Limestone Canyon is controlled and monitored by the Irvine Ranch Conservancy (IRC). All access to the land in this area requires permission from the IRC. Each month, there are a number of docent-led and open access days which the public can sign up for via their website.
There are many ways to ride around Limestone Canyon. This particular ride starts with a grunt of a fire road climb up to Loma Ridge, descends down to the “Sinks” and returns on a mild fire road path through an Oak Woodland area.
