About this spot
Sub Aqua is a dive site based at Karon Beach on Phuket's west coast. The site is accessible year-round, making it a reliable option for divers planning trips at any season. As a non-protected area, conditions can vary, but the site supports a range of marine species documented through community observations. The site has attracted 12 recorded species observations, indicating decent biodiversity for the area. Three community-contributed videos are available, giving divers a preview of conditions and wildlife. Current coral bleaching alerts suggest monitoring conditions before planning a trip; seasonal variations in water quality are common on this coast. Karon Beach itself is one of Phuket's most accessible dive entry points, with nearby facilities and boat access to nearby reefs. The shallow, sandy bottom near shore gradually transitions to deeper structure, offering options for different experience levels. Given the site's location on a popular public beach, expect moderate activity, especially during peak tourism months.
