Oregon Coast Aquarium is just e. of US 101 at the s. end of Yaquina Bay Bridge at 2820 S.E. Ferry Slip Rd. Visitors can experience the ethereal magic of jellyfish and the magnificent colors of the many varieties of fish, and watch sea otters, harbor seals and California sea lions in a habitat that replicates Oregon's rocky shores. You'll find one of the largest outdoor seabird aviaries in North America, whose residents include tufted puffins, common murres and graceful pigeon guillemots. Around the corner is a rocky den, home to a giant Pacific octopus.
The Aquarium's 1.32-million-gallon Passages of the Deep exhibit is an underwater adventure featuring 5,000 sea creatures where visitors can journey through shark-filled water in the safety of a 200-foot acrylic walkway nestled deep beneath a simulated sea.
