Following the path under the main railway line past some impressive graffiti leads to what looks like the back gate to Dracula's Castle, keep going! Stick to the paths and do not cross the river!
This cache is a traditional plastic klipit type box for swappables, trackables and other tokens.
Please take care in this area as the water is unguarded and very few people will be seen at this end of the park and river.
If you end up at the waterfall you have taken the wrong path!
