Start at the virtual waypoint coordinates by Clifton Down shopping centre, not far from the end of Cotham Hill. Originally, there was a taxi rank sign here: a blue sign saying "Stand for 3 Taxis" with a time range underneath it in the format: AB am - C:DE pm
Since the cache was placed, this sign has been moved. Use your cunning and ingenuity to find a similar sign nearby - there are plenty of tips in the logs such as "look further down the road". You might even be able to use Google Maps Streetview or similar to find the coordinates
The final cache is located at: N51 27.9(A+A)6, W002 36.38C
From here, the best route is to the cache is to go up the lovely Cotham Hill, full of cafes and shops. Please be careful of muggles when collecting final cache...
