Each of the stops along the trail are unique because they showcase a number of different underwater sites including airplanes, landing craft, tanks, and ships.

These underwater sites represent wartime activities that added to Saipan's rich maritime cultural heritage.

Due to its deep waters and natural barriers against the forces of the ocean, the lagoon has been an important maritime resource since prehistoric times.

Mañagaha and the surrounding barrier reef form a natural breakwater making these waters an ideal haven for watercraft of all shapes and sizes.

A large number of ships designed for commercial use were commissioned by the Imperial Japanese Navy for military service as auxiliary forces.

Three US Sherman Tanks, located within swimming distance of Oleai and Susupe beaches, played a significant role in the initial invasion by US forces.

The three tanks are semi-submerged and are a prime attraction for both locals and tourists due to their striking nature with turrets above the water.
