Extreme Cardio Hike: Shoestring, Loma, to the Back Side of The Sinks

Join us for a strenuous, extremely challenging, fast-paced, early morning cardio hike in Limestone Canyon. Along the way we’ll be rewarded with panoramic views of Orange County and possible wildlife sightings. We will visit the back side of the Sinks to gain beautiful vistas of Agua Chinon and beyond. This over up to 13.5 mile cardio hike, completed in 3 hours, includes a 2000+ foot elevation change, and is for experienced, physically fit hikers who enjoy the challenge of multiple steep climbs and descents.

This activity will include one scheduled rest stop at the newly opened East Sinks Viewing Deck, offering a view of the “backside” of The Sinks. The approximately  13.5  mile cardio hike will average four (4) mile per hour fast-paced and is extremely difficult over steep terrain in the wilderness setting.

Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level-5 activity on the land.

Please bring a minimum of 100 oz. water and trail snacks.  Come prepared with a pack, sturdy closed toed hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail for the extreme fast-paced hike in a wilderness area. Each participant must carry his or her own pack and water.  Under-prepared participants may be denied access to this program.
