In an underwater adventure. visitors are immersed in Keiko’s former home through acrylic tunnels surrounded by several feet of sea water. Passages of the Deep has proven to be an unique attraction. As though they were taking a walk into the open ocean, visitors are able to come face to face with large sharks, rockfish and bat rays swimming above and below. Waves surging against the tunnel gives visitors the impression they are beneath the ocean. And the Oregon shipwreck resting on the bottom increases the feeling of being early undersea explorers.
