Head down isn’t private land, you can ride there whenever it’s forestry commission. As long as you know where to look it’s pretty easy to find the tracks. They usually just mix it up before the race cutting in new bits and adding them to the existing trails. Most of the trails finish at the train tracks which run near the A3
I found a non-waymarked trail near the blue on a night ride recently. It was just about within my skill level, until the drop-offs got quite big (: Need to revisit in daylight.
