Limestone Canyon: The Sinks Professional Guide
Detailed Trail Description from our Guidebook
"Limestone Canyon is only open for scheduled events. At the time of this writing, the canyon has scheduled open-access days every other month.
Reservations are not required for open-access days, but with preregistration, you can join a variety of other docent-led activities including interpretive nature walks, bike rides of all levels, equestrian rides, and fast-paced “extreme cardio” hikes."
