"The guide itself is aimed at those beginning to explore bouldering outdoors to
those established in the mid-range grades.
Climbing is fantastic exercise but comes with its own risk of danger and injury.
Transitioning from indoor to outdoor climbing can be difficult and the risks are
greater outside due to more variables. Please seek guidance as needed either
from your local climbing wall or at the nearby Tollymore National Outdoor
Centre where a number of introductory courses are run regularly."
