I would advise parking at Battens Drive car park to start this multi cache although it can get busy during good weather at weekends and holidays. The Visitor Centre is worth a trip if you've got time and if you have kids, there's a great playground to entertain them as well.
All but the final cache location can be found on tarmac paths suitable for wheelchairs, the final location is a little off the path so may require wellies if it's been raining.
If you are quick and accurate, this can be done in an hour, but I would leave a few hours to enjoy the scenery and the walk.
The co-ordinates quoted are for the first stage of the multi-cache.
Here you will find a lamppost with a number on it (ABCD)
Make your way to the 2nd stage located near a bridge and a junction of paths at:
N52 18.BB(B-C) W001 54.(A+B+C)D(B-C)
Here, you will find distances to a number of other locations (ignore the fractions of miles):
Studley - F
Stratford - GH
Bromsgrove - J
Birmingham - KJ
The third stage is at: N52 18.(K-G)G(J-K) W001 54.HFF
Here you will find a piece of artwork entitled "Flight over the Arrow Valley".
What year is on the artwork (LMNO)?
The 4th stage is a bench at:
N52 18.(L+N)(O+N)(N+M) W001 54.(L+N+O)(N+O)(L-N)
How many fishing spaces are there on the section of lake immediately in front of this bench (P)? You may struggle with this one as some have been replaced recently and they are not all in view... The answer needed here is 5
The final cache location is at:
N52 18.O(L+O)(P+O+N) W001 54.P(P-N)M
The cache is a small rectangular Tupperware box, Please make sure the cahe is well hidden when you have finished.
Enjoy the walk!
