Ilha de Currais in Southern Brazil features a combination of natural and artificial reef structures. Suitable for beginners, the site offers depths ranging from 5 to 15 metres with an average of 12 metres. Divers and snorkellers can expect mild currents and visibility between 5 and 10 metres. Access is by boat only, as the site is located 10 kilometres from the shore. Water temperatures fluctuate throughout the year, ranging from 19C to 28C. When navigating the reef, be aware of sharp coral, rocks, and the presence of stonefish. Always remain vigilant regarding boat traffic in the area and prepare for variable surge conditions.

Ilha de Itacolomis is a boat-access reef site located in Southern Brazil. The site features a manageable depth range of 5 to 16 metres, averaging 10 metres, making it suitable for beginner divers. Divers should note that the reef wall descends rapidly to 40 metres, requiring careful monitoring of depth and training limits. Conditions include mild currents, though visibility can vary significantly. The reef structure contains sharp coral and rocks, necessitating caution with buoyancy and hand placement to avoid cuts. Water temperatures fluctuate between 19 and 28 degrees Celsius throughout the year, so appropriate thermal protection is recommended. All equipment and supplies must be arranged via a boat operator prior to departure.

Balsa Espera Sete is a deliberately scuttled vessel located off the coast of Southern Brazil. Resting at depths between 23 and 27 metres, the wreck functions as an artificial reef in an open-water environment. Access is by boat only, situated over 40 kilometres from the shore. Conditions are variable, with visibility ranging from 2 to 30 metres and fluctuating currents. Due to the depth, potential for entanglement, and low-visibility risks, this site is suited for advanced divers with strong buoyancy control and wreck-diving experience. Divers should carry a surface marker buoy and a torch, and verify current conditions with an operator before attempting interior penetration.
