The Langness inquiry has heard how a previous owner of the land took steps to prevent rights of way being established.
Jamie Riggall said his family closed the area to the public for one day each year.
A footpath can only legally become a public right of way if there has been continuous, unrestricted access for 21 years.
Today is the third day of the inquiry and it will see John Welsh, another leading campaigner for the pressure group PRoWL, give evidence.
Yesterday, submissions from his colleague Ian Costain were described by advocates representing current land owners Jeremy and Frances Clarkson as 'largely anecdotal'.
The Clarksons legal representatives also said members of PRoWL had confused footpaths on the peninsula with tracks made by livestock.
The inquiry was ordered by Tynwald following a dispute which began when the Clarksons diverted a section of the path around their house, to protect their privacy.
It resumes at the Mount Murray at 9.30am today.
