Submarine Force Library & Museum 1 Crystal Lake Road, Groton, CT 06340

"The museum was cool but the actual submarine was closed due to malfunctioning ventilation and has apparently been closed for months. It's not supposed to reopen until some time in 2024. Would be nice to see that on a website or something. The displays were informative and all pretty cool."

"We managed to made a stop early in the morning at this museum because my son is interested in submarines. The museum is very informative and no entrance fee. However it’s disappointed to find out that SSN 571 is not open due to maintenance! And they don’t even say when it could reopen! I wish they could simply put the reopen date on their website so that people like us could make a plan for revisit."

"I like this museum. Unfortunately the Nautilus was off limits due to a ventilation problem. They didn’t know when it would be fixed. I recommend calling first to see if the submarine is open to visitors."

"We popped in before leaving our long weekend vacation in Mystic and were happy we did. This museum is free but I highly recommend giving a donation since it helps with maintaining the attraction. The museum has lots of interesting and interactive exhibits that are great for kids and adults alike. My favorite part of the museum is going in an actual submarine and exploring its many rooms. I do want to issue a trigger warning to those who suffer from claustrophobia. The passages through the submarine are understandably narrow and there isn't a much room for people to pass each other. Additionally, the steps down are steep and doorways require lots of ducking (so if you are a larger individual this might be uncomfortable for you). I enjoy history and learning about these submarines was fascinating!"

"the museum and car parking is free. closed on tueasdays. you can enter in a real submarine. also it has a nice gift shop. love this place."
