Moray runs from the fertile coastal plain of the Laich along the Moray Firth up into the foothills of the Cairngorms in the south, threaded the whole way by the River Spey. Sandy bays, river haughs and farmland give way to rolling heather moor and forested hill ground as you move inland. Speyside is classic Scots pine country, with remnants and plantations of native Caledonian pinewood alongside birch, oak and mixed conifer forestry. Mushrooms turn up under the pines on mossy, blaeberry ground, in birchwoods, and along the wooded riverbanks and old estate policies.
Sheltered by the hills to the west, Moray sits in a rain shadow and is one of the drier, sunnier corners of the Scottish Highlands. Summers are mild and autumns relatively settled, though damp spells off the Firth still give fungi the moisture they need. It is excellent ground for boletes and chanterelles in the pinewoods and birch, with the Speyside conifer forests especially reliable in a good autumn. Much of the land is estate or farmland, so stick to access rights, the Scottish Outdoor Access Code, and tread lightly.
