Fairly easy, level walk round a Reservoir. The Visitor Centre, which has a good sized Car Park, Information Boards, Toilets (Summer only) and sometimes an Ice-Cream van, can be found at N50* 31.743 W4* 35.522. From there, simply follow the Reservoir round, until you find the Cache, which is an lunchbox hidden in the side of an old farm track which would have run through the fields before they were flooded for the reservoir.
