Our nurse editor's notes
- Snorkel with a buddy and stay inside the reef unless you are a strong swimmer; currents outside the reef can be strong.
- Do not stand on or touch coral. It harms the reef and can cut you.
- Protect your skin with a rash guard and a mineral sunscreen, and drink water; there is little shade on the sand.
