The Out Islands, the Exumas among them, have lower crime rates than Nassau and Grand Bahama, according to the UK Foreign Office, though petty theft and drink spiking rise during regattas and festivals; lock rental houses and keep an eye on your drink.

The pigs are large animals and can be pushy when food is about, so keep fingers clear and follow the guide. The nurse sharks at Compass Cay are wild animals; do not grab or corner them, and never get into water that has been baited. Sun and dehydration are constant risks on all-day boat trips. Emergency medical facilities on the Family Islands are limited, and serious cases are flown to Nassau or Miami, so travel insurance with medical evacuation matters.
