There is no one-size-fits-all answer to this question, as the safety of swimming and snorkelling with Tiger Sharks depends on a variety of factors, including the size and behaviour of the sharks in question. However, generally speaking, swimming and snorkelling with Tiger Sharks can be safe if you take certain precautions, such as staying close to a boat or other form of shore protection, and avoiding unnecessarily provocative behaviour around the sharks. It is always important to remember that interactions with any wild animals should be approached with caution.
