When the Mission Road was developed a new jaunting car entrance into the Park was provided nearer to the jaunting car stand located at the Kings Bridge entrance
The location of this new entrance is just beyond the end of the Cherry Tree Drive at Killarney House and was chosen carefully in order to preserve the integrity of the landscape adjacent to Killarney House and to avoid interference with plant collections and tree collections in that area.
I do not consider that the new entrance suggested in the question would be in keeping with the plans for the redevelopment of Killarney House and Gardens for which the local authority has indicated a decision to grant planning permission.
