Public transport
Snowdon is one of the few mountain areas in Wales with a dedicated bus network serving every trailhead. Arriving by public transport removes parking pressure, reduces costs on busy days, and supports sustainable mountain tourism.
Sherpa’r Wyddfa bus network
The Sherpa’r Wyddfa network is a purpose-built public bus service connecting all six Snowdon trailheads, Llanberis, Caernarfon, and Betws-y-Coed. Operated in collaboration with Eryri National Park Authority, it is designed specifically for mountain visitors. Timetables, fares, concessions, and ticket products can change with the season, so verify the current options at the official Sherpa and Traveline sources before travelling.

Rail access
Mainline rail — Bangor
Bangor on the North Wales Coast mainline (direct services from London Euston, approximately 3.5 hours via Chester) is the nearest mainline station to Snowdon, located approximately 11 miles from Llanberis. From Bangor, Sherpa S2 (high season) or local buses connect to Llanberis and Pen y Pass. Verify current services with Transport for Wales.
Conwy Valley line — Betws-y-Coed
The Conwy Valley line runs from Llandudno Junction (mainline interchange) through Betws-y-Coed. From Betws-y-Coed, the Sherpa S1 bus connects to Pen y Pass and Llanberis. This combination provides a scenic, car-free approach from the east.
Welsh Highland Railway — Rhyd Ddu and Snowdon Ranger
The Welsh Highland Railway (a heritage steam railway operating from Caernarfon to Porthmadog) has halts directly at Rhyd Ddu village and the Snowdon Ranger trailhead (Llyn Cwellyn). This makes it one of the most spectacular car-free approaches available — arriving by steam train to the trailhead is a genuinely memorable experience.
