Limestone Canyon Hike to Both Sinks ***Must Register on

I’m excited to do another hike to the Sinks! This is an event through the Irvine Ranch Conservancy, so you must register at the below link as well.

The hike will be 10 miles with 1,000 ft. of elevation gain.

Join us on this fast-paced hike over the ridge and the through beautiful Limestone Canyon Nature Preserve, part of OC Parks’ Irvine Ranch Open Space. While this will not be a cardio hike, it will be a steady pace of 3 mph with short breaks at the East and West Sinks viewing platforms. We will enjoy a view of wonderful vistas in addition to spectacular view of The Sinks. This hike involves hiking on both double and single-track trails with an elevation gain of 1000.

Please come prepared with a sturdy day pack, water, snacks, closed-toe hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail on this half-day hike in the wilderness area. Under-prepared hikers may be denied access to the event.
