Wow, Cave Dale is a tough one as the rocks are big and chunky, they move everywhere, they are limestone and slick in the wet, its steep in sections and its often rammed with walkers. But you can find your level. Broken into three sections the top part is the steepest roughest and narrowest. The middle part is more easily rideable but is still tough. You then go through a very narrow pinch point before it magically opens out to reveal a really wide green valley with a rocky strip in the centre. You can ride up the sides a little for a smoother ride and avoid any walkers. There are a couple of opportunities for jumps as you head towards the bottom, great fun. At the end it pinches you in agan on looser stones and so you need to be aware of this.....stop for the gate! Through here and as if exiting a magical kingdom you are ejected into the centre of Castleton. Pure magic. (unless you went in a bit ambitious at the top, in which case you might have an even more magical view of the valley.....from an air ambulance)
