Grunion Run

Get Ready for a True Southern California Experience 

Watch hundreds of small silver fish called grunion ride the waves on to La Jolla beaches to spawn. Our naturalists will highlight the fascinating lives of these mysterious fish, help you hatch grunion eggs before your eyes, and then lead you to the beach to search for grunion in the wild. 

Prepare for cool, wet, nighttime conditions and bring a flashlight. Minors must attend with a paid adult, recommended for ages 6+. Pre-purchase required.
