I'm quite often put off from looking for caches with no obvious point of entry so I've tried to include as much detail as possible to help you on your way but if you prefer to just wander and get lost in your own thoughts then please feel free to ignore the next bit.
I've included a waypoint for what I feel is a suitable place to park on Wood Lea just off Kirk Brae and start the walk but there are plenty of other spots nearby, however please park considerately wherever you decide to stop.
Head up to the top of Wood Lea where you will find a path leading to the entrance into the college grounds. I've included the waypoint for this gate which is also the first cache site, next to the Kirkyard.
Once into the Police College grounds follow the road round to the right, past the Police Memorial on your right and Tulliallan Castle on your left and keep to the road until you see the entrance with the black gates, leading into the woods.
The public are allowed access into the grounds and it is popular with local dog walkers and also the local nursery and school. Take your time and enjoy your surroundings with Tulliallan Castle and the great trees that surround you.
Immediately as you pass through the gates into the woods, turn left off the main path and head up into the woods where you will find a dirt path leading to caches No.2, the Ice House and No.3, the Laundry House.
PS/GT 3 - The Laundry House
I'm afraid I can't really find much information on the Laundry House other than the fact that it was part of the Tulliallan Castle estate and did exactly what it said on the tin....the laundry. It is however still an impressive building (albeit ruined) in it's own right.
