Junior Rangers
Junior Rangers is one of California State Parks’ most popular programs. It is offered in over 70 state parks.
Junior Ranger activities cover a variety of topics, including animals, plants, history, weather, recycling and park careers. They are tailored to the local environment and the resources of the park where the program is held. Each activity provides a worthwhile experience that promotes further thought and action by the child, rather than just instruction.
The Junior Ranger program, in inspiring children to become resource stewards, is truly a promise to the future of California and the world.
Programs are catered to children ages 7-12.
