Overshadowed by SeaWorld and the zoo, this wonderful interactive nature center highlights the plants and animals native to San Diego Bay and the surrounding wetlands. Featuring exhibits of stingrays and small sharks in kid-level open tanks, the center's most recent addition is its $3-million Discovery Center, which is home to Turtle Lagoon, San Diego's only habitat for endangered green sea turtles. There are also large tanks with moon jellyfish, eels, and rainbow trout. CVNC is in Sweetwater Marsh, one of San Diego's top bird-watching spots. The nature center has walking trails and a facility for experiencing the bird life (including aviaries with shorebirds and raptors). The parking lot is located away from the center, and a shuttle bus ferries guests between the two points every 10 to 15 minutes.
