You can visit the Submarine USS Nautilus at the US Navy Submarine Force Museum in Groton, CT.

The admission is free and the tours were self guided with a wand-like radio device that broadcast a different narration for each area of the boat. The interior was pretty much spotless. Almost all the areas are walled off in plexiglas but there wasn't so much as a smudge on any of it. They must come in and clean it every night. It is a challenge for photographs with the reflection but most areas are well lit. The staff certainly had a sense of humor posing some of the dummies. The narration was well done and informative, and cut off sharply as you transitioned between areas. Unlike some other museums there are no tour guides and the staff on hand were unable to answer a few questions I had.

The museum building has periscopes visitors can use, a modern submarine helm center, various torpedoes and sub launched missiles, a replica of the Revolutionary War submarine Turtle, and a number of other interesting exhibits. In front of the museum are 4 minisubs - a Japanese Type A minisub of the type used at Pearl Harbor, the Experimental Sub SS X-1, an Italian Maiale minisub (the inspiration for the British Chariot), and the Swimmer Delivery Vehicle. There is also a full sized conning tower, a deck gun, and a ballistic missile hatch assembly.

There is a gift shop with a moderate selection of items, but oddly no Nautilus hats. There's no snack bar and the nearest food is on the Military Highway near 95. If you want to get there early there is no parking on site before the gate is opened - the gate is opened around 8:45. Check the museum's website for current hours. The sub has steep stairs and is not handicapped accessible.
