How long are submarine tours?

Submarine tours are approximately 40 to 50 minutes long.

Is it difficult to navigate the submarine?

The USS Blueback is a truly unique space at OMSI, but it can be challenging to navigate. Visitors must pass through a small, watertight door to enter the submarine, which requires some bending and stooping. There is a practice door you can try in the OMSI Lobby. Submarine visitors must be able to climb through through the lobby hatch in order to participate in the tour.

The submarine has stairs and is narrow in places. Wheelchairs, strollers and walkers are not allowed on the submarine. Canes are permitted. Closed-toe shoes are recommended.

Please note: The submarine has very steep stairs. Visitors must be able to self-navigate. Carrying children is not allowed.

Are there accessibility resources for the submarine?

The submarine has many informational panels with Braille text. Please contact a submarine staff member with questions or for additional support.
