Llanberis Path, Snowdon © Crown copyright. All rights reserved. 100022403, 2011 Distance: 9 miles (14½km) (there and back) Ascent: 3199 feet (975 metres) Time: About 6 hours (there and back) Grade: Mountain Walk Start / Finish: Far end of Victoria Terrace, Llanberis, off the A4086 (SH 581 594) Relevant Map: Ordnance Survey Explorer OL 17 (Snowdon & Conwy Valley) Parking There isn’t a car park at the start of the path but there are car parks in Llanberis village itself. In the high season you may descend by another of the Snowdon paths and catch the Sherpa bus back to your vehicle. © 2010 Snowdonia National Park Authority Llanberis Path, Snowdon Llanberis Path is the longest and most gradual of the six main paths to the summit of Snowdon, and offers fantastic views of Cwm Brwynog, Llanberis and over the Menai straights towards Anglesey. This is the most popular path amongst leisurely walkers as it is thought to be the easiest to walk in mild weather, but in winter, the highest slopes of the path can become very dangerous. The path mainly follows the Snowdon Mountain Railway track, and goes by Hebron, Halfway and Clogwyn stations. Before the railway was opened in 1896, visitors employed guides to lead them to the summit along this path on mule-back. A remarkable geological feature can be seen from the Llanberis path, the Clogwyn Du’r Arddu syncline. The syncline was formed over thousands of years, as the earth moved and transformed horizontal depos- its into vertical layers of rock. Safety Note The Llanberis Path and Snowdon Mountain Railway cross above Clogwyn Coch. -
Paragliding & Hang Gliding in Snowdonia
Paragliding & Hang Gliding in Snowdonia Introduction Hang gliding and paragliding are well developed adventure sports worldwide. Nowhere is this more evident than in Snowdonia, an area where many well known pilots have honed their skills. The complex geology and meteorology of the area make flying its world class sites both a pleasure and a challenge. Essentially paragliding and hang gliding are the simplest and lowest cost ways of flying free, hence the term 'free flight' used to describe both arms of the sport. With portable equipment, a pilot can take off from a hillside or be towed into the air. From there it is possible to soar and thermal like birds, travelling along ridges and circling up to the clouds to travel XC or 'cross country'. This is as close to being a bird as humans can presently achieve, open to the elements with no engine noise to destroy the peace. Hang gliding is the oldest arm of the sport and uses a rigid structure to maintain the wing's shape and integrity. The pilot 'hangs' prone beneath the frame generating very efficient flight. At present very little hang gliding takes place in Snowdonia because of a combination of the weight of the wing (about 30kg) and a lack of easy access to suitable take off points. Paragliding is the baby of the sport and is still rapidly developing, flying slower than hang gliders, paragliders are relatively quick and easy to master. A paraglider is essentially a twin skinned parachute which, when inflated during takeoff and flight, takes up a classic wing shape. -
Snowdon 500 – Route Descriptions
Snowdon 500 – Route Descriptions About Snowdon Snowdon is one of the most beautiful mountains in the world. Its grandeur impresses the visitor no matter which direction one looks at it. Its shape is like a starfish with six magnificent ridges radiating out, each with their own unique character and make up. The deep cwmoedd (glaciated valleys) dropping down from the ridges range from the easily accessible to those only reached by very experienced walkers and climbers. Snowdon, the highest mountain in England and Wales at 1085 m or 3560 ft, also offers a unique bio-diversity of rare flowers and insects, wonderful volcanic rock formations, fossils and disused mine works. For more information about the mountain and places to stay nearby visit www.snowdon.com Miners Track After registering and signing in at the start point in the car park in front of the Legacy – Royal Victoria Hotel you will be transported by our free shuttle bus to Pen Y Pass where you will receive your pre climb briefing before setting off for the summit of Mt Snowdon. The Miners Track to Llyn Glaslyn was built during the last century to serve the Britannia Copper Mines, abandoned in 1917. The Track is well defined and obvious until you reach Llyn Glaslyn but after that the path to the summit is considerably steeper and can be a serious undertaking especially in winter. The path starts at the far end of Pen Y Pass car park. At first the path contours gently with fine views down the Gwynant Valley on your left. -

