The institute’s code of practice, Outdoor UK Challenge Events, including the Three Peaks, says that organisers of three peaks challenge events ought to register all groups of 12 or more with the Glen Nevis Visitor Centre.
The institute and the Fundraising Standards Board asked landowners to inform the FRSB of any charities that were not complying with the code of practice when the new version of it was launched in March.
Jim Milligan, the manager of the Glen Nevis Visitor Centre, told Third Sector: "We did not particularly wish to name and shame the groups that have not adhered to the IoF code of conduct in its first year, but we will keep a closer monitoring eye on this in 2011 and report those who are ignoring the code to the IoF."
Under the Scottish Outdoor Access Code, event organisers must obtain permission from landowners before holding events in certain circumstances, such as when they might interfere with other people’s enjoyment.
A recent statement from the Highland Council said that a significant proportion of groups still failed to register with it.
Milligan said that since the introduction of the new version of the Institute’s code in March, more than 60 large groups had registered with it.
