I'm repeating this tip in a number of locations, because people simply do not seem to realise.
The mountains of Snowdonia are not high in comparison with others in the world. It's easy to underestimate their danger.
Welsh weather can change quickly. Slate and scree are slippery, even when it's not wet. It's easy to fall.
If you're walking, dress sensibly; take waterproofs, and good shoes (I've seen women trying to get up Snowdon in strappy sandals), and a warmer layer or two (temperatures are always lower the higer you go, and drop rapidly when it rains or clouds roll in). Use a good map, carry a whistle to attract attention (mobile reception is not guaranted), tell someone where you are going and when you expect to be back. Take something to eat and something to drink (drinking from streams is not recommended; there may be a dead sheep in the water a little further up).
Every year the volunteer mountain rescue people have to spend time searching for and rescuing people who are simply ignorant. Don't let it be you.
Compared to other mountain ranges in the world, Snowdonia isnt all that high, and as suc, it is often underestimated.
I know from personal experience that weather conditions on Snowdon can get very harsh indeed, and towards the top the ground often gets covered in Ice, especially between late Autumn and early Spring. The first time we tried to make the ascent we were forced to turn back only several hundred meters from the summit because the ground was just sheets of ice. Several other people were trying to make it accross, but we didnt see anyone make it all the way. On the way back down we saw a Mountain Rescue helicopter on its way to the summit.
It can also get extremely windy, with gale force winds not uncommon even only two thirds of the way up.
It would be a mistake to get up in the morning, see that it is sunny and pack light, because the weather up there can change for the worst very quickly.
Llanberis Mountain Rescue had over 100 call outs during 2008, which shows how much people under estimate the mountain.
Remember, you can never be too prepared.
There are lots of slate quarries throughout Snowdonia. The veins of slate were followed downwards; when the workings were abandoned the holes were left to fill with water.
A beautiful turquoise when the weather is good, they look so tempting on a rare hot day in Wales. But don't even think about it; the water is icy, and very deep, the sides are sheer or will rattle away as your hands try to grip.
Even qualified divers have died. So don't risk it, ever.
There are several ways to reach the summit, the easiest being the train. :-) They way we hiked was not an easy route, but what made it the most difficult was the last little bit up. It was very rocky and easy to lose your footing. So do be careful when climbing and wear sensible shoes.
No matter how nice the weather is when you start, make sure you're prepared for the worst. Snowdonia is on the coast and the weather can close in quickly and dramatically.
Some summits (e.g. Crib Goch) should not be attempted lightly whatever the weather and are best avoided when it is windy, even if it is a clear day.
If climbing in winter or in bad conditions please take the right equipment with you!each year there are many tourist who go up the snowdonia mountains who get caught in bad weather and sometimes do get injured!
Check the weather before hand,plan your route and let someone know of where you are going to climb! If you dont know the area well then it is easy to get lost when its poor visibility!
When you are driving in Wales you will be pleasantly surprised…the roads are generally in a good condition and well signposted. One thing that you do need to be alert for is sheep on the road!
One our day of driving through Snowdonia National Park, we spotted many sheep grazing on the side of the road, and willed them to stay put and not dash out in front of us as we passed by.
When we drove off the beaten track, along a one lane road, we turned a corner and suddenly these was a ewe and her lambs standing in the middle of the lane. Luckily we were only going slowly, so no problem. The sheep trotted ahead of us for a while before leaping up a grassy bank and disappearing into the bracken.
Just keep an eye out when you are driving and stick to the speed limit.
It is all too easy to take the mountain terrain lightly and to get into trouble by not following advice. Thankfully the mountain rescue helicopter is never too far away. In this case they were attracted by a flare set off by some Duke of Edinburgh Awards candidates who had somehow found themselves in difficulty in the middle of a field. It gives a city dweller like me a real sense of just how isolated this part of the country is. An ambulance just would not even have been able to access the field. It brought a lot of dangers to the front of our minds. Cars on the tiny country roads travel faster than they should and don't spare much thought for hikers. We found ourselves in the bushes more than once even though we were facing oncoming traffic and were clearly visible. If you go out walking, I would suggest taking a torch even if you plan to be home before dark. It's amazing how quickly darkness closes in amongst the trees!
even if its a sunny day in august with loads of people around, take a jumper, waterproofs, a first aid kit and HV clothing.
the cloud can move in incredibly fast and it would ruin the holiday somewhat if you walked off a cliff, broke a leg and died of hypethermia.
While driving in Snowdonia watch out for the wild goats which tend to roam the roads causing traffic tie-ups (that's because the cars stop and try to take pics!)
These ones were on the wall beside the road when we saw them, moving to a parking lot to fight and eventually across the road to the hillside.
