[RWD version 1 ] This is a pleasant short walk in a forest around Downs Hill. One congenial place to start and finish from is the Grove Bar which is at the south end of Old Downs Road. This road will give you access to the forest, though first there is an approximate 2k road walk.
The critical thing is that you leave the road at O 25996 10581 going through what appears to be a very unpromising small path. It is easy to miss.
Having done that you quickly find yourself on a substantial forest road which you will follow for most of the track. You can go around this route clockwise or anticlockwise. We chose clockwise and went left which is SE initially.
What was surprising about Downs Hill is that where the trees allow there are excellent views towards all cardinal points of the compass. Early on there are views to the east and coast including the view towards Wicklow town.

Later on there are views to the SW over much of Central Wicklow. This moody picture includes Scarr, Tonelagee and even has Turlogh Hill and is reached from a short spur off the main forest road at the western extremity of the route. There is a magnificent stand of substantial Sitka Spruce.
Later we found this evening spread towards the NE including from the left the triple topped Little Sugar Loaf, the double topped Bray Head Hill and the telecom tower topped Kindlestown. Towards the left you can see a white horizontal bar. This is Sorrento Terrace, an extraordinarily recognisable place from much of NW Wicklow.
One curiousity we found looking towards Bray Head Hill was beside the small white painted trig pillar was a larger pillar to the right. It was the Kish Lighthouse.
Return the way you came along the Old Downs Road and perhaps have a drink at the Grove Bar.
There is another route on MV around this area in track/4058 which starts from a different place.
