This circular lakeside walk comes with no nasty ascents. Llyn Ogwen sits peacefully beneath Snowdonia’s towering peaks, with dramatic views up towards the mighty summits of Tryfan and Glyderau. Legend has it that King Arthur’s sword, Excalibur, rests in the waters here, adding a mystical air to this enchanting setting. Park at Tryfan car park and begin the trail at Ogwen Cottage, joining the path that skirts the perimeter of the lake. The terrain is relatively flat, though it can get boggy at times.

Medium walks in Snowdonia/Eryri (3-7 miles)

Mawddach Estuary in Barmouth

Barmouth Panorama walk

Snowdonia is just as breathtaking at sea level as it is from the mountain tops. Located on Snowdonia’s west coast, Barmouth is a sweet Victorian seaside town lying at the mouth of the Mawddach Estuary. To begin this scenic walk, climb up from the car park just outside of town and you’ll see the coast in all its glory; unfolding before you are far-reaching views over the estuary, Cardigan Bay and the Cader Idris range. Allow time to stroll around the pleasant Victorian Gardens en route, and pop down into Barmouth afterwards for lunch or afternoon tea. Note that some sections of the walk are steep and can get very wet and boggy.

Distance: 4 miles

Difficulty: Moderate

Stay nearby: The Moorings Barmouth | Sleeps 4 + 1 dog


Aber Falls

Aber Falls walk

This circular loop to one of Wales’ best waterfalls is a favourite Snowdonia walk. It rambles through leafy Coedydd Aber Nature Reserve and follows the Afon Rhaeadr-Fawr river past the ruins of an Iron Age roundhouse and kiln to the majestic, 120-foot spectacle that is Aber Falls. Come in winter when the falls are fully engorged and at their most magnificent. On your return along the North Wales Path, look out for swooping buzzards and peregrines, as well as Carneddau ponies – semi-wild horses native to the area. The local village of Yr Hen Felin has a couple of cafes if you’re peckish afterwards.

Distance: 4 miles

Difficulty: Moderate

Stay nearby: Werdnas Cottage | Sleeps 4 + 2


The Lonely Tree at Llyn Padarn

Llyn Padarn Walk

This lakeside walk is one of the best walks around Snowdonia. It loops around Llyn Padarn and rewards wayfarers with dramatic views of Yr Wyddfa's/Mount Snowdon’s lofty peak. The wooded lakeside path weaves past a pretty waterfall, a 13th-century castle, and a famous tree nicknamed ‘The Lonely Tree’, whose stark appearance is mirrored in the seductive stillness of the lake’s waters, creating an atmospheric scene that has captured the attention of photographers far and wide. Veer off for snacks in the village of Llanberis.

Distance: 5.1 miles

Difficulty: Moderate

Stay nearby: Hen Gapel | Sleeps 4 + 2


Path at the top of Mount Snowdon

The Snowdon Horseshoe

One of the most spectacular Snowdonia hiking trails, but also one of the hardest, this heart-pumping route is only for experienced hikers - and those with a head for heights. Starting from Pen y Pass car park, it follows the jagged ridgeline of three mighty peaks: Crib Goch, Crib y Ddysgl and Snowdon/Yr Wyddfa – the latter two being the tallest mountains in Wales. Avoid the route in bad weather as high winds can be dangerous, but go on a clear day and you’ll be rewarded with the most phenomenal panoramas - just don’t look down!

Distance: 6.8 miles

Difficulty: Challenging

Stay nearby: Bryn Llinos | Sleeps 5


Long walks in Snowdonia/Eryri (8-11 miles)

View of the Mawddach Estuary

Mawddach Estuary Walk

The aforementioned Mawddach Estuary (see Barmouth Panorama walk) is a spectacular mountain-framed waterway that gushes past a string of pretty Snowdonia villages. Ending in Barmouth, at the mouth of the Afon Mawddach, this 9.5-mile hike follows the course of a disused railway line that runs from Dolgellau to Morfa Mawddach. Follow it through the Arthog Bog RSPB Nature Reserve, past marshes, forests and mountains, and take in long vistas over estuary sands as you go. Take some time to explore Barmouth at the end of the walk, then catch the bus back to Dolgellau.

Distance: 9.5 miles

Difficulty: Moderate

Stay nearby: East Hay Barn | Sleeps 4 + 1 dog


View from Mount Snowdon

Snowdon/Yr Wyddfa by the Miner's Track

We couldn’t do a round-up of the best hikes in Snowdonia without including the ascent up to its highest peak - the ultimate thing to do in Snowdonia! But first, a warning: climbing Snowdon is tough. There are six different routes up to the 1,085-metre summit, many with treacherous scrambles, but the Miner’s Track has slightly better terrain than most. The path was originally built for transporting copper from the Britannia Copper Works, until mining ended in 1916 - lookout for remains from its glory days as you walk. Park at Pen-y-Pass car park and follow the path up past lakes and over craggy ascents to Yr Wyddfa's/Snowdon’s lofty peak, then revel in the panorama.

Distance: 8 miles

Difficulty: Challenging

Stay nearby: Llenfa | Sleeps 4 + 2 dogs
