Welsh mountains are not high by world standards, but they should still be treated with respect. The fickle weather makes them more dangerous than you might expect, and you can easily find yourself disoriented in the low cloud and soaked by unexpected rain. If the weather looks like it’s closing in, get down fast. It is essential that you are properly equipped – even for what appears to be an easy expedition in apparently settled weather – with proper warm and waterproof layered clothing, supportive footwear, adequate maps, a compass and food. Always tell someone your route and expected time of return – and call when you get back so they know you’re safe.
