Excellent walking area for all grades from a casual stroll to serious hiking.
The views from the top of the Rock are amazing.
The entire South East from above the Arklow sandbank Windmills, across all of county Wexford and it's coastline, right on to the Commeragh Mountains.
If it's a high cloud day with no haze on the horizon, you can see the mountains in both North and South Wales.
Well worth a visit and all free. Lots of history also.
