A slow-paced beginner mountain bike ride for adults in Limestone Canyon, part of OCParks’ Irvine Ranch Open Space, through sycamores, oaks, and habitat native to California. The route takes us to The Sinks, Orange County’s own mini “Grand Canyon.” Along the way, we will stop and talk about the local habitat, and hope to see some of our local native animals and raptors.

This ride is for adult riders only. Allow up to 2.5 hours of riding time.
