Exposures are fairly easily accessible, with some longer flat walks and some ascents. Walking will be fairly easy on paths, but shore sections and grassy hill slopes could be wet and slippery. Good boots essential; and warm clothes, waterproofs etc., as usual. The two full days will be quite long, departing 9am, return 6pm.  Packed lunches required on all days. We will probably need to rationalise car use on the Sat/Sun. Our leader will provide grid refs for each day in case people are travelling from different places, and will have notes and maps. Basically, though, the excursions are from the Aberdeen guide (Trewin, Kneller, Gillen, 1987) – now out of print but available online via the Aberdeen Geological Society. However, we hope to have copies of the relevant excursions.  

Accommodation will be in B & B and travel in shared cars.
