CANCELLED due to Trail Conditions: St Patty’s Day Evening Cardio Hike: Fremont Canyon Coal Mine

Come enjoy a scenic evening cardio hike in the remote Fremont Canyon Nature Preserve, part of OCParks’ Irvine Ranch Open Space. Our hike climbs steeply from the mouth of Fremont Canyon, past an abandoned coal mine, up to the Fremont Weather Station. After enjoying the view, we’ll turnaround and hike back the same way to our starting point.

This challenging hike involves steep climbs and a 1200’ elevation gain but the rewards are sweeping views of Fremont at sunset. Please arrive 15 minutes early and come prepared with a sturdy pack, water, closed-toe hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail.

Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level-4 activity on the land. Please visit our FAQ page for answers to activity specific questions you may have prior to registering.

Each participant must carry his or her own day pack and water and be comfortable hiking an average moving pace of 3+ miles per hour. Please make sure you have a minimum of 70oz. (2 quarts) of water. Under prepared participants may be denied access to this program.

Please note that you will be asked to adhere to the following measures in order to participate:

  • Be registered in advance, no walk-up registration is permitted.
  • Arrive with all necessary equipment to keep you safe on the trail, including water, proper attire, and closed-toe footwear, first aid, health needs etc.

  • All participants are required to sign a liability waiver upon arrival at the staging area and before beginning the activity. The waiver can be previewed here: IRC Liability Waiver
