Start early from Llanberis and climb Snowdon via the Llanberis Path, the gentlest of the classic trails. A 6-7 hour round trip to the summit of Wales' highest peak, with 360° views of the Irish Sea, Anglesey and the surrounding mountains.

Must-Try Foods in Snowdonia

Cawl (Welsh Stew)

Wales' national dish — lamb and root vegetables (turnips, carrots, potatoes) slow-simmered for hours into a hearty broth, served with fresh oat bread. Perfect for warming up on a chilly mountain evening. The version at the Royal Goat Hotel is widely regarded as the best in Snowdonia.

Welsh Rarebit

Rich melted Cheddar cheese blended with malt beer and Dijon mustard, poured sizzling over toasted bread. Pete's Eats in Llanberis and the Royal Oak in Betws-y-Coed are top choices for this classic dish.

Purple Moose Craft Ale

Craft beer from the local Porthmadog brewery Purple Moose, brewed using Snowdonia mountain spring water. Their flagship "Snowdonia Ale" has an amber body with nutty aromas — the perfect reward after a day's hiking.

Portmeirion Afternoon Tea

Enjoy a classic three-tier English afternoon tea at Caffi Glas or Hotel Portmeirion — scones with clotted cream, finger sandwiches and delicate pastries, accompanied by the sparkling waters of the estuary, as if transported to the Mediterranean.
