From Carron Loop #9 - What's That Smell follow the direction of the purple National Looped Walk arrow along the minor road in the direction of Carron village. Turn left onto the green lane following the purple National Looped Walk directional arrow at N53 02.313 W9 04.171. The ground here can be very wet during the rainy season as it brings you towards the turlough (an area which floods annually in wintertime but disappears in summer).
At the start of the lane you will pass the last clue needed for the bonus cache. Cross the stile at the end of the lane to find the last cache. A short uphill trek takes you onto the main road within 100m of the parking.
After returning to your car at the end of the looped walk don't forget to calculate the co-ordinates for Carron Loop - Bonus. It's been a long walk so here's a hint - you can drive right up to the bonus cache :-)
We hope you enjoy the walk and are successful with all 12 caches :-)
