I'm all for making the hills and mountains as person and user friendly as possible but this one confounds me. While the Hellfire has it's history and some great views to hand it certainly is no Glendalough. The forestry isn't pleasing to the eye and it's walking routes are limited, and that's before we consider the poor accessibility or indeed the eyesore that it creates.
Quite how the powers that be feel that it warrants this level of investment isn't clear to me, unless I'm missing something here.
