OS sheet 56 shows a handy way up. Follow the Wicklow Way in about a kilometre from the carpark, to where there is a distinct bend. Here the WW meets a track running due north from the slopes of Ballinafunshoge. There is now a sturdy new fence running along this path uphill to the top of Sleamaine. All you have to do is follow this old track up, avoiding any tree-hugging. You will need to cross this fence once, which isn't easy as it's shiny and new, but here and there there are angled struts of wood at certain places in the fence. These can be used as aids to gain height for lifting your arthritic legs over the barbs. The OS map is so accurate it even shows this track shimmying around the top, illustrating exactly where the high point is. Linkback: https://mountainviews.ie/summit/690/comment/20520/
