Dangerous underwater inhabitants
Brochures abound with picturesque scenery, attractive images of young girls in swimwear on the palm-fringed, deserted beaches. The reality however is often different. Vacation can be marred by sunburn and insect bites, although divers are primarily concerned about aquatics and ponds polluting substances.

If you don’t want to wear a wet suit, use a thin lycra or even a pair of old pants and a t-shirt. They sachetat your skin from cuts, abrasions, coral and stinging jellyfish when diving and from sunburn when Snorkelling.
