This was probably the only hill that I just got "near the top" as the terrain and trees conspired against me.
From the parking area head up the forest track all the way to the foot of Inner Hill. I walked the whole track around Inner Hill, but I couldn't really see any way in to the top. On the map there was a little fire track, but the trees were still really dense and it would have been a grim job to travserse that especially in the snow too.
I'm happy for anyone to tick Inner Hill off from the main forest track, but if you do find a better way up, please let us know. Maybe save this one for the more clement weather.
Follow the route above or find it on OS Maps.
You may as well continue on and bag Dryhope Hill which is just around the corner.
