands. The centre carries a rescue oxygen kit on board and coordinates with Cartagena maritime rescue services in any emergency.
Water temperature peaks at 22–26 °C from July through September; winter dives are possible at 16–18 °C but require a dry suit. The reserve's commercial fishing ban has allowed fish populations to recover to exceptional densities. Prices run from €45 for a standard guided reef dive to €80 for deeper technical sites. PADI courses from Open Water to advanced levels are available as multi-day packages. The reserve's proximity to the Cartagena industrial port means that water clarity is somewhat lower on the port-facing north side; the open-sea southern sites offer the best conditions.

- Book boat dive slots at least two days ahead in July and August — the reserve is popular and departure places fill quickly.
- Request a 5 mm wetsuit when booking for April and May sessions — hire stock is limited and can run out.
- Early morning departures (9 AM) offer the calmest surface conditions and the best natural light for reef photography.
- GoPro cameras can be mounted to the tank strap — confirm camera attachment options with the dive centre when booking.
- Non-divers accompanying the group can hire snorkel gear and explore the shallows around the port breakwater.
- Strong easterly levante winds can suspend open-sea diving — ask about the cancellation and rescheduling policy before booking.
Frequently asked questions
Do I need a PADI certification to dive at Cabo de Palos?
Independent divers joining scheduled boat dives need at least a PADI Open Water or equivalent certification. Beginners without a qualification can book a Discover Scuba Diving session, which includes confined-water practice before a supervised reef dive.
What marine life is typically encountered in the reserve?
Common sightings include grouper, moray eels, octopus, sea horses, and schools of barracuda. Eagle rays and the occasional loggerhead turtle pass through the deeper sites near the southern islands in summer.
Is the diving suitable for children?
PADI Junior Open Water certification is available from age 10, permitting supervised dives to 12 m. Introductory sessions are offered from age 8. Parental consent forms are required for all participants under 18.
What happens if the weather is poor on the dive day?
Strong easterly levante wind can make exposed sites unsafe. The operator either moves to a sheltered alternative site or offers a rescheduled date without cancellation penalty. Check conditions before travelling from Murcia.
Is parking available at Cabo de Palos?
A public car park near the port entrance is free in winter and charges a small fee from June through September. Cartagena, roughly 20 km northwest, also connects to the village by regional bus.
