Arrecife is a reef site located off Mataro, Spain, accessible only by boat. The site reaches depths of 23 metres and is suitable for intermediate divers. Divers should expect moderate currents throughout the dive, which can intensify depending on tidal conditions. Due to active boat traffic, the use of a surface marker buoy is essential, and divers must maintain awareness while surfacing. Species recorded around this area include common octopus, Mediterranean moray, wrasses, scorpionfish, various nudibranchs, and sea stars. Visibility is variable, and conditions should be confirmed with a local operator prior to departure.

Jabugo is a boat-access reef located off Mataro, Spain, featuring a profile that descends from the shallows to a maximum depth of 36 metres. Due to the significant depth, this site is suited for advanced divers who can manage nitrogen levels and monitor computer profiles closely. The reef topography includes crevices and ledges that provide shelter for conger eels, moray eels, and lobsters, while rockfish and nudibranchs are found across the rockwork. Conditions include mild currents and variable visibility. Water temperatures fluctuate between 13C and 20C throughout the year, necessitating a well-fitted wetsuit or drysuit. Divers should deploy a delayed surface marker buoy before ascending to ensure visibility to the boat crew.

El Foro is a reef site located off Mataro, Spain, that descends to a maximum depth of 38 metres. Due to the significant depth, this site is suited for advanced divers who can maintain strict buoyancy control. Access is exclusively by boat, and conditions such as visibility and currents are variable. Divers should monitor their depth gauges closely throughout the dive. Water temperatures fluctuate between 13C and 19C depending on the time of year, necessitating appropriate thermal protection. As facilities are not confirmed at the site, ensure all air fills and equipment checks are completed before departing from port.

La Hispaniola is a deep wall dive located off Mataro, Spain. The site features a vertical rock face that drops from 30 to 45 metres, making it suitable only for expert divers. Conditions are variable, with visibility ranging between 10 and 30 metres and currents that can shift during the dive. Due to the significant depth, divers must maintain strict monitoring of gas reserves and decompression requirements. Access is exclusively by boat. Divers should carry a surface marker buoy and deploy it prior to ascent, particularly in areas with boat traffic. A redundant air source and a dive computer capable of managing deep-dive profiles are strongly advised for this technical environment.

El Dorado is a reef site located in Mataro, Spain, reaching depths of up to 22 metres. The site features a rocky substrate and reef structure that requires careful navigation due to variable visibility. Divers should expect mild currents, making buoyancy management relatively straightforward. Given the range of water temperatures from 13C to 24C, divers should select appropriate exposure protection based on the season. As facilities are limited, it is essential to confirm boat logistics and equipment availability with a local operator before arrival. Always carry a surface marker buoy, as surface conditions can change between dives.

El Muro is a wall dive located in Mataro, Spain, featuring a vertical structure that descends to a maximum depth of 23 metres. The site is suited for advanced divers due to the presence of moderate currents and the requirement for boat access. Divers should maintain solid buoyancy control and situational awareness throughout the dive. Water temperatures fluctuate between 13C and 23C depending on the time of year. Because of active boat traffic in the area, it is essential to deploy a surface marker buoy before ascending and to remain close to the wall during safety stops to ensure visibility to passing vessels.

L'Ancora del Negre is a wall and reef site located off Mataro, Spain, offering a deep-water experience for advanced divers. The topography features a rocky wall that descends to depths between 25 and 35 metres. Due to the significant depth, divers must maintain strict buoyancy control and adhere to decompression limits. Access is exclusively by boat, and conditions such as visibility can be variable. Divers should monitor their depth gauges closely throughout the dive to manage the primary hazard of depth. The site is suited for experienced divers capable of managing deep-water protocols in mild current conditions.

Reyes is a reef dive located 3000 metres offshore from Mataro, Spain. The site features a reef structure situated between 21 and 26 metres, with an average depth of 25 metres. Due to the depth, this site is suited for advanced divers who can manage decompression limits and buoyancy control. Access is by boat only, and the site experiences mild currents. Visibility is variable, ranging from 6 to 30 metres. Water temperatures fluctuate significantly throughout the year, from 13C in winter to 23C in summer. Night diving is permitted at this location. Local facilities include air fills, equipment rental, and guided tours.
