1 Best Sight in North County and Around, California

SEA LIFE Aquarium

Offering an educational and interactive underwater experience, the walk-through exhibits focus on creatures found in local waters including California lakes and streams and the cold-water marine animals that live along the California coast. Other exhibits include an underwater acrylic tunnel that affords a deep-sea (but dry) look at sharks, fish, and invertebrates. There's a seahorse kingdom, interactive tide pools, and jellyfish discovery. This park has a separate admission from LEGOLAND, although you can upgrade your LEGOLAND ticket to include the aquarium.
