Our accomplishments towards preserving and promoting Conejo Open Space

Our mission is to promote and maintain the open space and trails of the Conejo Valley, and to educate people as to their roles as custodians and protectors of the open spaces and the environment. Towards that end, we collect funds from generous like-minded folks and help recruit volunteers. We are proud of our accomplishments, some of which are listed here.

To help us continue to improve the Conejo open space areas for everyone to enjoy, please consider making a charitable donation or volunteering some of your time to help. We give a hearty Thank-You to those who contribute towards making the Conejo Valley open spaces such wonderful places to visit!
