Scorpion Submarine, Long Beach

I like so much this museum, we visit in the 2008, but some people say in 2014 that submarine its closed

LOVE this tour of the infamous "Scorpion" Russian submarine. You can tour it at your own pace, checking out the cramped quarters, even sitting down at the officers table. There is some great history here, so bring your camera and enjoy taking pictures of old school uber complicated guages, levers and dials. And check out how small that bathroom was - wow! Pro tip - the submarine is tight inside, and requires you to be pretty flexible to crawl through some spaces. If you've got some physical challenges, be aware that some parts of the sub can prove tough to get through.
