I was recently on a stag do in wales which we used as a great excuse to head up Snowdon. The day began overcast and sadly stayed that way meaning by the time we got to the ridge of Crib Goch we were in the clouds.
Visibility stayed st this level for the rest of the route, luckily you could see enough to keep going and we were prepared for poor weather.
The route broke down after the first few miles leading to a slightly nervous hunt for anything resembling a path. Between five of us we were able to determine the safest route collectively suffering only a scraped knee and a few bruises.
We made it to the top, touched the peak and visited the highest cafe in the U.K. (3,560 ft high) after which we took the much kinder pyg track back down to the car.
If you enjoy a scramble and some incredible views I would highly recommend the Crib Goch route, just make sure you have some good ankle support, plasters and no fear of sheep.
