Discover why October is a brilliant time to explore Snowdonia (Eryri), with scenic low-level hikes, atmospheric summits, and quieter trails across the national park.
October in Snowdonia (Eryri) is something special. The crowds have thinned, the valleys glow with autumn colour, and the light seems to sharpen the edges of every peak. It’s a month of change, one foot still in autumn, the other edging toward winter. That mix makes it one of the most atmospheric times to head for the hills.
The shorter days and shifting weather mean the big days out need a little more planning, but in return, you get a quieter, more dramatic landscape. Bracken turns copper, clouds roll quickly over ridgelines, and even the most familiar trails feel fresh again. Whether you’re looking for a low-level wander or a final summit push before the seasons change, Snowdonia has plenty to offer this time of year.
Snowdonia’s variety is what makes it a great October choice. It has quiet valleys and dramatic mountains, short circuits and full-day outings to work around weather and daylight.
Many popular paths are quieter midweek, and the honeypot routes become more enjoyable with fewer boots on them. You can still get a good forecast window, particularly early in the month, and there’s something deeply satisfying about topping out on a quiet ridge in a woolly hat while the rest of the country is sitting indoors.
Facilities in places like Llanberis, Betws-y-Coed, and Beddgelert remain open well into autumn, making access easy for weekenders and spontaneous day-trippers alike.
A Snowdonia classic that’s often quieter than it deserves to be. This Grade 1 ridge walk is just technical enough to feel adventurous without needing ropes or nerves of steel. In October, the rough textures of the Daear Ddu ridge catch the low sunlight beautifully, and if the weather turns, you can always retreat down the lake path.
If the tops are clagged in, Cwm Idwal is a perfect mid-level escape. The path around the lake is stunning in autumn framed by golden grasses and steep crags. For those with the time and legs, the Devil’s Kitchen offers a steep but rewarding climb up to the Glyderau ridgeline, where you’ll often find frost underfoot and quiet summit cairns.
October is one of the best times to climb Yr Wyddfa (Snowdon) without the queues. The Snowdon Ranger Path offers a quieter approach with a gradual climb and expansive views over Llyn Cwellyn. Time it early for a chance at a sunrise summit without a single person in sight, a rare experience on Wales’ highest mountain.
The Rhinogydd range feels like a different world rocky, remote, and far less visited. The approach from Cwm Bychan is steep and rugged, but in return you’ll get solitude, old stone walls, and a sense of genuine wilderness. The autumn colours in the lower woodland are brilliant, and the views from the top feel earned.
Starting from the village of Abergwyngregyn, this walk offers the best of both worlds: a low-level approach through golden woodland to the impressive Aber Falls, followed by a longer climb to the Carneddau ridge for those wanting something bigger. If conditions allow, a full loop over Foel-fras gives you a big-day feel without extreme exposure.
Snowdonia in October offers exactly what a walker wants from autumn: space, colour, atmosphere, and a sense of reward. Whether you’re topping out on a final summit before winter or threading your way through an amber-coloured valley, this national park is built for seasonal exploration.
Pick your route, watch the forecast, pack smart and enjoy the hills while the year still has a little light left in it.
