Pearl-Harbor

The battleship where Japan formally surrendered in 1945, moored on Ford Island and open to walk through from the teak deck down into the ships interior. Kids stand on the surrender deck, sit in the wardroom, climb up to the bridge and look down the sixteen-inch gun barrels. Guided tours go below into crew quarters and the engine spaces. Large parts are enclosed which makes it workable in rain, though the main deck is open. Reached by the Ford Island shuttle from the Pearl Harbor visitor center.

Two working seaplane hangars on Ford Island that still carry bullet holes from December 7, 1941, filled with restored aircraft from that day forward. Kids see a Japanese Zero, a B-25 bomber and Cold War jets up close, plus a restoration shop where volunteers work on planes in view. Flight simulators let older kids fly a mission and are usually an extra ticket. The setting does most of the work here because you are standing inside the actual buildings. Reached by shuttle bus from the Pearl Harbor visitor center.

A real World War II submarine you go down inside and walk through end to end, which is the kind of thing kids talk about for years. The passages are genuinely tight, the bunks are stacked beside torpedoes, and an audio tour explains what life aboard was actually like. An adjoining indoor museum holds torpedoes, a Poseidon missile and submarine artifacts. It is at the Pearl Harbor visitor center so it slots in alongside the memorial and aviation museum. Not suitable for strollers and small kids need to manage steep ladders.
