A pleasant stroll, taking you past some of Ely's many drinking establishments. Please note there's no need to actually enter any of the pubs to solve the clues though!
At each location, you'll need to find a number and note the letter it relates to, so you can get the location of the final cache. The final is a small "natural" container, with enclosed log. Please bring a pen or pencil
Once you have all the values, the final can be found here:
N 52 E(B-A).(C/2)31
E 000 FD.121
There's a lot of free parking in Ely, the most convenient for starting this cache is located on Barton Road at N52.396460 E0.258542
The terrain listing reflects the steep hill you may need to navigate, even though Ely is in the fens! Look out for muggles at the final location, and please replace carefully. The route takes you close to another pair of caches:
GC1B4TX - Take a seat
GC4GNPC - Ely riverside
