MoBay Undersea Tours
Montego Bay, Jamaica

Not a true submarine but actually sort of a deep glass-bottom boat with portholes, this is a fun and educational attraction that's a must especially if you're not a scuba diver or snorkeler.

A short walk down the stairs and you'll be in the glass hull surrounded by viewing windows that look onto MoBay's Marine Park. Sponges, corals, numerous fish, (even a few turtles during our visit!) make the ride spectacular.

One thing we really liked about this tour: you're free to head up on deck at any point, great for anyone who's worried they might be claustrophic (or who is traveling with a restless child).
