Dangers & Annoyances
In mountainous areas you need to be prepared to deal with hostile conditions at any time of the year. The sudden appearance of low cloud and mist is common, even on days that start out clear and sunny. Check the weather forecast before setting out, and make sure you're well prepared with warm and waterproof clothing, sturdy footwear, food and drink, the appropriate scale map for the area and a compass (and the ability to use it!).
Even some walks described as easy may follow paths that go near very steep slopes and over loose scree. In icy conditions they can be extremely dangerous. In winter you'll need to take crampons, an ice axe, spare clothing, extra food and drink, and a torch, as it gets dark early.
The Met Office keeps the weather conditions constantly updated on its website (www.metoffice.gov.uk).
