There are a couple of ways to The Long Drop. If you fancy a bit of a walk, park in Stonehaugh by the river (near the totem poles), cross the bridge back towards Stonehaugh and take the path signposted Stonehaugh Shields (next to the National Park sign) and follow it across open ground to a camp site. Exit the camp site in the SE corner near some farm buildings and follow the marked path from there. It continues through woods above the river and is clear most of the way. The walk back is the same way and will take around an hour in total. For those with less time park near Roses Bower farm (please don't go down the farm drive) and take the path across the fields.
Past the Long Drop (you'll see what drops when you get there) there is the remains of Holywell cottage just by the Black Pool. Holywell is named after a nearby sulphur well reputed to cure "ague, gravel and other obstructions". My own suggestion for such problems is a good curry and a few pints of strong lager.
