The route

The Llanberis Path starts at Victoria Row in Llanberis and climbs steadily to the summit of Yr Wyddfa and shares ground with the Snowdon Mountain Railway, which the park warns walkers to keep off. The park authority grades it hard and strenuous, with 975 m of ascent, and says most of the 600,000 summit visitors a year use it. The map line runs one way, from the village to the summit.

Before you go

Safety and access notes come from official pages. Conditions change, so read the linked page for the day you walk.

Getting there

Nearest station or stop to the start in our dataLlanberis (SMR) (rail, Snowdon Mountain Railway), about 0.3 km in a straight line.
The Sherpa'r Wyddfa bus calls at Llanberis Interchange. The page asks walkers to use Llanberis car parks, not narrow residential streets. Check the Sherpa site for services. Source (opens in new tab)

Step-free and pushchair access

The official page does not say whether this route is step-free or suitable for pushchairs, so we do not either. Check the official page (opens in new tab) or ask the site.

Safety

The page calls walking along the Snowdon Mountain Railway track extremely dangerous and asks walkers to keep clear of the rails and stay on the path. Eryri National Park Authority: Llwybr Llanberis (Welsh page) (opens in new tab)
The page says steep hills, rough ground and some scrambling are possible, that full mountain walking gear and navigation skills are essential, and that the mountain should not be climbed on a whim. Eryri National Park Authority: Llwybr Llanberis (Welsh page) (opens in new tab)
The authority advises checking the Met Office forecast a few hours before you set out, not relying on it alone, and being ready to turn back. For a mountain emergency call 999 and ask for the police, who bring in mountain rescue. Eryri National Park Authority: Safety advice (Welsh page) (opens in new tab)

Seasonal access

The page says specialist equipment may be needed in winter conditions, and directs walkers to the Yr Wyddfa Fyw site for current weather and ground conditions. Eryri National Park Authority: Llwybr Llanberis (Welsh page) (opens in new tab)
