This cache can be found within the grounds of the Ross of Mull Historical Centre.
This is an interesting little museum next to an old mill, where you can browse the displays and archives, admire the mini wildflower meadow or take a break on the picnic bench by the stream. It's also the base for the ranger for the south of Mull, Iona and Staffa. The centre is usually open Monday-Friday 10am-4pm from Easter to October, entry by donation although free entry to the grounds. Please take care by the stream and do not climb on the walls of the mill ruins.
