Instructions
There is only a single stage. Find the cache at:
northfiftyonedegreestwentypointTPATGODTRBMBminutes
westtwodegreeseighteenpointTRBTPATGODTWWminutes
(The code above changed on 17/02/13)
Since some seekers may be making a special journey, confirmation of the coordinates is available here.
The cache is a micro and unfortunately has no room for trades, although it is large enough to hold small trackables.
The cache is intended to be approached in a manner in keeping with the theme of this puzzle, and that is how it was placed. I cannot comment whether it can be located and retrieved in any other way, but I would not wish you to attempt alternative approaches that might adversely affect the cache or its immediate surroundings.
En route to the cache I recommend trying to spot the feature at the waypoint given below as CURIO if you haven't seen it before; however, there is no clue to be found at this optional virtual stage.
Timings
Ahead of their visit, some seekers may be interested in typical timings. If I were to set out from near the posted coordinates, and travel by natural propulsion, I would park for at least four hours, possibly longer to appreciate fully the tranquility and to refresh myself en route as suggested below.
Photographs
So long as there are no spoiler photographs of the area around GZ, we'd be pleased to view your photos if you choose to log them, especially if there are any You've Been Framed moments.
Refreshments
It goes without saying that you should take along a picnic (although other facilities are available).
