Conejo Open Space Challenge
Here’s your chance to explore some of the best trails in the Conejo Open Space that many people are not familiar with! From March 1st through May 31st the Conejo Open Space Conservation Agency (COSCA) is challenging mountain bikers, hikers, trail runners and equestrians of all ages to try out some trails that may be new to them. See if you can complete all ten trails! If you do, you will be entered into a raffle and could win a prize donated by some awesome sponsors.
