Hi Brian,
Late evening the place is pretty much deserted, the odd rambler and dog walker but not too bad, if you go far enough into the stand of pines then the road isn't really a problem.
This end of the woods isn't half as busy as the other end near Tockholes village itself. Unfortuantely for us, there aren't many large wooded areas this far south in Lancashire, up on the moors there are a few out of the way spots, but these are really only suitable for hammockers as the terrain is really undulating. It is easier for solo or pairs as you can be a little more discreet.
The area should suffice though.
Last night was the first night that I've not been up there this week.
Look forward to seeing you there.
