The water on the island is safe to drink and tastes much like our own water (and unlike the water in Spain!) although you should take the usual hygiene precautions that you would take anywhere where sanitation may be an issue. It is recommended that you are current with your tetanus and polio inoculations and I also had hepatitis A and typhoid jabs just to be sure. Malaria is not a problem. Neither my husband or I had any health problems whilst away but care should be taken if you are not in a first class resort.
