Rannoch Moor, a large expanse of around 50 square miles (130 km²) of boggy moorland to the west of Loch Rannoch, is partially in Perth and Kinross, northern Argyll and Bute, and Highland, Scotland. Rannoch Moor is designated a National Heritage site.
The area is the approximate location for the last great glacier in the United Kingdom at the end of the last ice age. As a result of this, the landscape is rising by around 3mm per year.
Flora and fauna
The B846 road links Pitlochry with Kinloch Rannoch and Rannoch Station.
The West Highland Railway has halts at Bridge of Orchy, Rannoch Station and Corrour. ScotRail  also run a direct sleeper service from London Euston. Bear in mind that Corrour is a request stop for the sleeper train and that passengers in the seated coach must change carriages at Edinburgh Waverley.
Good luck! The moor is a rugged wilderness, though there are routes. As well as the A82 road and the railway, a number of roads take you to the edges of the moor, with some paths crossing it. The West Highland Way skirts over the western section, from Bridge of Orchy to the top of Glencoe before heading off over the Devil's Staircase to Kinlochleven. A path from Kinlochleven to the Blackwater Dam then heads cross-country to reach Loch Ossian. From Loch Ossian walkers can follow a path to Loch Treig and then follow a trail known as the Lairig Leacach to Spean Bridge, or a rougher path to the head of Glen Nevis. There's also an estate track round Loch Ossian, though beware of deer fence gates which are sometimes padlocked, and from the eastern end another estate track heads via Strathossian House to eventually reach the A86 road near Loch Laggan.
Some walkers make use of the railway line. Maybe not the greatest of ideas but you can see the temptation to use something that's dry and straight when you're in the middle of a boggy moor, and when the trains seem infrequent. The section from Rannoch Station to Corrour has a couple of hazards to bear in mind - one fairly lengthy (and for the vertigo sufferers, high) viaduct, and Britain's only snow shed. This is an artificial tunnel where a cutting has had a roof added to protect the line from winter snows. Both these features make it difficult to see or avoid oncoming trains.
Hikers may enjoy tackling Beinn Na Lapp (a Munro) or the smaller Leum Ulleim (William's Peak), both starting from Corrour Halt. For Beinn Na Lapp head toward the Youth Hostel then pick up the track for Loch Treig, then head uphill over the heather. For Leum Ulleim there's a path running northwest from the station to begin with.
Very little! There is no shop at Corrour, nor at Rannoch Station. The nearest shops are in Kinloch Rannoch, Fort William and Tyndrum.
Eat & Drink
It's an upland wilderness area, so be prepared for weather and possibly midges.
When you're ready to return to civilisation (and before too long, you will be!), head south to Tyndrum, Crianlarich, Loch Lomond and Glasgow, east for Stirling and Perth, north to Fort William or west to Oban and the Hebrides.
