The park's remote location, its lack of search and rescue capability, and the distance from expert medical care require extra precautions:

• Solar radiation is intense!
• Wear sunglasses, sunscreen, a hat, and protective clothing.
• Carry insect repellent.
• Always snorkel with a partner.
• While on beach areas, watch for falling coconuts.
• Whatever beach you are on, be aware of the tidal movements and be alert for dangerous avas—tidal outflows from the reef. Their currents and undertows should not be underestimated.
• Coral rubble beaches are difficult to walk on; watch your step. Be especially careful of rocky areas, they can be slippery.
• Ask the visitor center about trail conditions.
• Never hike without water; carry 2 to 3 liters per person.
• Don't touch the coral! Cuts from coral take a long time to heal.
• Beware of dogs! People do get bitten.
• Medical treatment is available on Tutuila.

Health

There are few health risks of concern for normally healthy people visiting the islands. Bring necessary medications with you. Medical care is limited (even more limited on the Manu’a Islands). Though the LBJ Tropical Medical Center on Tutuila was once a highly regarded regional health center, now it has fallen on hard times with staffing problems and has only marginal services. Visitors with serious medical needs must receive care in Hawaii, Australia, or New Zealand.
