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.

Montseny is a reef site located off Mataro, Spain, accessible only by boat. The topography drops from the surface to a maximum depth of 27 metres. Divers encounter a mild current, making navigation manageable for those with intermediate experience. The site features a complex reef structure with crevices and sharp rock edges that require careful manoeuvring. Due to the presence of heavy boat traffic in the area, the use of a surface marker buoy is essential for all ascents. Water temperatures fluctuate between 13C and 23C throughout the year, necessitating appropriate thermal protection based on the season.

Los Cubos is an artificial wreck site located off Mataro, Spain. The structure sits at depths reaching 25 metres, requiring advanced diving skills. Access is strictly by boat, and divers must remain vigilant regarding active boat traffic when surfacing. The site features mild currents, though visibility can shift significantly depending on local conditions. Divers should maintain precise buoyancy control to avoid contact with the artificial structure. Due to water temperatures ranging from 13 to 23 degrees Celsius, appropriate thermal protection is recommended, particularly during the cooler months. The wreck environment demands careful monitoring of depth gauges throughout the dive.

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.

El Santuario is an artificial wreck site located off the coast of Mataro, Spain. The site reaches a maximum depth of 23 metres and is accessible only by boat. Divers encounter mild currents and variable visibility, requiring careful buoyancy control and awareness of wreck penetration hazards.
