Snowdonia Trail & Visitor Guide
Snowdonia · United Kingdom · Approximately 2,176 square kilometers (840 square miles), covering northwest Wales in Gwynedd and Conwy counties.
Why Visit Snowdonia
Snowdonia (Eryri in Welsh) covers 823 square miles of northwestern Wales, centered on Snowdon (Yr Wyddfa) at 3,560 feet — the highest mountain in England and Wales. The park contains 90 mountain peaks, 23 lakes, and some of the most dramatic ridge walks in Britain. The Snowdon Horseshoe is widely considered the finest mountain walk in Wales, traversing knife-edge ridges around a glacial cwm.

Wildlife You May See
Entrance Fee
No entrance fee to the park. Car parks charge fees: Pen-y-Pass car park costs about £40 for a full day and must be booked in advance online during peak season. The Snowdon Mountain Railway costs roughly £49 return to Summit station.
Getting There
Nearest mainline rail station is Bangor on the North Wales Coast line; Betws-y-Coed is on the Conwy Valley branch line. The Sherpa'r Wyddfa (S-series) bus network connects Llanberis, Pen-y-Pass, Beddgelert and Betws-y-Coed; use it to avoid full car parks. By car, the A5 and A4086 reach the main Snowdon trailheads; from Manchester or Liverpool it is roughly a 2-2.5 hour drive. Pen-y-Pass parking must be pre-booked.
Where to Stay
Llanberis is the main hiking base with hostels, B&Bs and the YHA Snowdon Llanberis. Betws-y-Coed has hotels, guesthouses and is the largest tourist village. Beddgelert offers quieter accommodation near the southern trails. Pen-y-Pass YHA sits at the Snowdon trailhead. Campsites include Llyn Gwynant and several around Capel Curig. Book well ahead for summer weekends.
Best Time
May to September offers the longest daylight and most stable weather, but July-August brings crowds and full car parks; arrive before 8 am or use the Sherpa bus. Winter (November-March) requires ice axe, crampons and winter skills on the high routes.
Safety
The top hazard is rapid weather change: summits can drop below freezing with cloud, high wind and zero visibility even on mild valley days. Check the Met Office mountain forecast before setting out, carry map, compass, waterproofs and extra layers, and do not attempt Crib Goch in wind or wet conditions. Mountain rescue teams are called out hundreds of times a year, frequently for ill-equipped walkers and benighted parties.
