Going Great White Shark Diving in South Africa and more specifically a trip on the Slashfin, is a combination of goosebump thrills, education and relaxation on a luxury boat in the company of experienced experts and researchers! They will show you how to distinguish between a male and female shark and how to identify a specific shark by its unique dorsal fin and scars. The 20 – 25 minute boat trip to where the activity is to take place, is by itself an exhilarating adventure.
