Become a Junior Ranger!

After a five-year break, “Junior Rangers” is back at the Tijuana River National Estuarine Research Reserve (TRNERR). Junior Rangers gather at more than 70 California State Parks from the redwood region, to the high sierras, to the sunny Southern California beaches. Children ages 7 to 12 are invited to take part in this exciting program, designed to help them discover the rich natural and cultural heritage preserved in parks.

At TRNERR, the Junior Ranger Program takes place every Thursday from 3:30-4:30 p.m. with different topics presented at each session. Estuarine ecology, natural and cultural history, plants, and wildlife are among the subjects likely to be explored. Junior Rangers earn awards such as pins, certificates, and patches as they progress through the program. Programs are held rain or shine and it’s FREE! Each Junior Ranger must be signed up by a parent or guardian and can do so at the beginning of any program.

First day of the program is August 22, 2024.
