Nice short route
Distance 6.1 km
1. Llanberis Lake Railway station (SH 58210 59879)
The walk begins outside the Llanberis Lake Railway station and not at the popular Snowdonia
Mountain Railway which is a little further along the A4086 towards the town centre.
There is plenty of parking in and around the town near the Snowdon Mountain Railway and opposite
To begin the walk, follow the signs for Dolbadarn Castle and the National Slate Museum and
opposite a car park turn right. Cross a large slate footbridge over the River Hwch and follow a
winding track up through the woods to the castle.
2. Dolbadarn Castle (SH 58600 59792)
The castle overlooking Llyn Peris was built by the Welsh prince Llewellyn the Great during the early
13th century, to protect and control the Llanberis Pass - a strategic location, protecting trade and
military routes into north and south Wales. Entry to the castle is free and it’s worth exploring.
The castle comprises a courtyard, surrounded by a number of towers and a round keep, said to
mimic the Norman castle found at Pembroke.
Edward I and his army took the castle in 1284 and it gradually fell into disrepair. The ruins were
popular in the 18th and 19th century with artists and were famously painted by Turner in 1802.
Retrace your steps back down and over the footbridge to the road. Turn right along the road
towards the National Slate Museum and First Hydro-Electric power station.
Crossing between the lakes, you’ll get your first glimpse of the views to come, with the mountains
and Llanberis Pass looming in the distance.
Turn left at the mini-roundabout and walk towards the National Slate Museum.
3. The National Slate Museum (SH 58563 60186)
Dinorwig Quarry closed in 1969 but the Victorian workshops, with the largest working waterwheel in
Britain were preserved.
The Industrial Revolution in the 19th century led to an explosion of towns and cities across the country
and saw demand for slate take off as a roofing material. It was also exported across the developing
In 1882 the county’s quarries produced over 280,000 tons of finished roofing slates and in 1898 the
slate trade in Wales reached its peak with 17,000 men producing 485,000 tons of slate.
4. Vivian Quarry (SH 58661 60500)
From the museum, walk across the railway track and through the railway barrier-gate towards the
old Vivian Quarry.
Pass through a large stone archway emerging inside the old quarry hole littered with old quarry
When production stopped in 1958, the lower half of the quarry gradually flooded to form a deep,
blue lake - up to 18m in places and now popular with scuba divers.
Follow a winding track to the lakeside viewing platform for a closer look.
These days rock climbers also come here to climb in the old quarry, and you can see some traces of
the climbing routes dotted around the sheer rock faces.
Walk back to the front of the museum and walk over to the far side of the car park - passing a café,
toilets and gift shop (SH 58461 60462).
Follow a path of slate chippings towards the lake and along a winding track up to a grassy view
point below the old quarry hospital (SH 58295 60604).
There are spectacular views here over the lake and you’ll regularly hear and see the old steam train
carrying passengers on a scenic trip beside the lake.
Walk up the wooden steps towards the hospital and marvel at the fascinating old photographs and
medical equipment inside.
5. Quarry Hospital (SH 58317 60703)
The hospital here was for the men who worked at the Dinorwig Quarry in the 19th and 20th centuries.
The idea was to have a hospital on site so men could get back to work as soon as possible after
The hospital treated a range of injuries, from broken bones to lost fingers and crush injuries, and
employed the latest medical techniques of the time.
The hospital was even equipped with an x-ray machine, just three years after its invention in
Germany, and was one of the first buildings in the area to have both hot and cold running water
Turn left out of the hospital and follow a road through the entrance gates. Turn left up a rough track
of slate chippings signposted as the green route, and head up a winding track into the ancient
