Geocache Description:

Promenade Across The Causeway

A Multi-Cache in Porthaethwy (Menai Bridge) taking you across the causeway from Ynys Tysilio (Church Island) to the Menai Bridge via the Belgian Promenade.

The noticeboards at three of the stages give good information about the area, so I won’t repeat them here. GZ is only a short walk from the last stage. 

Visit the stages and identify which numbers replace the letters in the cache coordinate equation:


Stage 1 (Posted Coordinates) – Tysilio was from the Ath Century

Stage 2 – The date above the door = XBX

Stage 3 – The work was completed early in XXCD

Stage 4 – Year on the Carreg-yr-Halen slate = EXXX

Stage 5 – Just one of few footpaths in the world … it is FXX miles / XXXX km of fantastic views

Stage 6 – Pont y Borth (Telford’s Suspension Bridge) Finger Post ... the red number, there are 3, all the same... = GXX


You'll find the cache down at: N53 13.EAB W004 09.F(C+D)G

You'll need to walk under the bridge before finding the cache.
