Canyoning tours, courses and river rescue training are adventure activities that contain a number of known and unknown hazards and risks, and that an unpredictable or uncontrollable natural event may occur that could possibly cause those on the activity serious harm or death. It is important that all participants undertake the activities willingly and understand there could be consequences should they ignore the directions of Big Rock Adventures Ltd guides and instructors or fail to disclose medical or physical conditions that may affect themselves or other participants. It is always OK to say “no” and we have a fun focused, “challenge by choice” philosophy.

Big Rock Adventures Ltd will take all reasonable and practicable steps to keep those involved in these activities safe, e.g., professional and qualified instructors as well as top-quality equipment while operating under an audited safety management system that carries the ‘AdventureMark’ brand.

Before joining any activities, Big Rock Adventures Ltd requires all participants to sign an acceptance of risk form as an acknowledgment they have read and understood what the known risks within the activities are, as well as a declaration that they are free of any impairment (drugs, medications, alcohol) and are physically fit and capable to join.  Big Rock Adventures Ltd is unable to guarantee participants safety and signing the risk acknowledgement and fitness declaration form does not waive our commercial obligations under the HSWA Adventure Activities Regulations 2017.



Canyoning and river rescue and raft guide training requires a reasonable level of physical fitness and agility.

You must inform us of medical conditions, injuries and fears before the trip.


Canyoning and swift water training are available at Covid 19 Alert Levels 2 & 1.  It is a requirement that all participants are free of any cold and flu symptoms.  Big Rock Adventures staff reserve the right to turn away anyone that in our opinion may cause a risk to us or others during your adventure.
