Sugarloaf Hill is usually climbed from Bay Lough Car Park, S03056 09981 B, ample parking there. Cross the road and follow the wall and the eroded path all the way up, it's steep enough but you'll reach the top in 40-45 mins (or 30 mins at a brisk pace). Keep the wall to your left and once you reach the top you can go right/south-east and commit to a longer walk to Knockmoylan and Knockmealdown. The stone wall also continues on to Knockmealdown and on a clear day you can enjoy some great views of Knockmealdown if you approach it from Sugarloaf.

The summit is marked by a cairn, there is now a 2019 diary where you can log your visit. You can just about see the white plastic bag with the diary under one of the stones in the picture.

Care is needed on the way down since there are a lot of loose stones and it can be slippy after a wet spell but you would have noticed this on your way up. You can move to either side of the path where the ground is grassy but it can also be muddy.

Alternatively, you can park at the second lay-by after the hairpin bend (if coming from Clogheen), S04058 11836 C, cross the road and follow the faint path past Grubb's monument. It should take you about an hour to reach the summit. Linkback: https://mountainviews.ie/summit/170/comment/20344/
