| This cache may be completed in conjunction with "Canal de Nante à Brest - rigole d’Hilvern "(GCTJPQ) |
To find this cache by the suggested route will take you on a walk of about 1.5km along the tow-path of the Nantes-Brest Canal. Apart from the last 30m, the path is crushed stone so is suitable for wheelchairs, prams, bicycles etc.
This stretch of the canal is part of the ‘Hilvern Ladder’, a flight of locks which raise the canal from the river L’Oust at St. Sampson, up to the ‘bief de partage d’Hilvern’ which is one of the three man-made sections of the canal. This joins the canal to the river Blavet at Pontivy. The locks on this section are so close that there has to be holding ponds for the water used to fill the locks. These ponds, on each section of canal between the locks, teem with both flora and fauna. As you walk along, watch carefully for the blue flash of the wings of a kingfisher, flying just ahead of you. In summer, amongst the lily pads, you may catch sight of large pike perch, roach etc. or see a grey heron or white egret fishing for smaller fish. If you do spot any unusual wildlife, please include a short account in your log.
Suggested parking is at N48° 06.831, W002° 49.932. From here, cross the road bridge to the tow-path. At the given waypoint is the first of 3 lock-keeper’s cottages that you will need to find to work out the final position of the cache. Above the main door of the cottage is the number and name of the lock. The 2 digit number is AB
Substitute the digits in the next waypoint which is:-
N48° 0B.A[B-4][A-2] W002° 4[A+2].[A-2][A-2][A+2]
This will take you to another Lock-keeper’s Cottage, the number above the door is CD. Using these digits with those from the first cottage, proceed to the next way-point which is:-
N48° 0B.[C-D]BB W002° 4[C+1].[A+1][C-A][D+1]
This brings you to the third cottage, again use the digits EF to substitute in the final waypoint to find the position of the cache:-
Cache Position :- N48° [C-F]B.[C-D]D[D+E] W002° [C-D][F+1].[A+1]B[C-A]
To reach the cache you will need to cross the canal and take a small track on the right. Please make sure that the cache is well hidden when you leave it, as the area is frequently used by huntsmen and fishermen. In summer the tree cover may hinder the accuracy of GPSrs so I have included some spoiler photographs.

Multicache tres sympatique qui donne envie de faire tout le canal a vélo.
Nous avons sorti le GPS et les poussettes pour cette journée ensoleillée et d'initiation a nos geocacheurs en herbe.

Au cours de notre tour à vélo de Croisic à Châteaulin en passant par Nantes, puis suivant le Canal de Nantes à Brest, nous avons découvert cette jolie cache. Un grand merci! La Bretagne est merveilleuse.
