The aim of the weekend is to explore some of the rugged terrain between Loch Ailort and Loch Morar in hectad NM78. The exact itinerary will depend on the weather but should include the 600 m Sithean Mor (NM7286, the enigmatic second site for Diapensia lapponica (Diapensia)) and surrounding hills, coires and lochans, and possibly also the Ardnish peninsula. Calcareous flushes with species such as Saxifraga aizoides (Yellow Saxifrage), Pinguicula lusitanica (Pale Butterwort) and Platanthera bifolia (Lesser Butterfly-orchid) are known to occur, along with a range of western ferns and wintergreens, but much of the ground is unexplored. Hill-fitness is required. Accommodation (potentially from Friday 3 June to Monday 6 June) nearby is limited so early booking is advisable.