The 610 Circular (Short and Long)
QMD Walks The 610 Circular (Short and Long) Copyright Bill Fear 2018 Relevant OS Maps include: OS Explorer OL17 (1:25), OS Landranger 115 (1:50), Harvey North Snowdonia Superwalker (1:25), Harvey Snowdonia North XT40 (1:40). Distance: Short 3-4 miles; Long 5 miles (Doesn’t include getting from and to car) Going: Demanding. Some rough ground. PRoW and FPs not always clear. Route finding necessary. Grade 1 scrambles on the Long. This route is ideal for either recceing the Welsh 3000s or a short or long day out from Llanberis Pass pass. There are a number of options to starting the long route and it can be varied by including/excluding the North Ridge of Crib Goch. Short Version 1. Start at the PRoW on the driveway up to Wern SH590591. Either follow the PRoW to just before where it joins the Llanberis Path SH584587 and then cross country to Derlwyn SH588586, CB OR cut up onto the ridge as soon as possible once you are in OA heading for Derlwyn. 2. From Derlwyn handrail the ridge line/fence to Tryfan SH597578. From Tryfan continue to 610m ring contour SH601574, 550m. There are a number of stiles along the way but the 610 stile is distinct in having rocks/boulders alongside the fence and as you cross the stile there is a flat place with a small ‘seating area’ (flat rocks below small earth wind stop) within 5m or so. Halfway Station is on the RHS as you approach and can be seen from Tryfan if you have visibility but can’t be seen from the 610. -

When we hear about the establishment of a new national park or nature reserve we conservationists breathe a sigh of relief and assume that the biological and cultural values of another area are now secured. Unfortunately, this is not necessarily true. Protected areas that appear in government statistics and on maps are not always put in place on the ground. Many of those that do exist face a disheartening array of threats, ranging from the immediate impacts of poaching or illegal logging to subtle effects of air pollution or climate change. -
Sites of Importance for Nature Conservation Wales Guidance (Pdf)
Wildlife Sites Guidance Wales A Guide to Develop Local Wildlife Systems in Wales Wildlife Sites Guidance Wales A Guide to Develop Local Wildlife Systems in Wales Foreword The Welsh Assembly Government’s Environment Strategy for Wales, published in May 2006, pays tribute to the intrinsic value of biodiversity – ‘the variety of life on earth’. The Strategy acknowledges the role biodiversity plays, not only in many natural processes, but also in the direct and indirect economic, social, aesthetic, cultural and spiritual benefits that we derive from it. The Strategy also acknowledges that pressures brought about by our own actions and by other factors, such as climate change, have resulted in damage to the biodiversity of Wales and calls for a halt to this loss and for the implementation of measures to bring about a recovery. Local Wildlife Sites provide essential support between and around our internationally and nationally designated nature sites and thus aid our efforts to build a more resilient network for nature in Wales. The Wildlife Sites Guidance derives from the shared knowledge and experience of people and organisations throughout Wales and beyond and provides a common point of reference for the most effective selection of Local Wildlife Sites. I am grateful to the Wales Biodiversity Partnership for developing the Wildlife Sites Guidance. The contribution and co-operation of organisations and individuals across Wales are vital to achieving our biodiversity targets. I hope that you will find the Wildlife Sites Guidance a useful tool in the battle against biodiversity loss and that you will ensure that it is used to its full potential in order to derive maximum benefit for the vitally important and valuable nature in Wales. -

Rock Trails Snowdonia
CHAPTER 6 Snowdon’s Ice Age The period between the end of the Caledonian mountain-building episode, about 400 million years ago, and the start of the Ice Ages, in much more recent times, has left little record in central Snowdonia of what happened during those intervening aeons. For some of that time central Snowdonia was above sea level. During those periods a lot of material would have been eroded away, millimetre by millimetre, year by year, for millions of years, reducing the Alpine or Himalayan-sized mountains of the Caledonides range to a few hardened stumps, the mountains we see today. There were further tectonic events elsewhere on the earth which affected Snowdonia, such as the collision of Africa and Europe, but with much less far-reaching consequences. We can assume that central Snowdonia was also almost certainly under sea level at other times. During these periods new sedimentary rocks would have been laid down. However, if this did happen, there is no evidence to show it that it did and any rocks that were laid down have been entirely eroded away. For example, many geologists believe that the whole of Britain must have been below sea level during the era known as the ‘Cretaceous’ (from 145 million until 60 million years ago). This was the period during which the chalk for- mations were laid down and which today crop out in much of southern and eastern Britain. The present theory assumes that chalk was laid down over the whole of Britain and that it has been entirely eroded away from all those areas where older rocks are exposed, including central Snowdonia.
