There are 3 methods of accessing the cache. (see additional waypoints for coordinates)
1. Entrance from Derby Road there is a public thoroughfare situated at the side of the secure car park which allows 24 hours access. Steps to the tunnel are situated behind car park space 70 and then down through the tunnel to GZ.
2. Steps from Upper College Street. This access does have lockable gates at the top and bottom of the steps, although I have never seen them locked.
3. Entrance from Tunnel Road in the Park Estate and head up through the tunnel. This access can be used by wheelchair users but be aware the slope is quite steep so you may require assistance.
I hope you enjoy this hidden gem and the history behind it. The Park Tunnel which leads most inauspiciously from the busy thoroughfare of Derby Road was originally built back in 1855, its purpose to facilitate access via horse-drawn carriage, into the Park Estate. The Estate has a history as a former hunting park for the Duke of Newcastle, the owner of nearby Nottingham Castle. In truth a mansion or palace rather than a castle, replacing the former structure which was burnt to the ground by unruly and unhappy local people. It’s said that the Duke of Newcastle originally ordered for the tunnel to be built with a specification of a gradient of no more than 1 in 14. The grand tunnel however, was constructed with a gradient of 1 in 12 , thus making it somewhat redundant from the inception of its life due to its unsuitability for horse-drawn carriages. These days, the Park Tunnel is used as pedestrian access to the Park Estate. The area became renowned as a popular part of the city for local wealthy luminaries to reside and to this day boasts many fine homes. The Park Estate is home to some wonderful Victorian architecture. It has the largest gas street lighting system in Europe which makes it rather atmospheric at night and the skyline is dominated by Nottingham Castle.
Logging Etiquette: Geocache hiders sometimes go through a great deal of planning to place their caches. As a result, they'd like to hear your feedback on whether you liked or disliked any aspect of the hide, or if you feel that some cache maintenance is required. Single word, acronym, or emoticon logs may be easier when you have a lot of caches to log, but it doesn't tell the hider or other finders anything about your adventure (or lack thereof) in finding the cache. Please keep this in mind when entering your log.
