Join us in beautiful Weir Canyon for this moderate paced cardio hike. Along the trail, you’ll pass through coastal sage scrub, grasslands, and oak woodlands where deer and bobcats are frequently observed.

Even though this is a slower cardio hike, it is faster than a walk. You must be able to hike 3+ miles per hour the entire time without stopping.
