El Bajo is a reef site located in the Gulf of Urabá, Colombia. This site is accessed by boat and offers depths ranging from 9 to 19 metres, making it suitable for beginners who are comfortable managing buoyancy in moderate currents. Water temperatures fluctuate between 24 and 28 degrees Celsius throughout the year. Visibility and current conditions can shift without warning, requiring divers to remain alert. Due to active boat traffic, the use of a delayed surface marker buoy is essential during ascents. The reef environment supports a variety of reef fish and invertebrates typical of the region.

The ARC Sebastián de Belalcázar is an artificial reef and shipwreck resting on a sandy bottom at a depth of 40 metres. The bridge structure sits at 25 metres, allowing for multilevel dive profiles. Access is by boat only, as the site is located 7 kilometres from the shore. Divers must be advanced to manage the depths, moderate currents, and potential hazards including entanglement and overhead environments. Penetration of the wreck is restricted to those with specific wreck diving certification. Visibility ranges from 10 to 30 metres, and water temperatures remain consistent between 27 and 29 degrees Celsius. A buoy line is provided for safety stops during ascent.

Northern Stones is a series of submerged rock formations that create several independent reefs. This site is strictly for advanced divers due to the depth profile, which ranges from 18 to 40 metres with an average depth of 24 metres. Access is exclusively by boat, and the site is characterised by moderate currents. Visibility typically ranges between 10 and 15 metres. Water temperatures remain consistent throughout the year, fluctuating between 27 and 29 degrees Celsius. Given the significant depth, divers should be mindful of the deep-water environment during their descent and exploration of the rocky topography.
