War in the Pacific National Historical Park is a new and developing area and your safety and enjoyment are our main concern. You can ensure both by observing the following:

Do not enter any caves or tunnels. Some may contain hidden explosives. Do not open any sealed caves; it is illegal and dangerous.

Most important of all: Do not disturb any ammunition that you may find on or off shore. It is extremely dangerous and may detonate at any time. Report its location to a ranger, who will have it removed by qualified personnel.

War in the Pacific National Historical Park contains numerous World War II relics, including three Japanese coastal defense guns in the Piti Guns Unit (far left) and the miscellaneous remains of American military equipment sunk offshore during the July 1944 landings.
