I think ive only been lost two or three times over the many years ive been walking, the last time, was quite a few years ago.
I fully research the walk and terrain i intend taking, how far it is, roughly how long it will take, and possible escape routes in inclement weather.
The last time i got lost, was approaching Carnedd Lewellyn some years ago.
A beautiful day suddenly went downhill quickly, with heavy mist and rain that had not been forecast, suddenly appearing from nowhere, it was so fast that returning back to Cwm Eigiau was a challenge in itself.
I knew roughly where i was in the Carneddau, but navigating was just about impossible, and i located certain sheer drops into emptiness somewhere in the Yr Elen direction, that i kept going round in circles for well over an hour.
In fine weather you can navigate and avoid the dangers high mountains sometimes provide, but when your going round in circles, you can often venture onto difficult terrain without realising it.
The weather was so bad, i had to make an ascent into the Ogwen valley, and phone a friend to collect me, and take me back to Cwm Eigiau.
The famous Carneddau mist was especially thick that day.
I much prefer to walk in good weather, not so much because i hate the rain and mist, but if a walk is a good one, its worth seeing the stunning views.
Getting lost thankfully is a rarity, i know my intend routes, and if the weather is that poor, i arrange another day.
