From the OAC website, climbing at Lion's Head is "Tolerated as a non-conforming use of the park. Highly sensitive area. Strive for minimal impact and low profile. All fixed protection to be camouflaged. Do not disturb the cottagers. Approach via Bruce Trail entrance.
Good mix of sport and trad, starting at higher grades mostly 5.10 and above. Some routes have anchors. Some routes start from ground, others from hanging belay. Approach is from top; rap in. Extremely complex the first visit."
