Halloween in Mid Wales

Halloween in Mid Wales falls in the middle of October half term, when evenings are dark by six and the hills have turned brown and copper. Across Powys, Ceredigion and Southern Eryri (Southern Snowdonia), heritage railways run evening ghost trains, attractions put on family trails, and there are enough old stories in the hills and gorges to keep everyone talking on the walk back.

In Wales, the night of 31 October has its own name: Nos Calan Gaeaf, the eve of the first day of winter. It was traditionally a night for bonfires, fortune telling and staying away from churchyards. Some of that has survived, and some of it has been swapped for pumpkins.

Ghost trains and evening rides

The Bala Lake Railway runs Halloween Trains on 30 and 31 October 2026, with two evening departures from Llanuwchllyn at 5:30pm and 6:45pm. The train heads along the shore of Llyn Tegid in the dark before things go wrong, with ghosts and witches waiting at the halts on the way back. Details are on the Bala Lake Railway Halloween Trains listing, and dressing up is encouraged.

The Talyllyn Railway near Tywyn in Southern Eryri has run its Steam and Scream evenings in past years, with an unlit train to Dolgoch Woods and a walk through the trees with some unexpected company. Check the railway's own dates for 2026 before you plan around it.

Underground and after dark

For children who like to be a little bit scared, the slate caverns at Corris near Machynlleth are hard to beat. King Arthur's Labyrinth takes you by boat through an underground waterfall into caverns where Welsh legends are told in the dark, and Corris Mine Explorers leads guided trips into a Victorian slate mine that looks as if the miners left yesterday. Both are good on wet days.

In Ceredigion, the Silver Mountain Experience near Aberystwyth is set in an old lead mine and has run Halloween events over half term in previous years. Check what's on for 2026 before you go.

Legends and spooky walks

Mid Wales has plenty of stories to tell on a dark walk. At Devil's Bridge in Ceredigion, the legend says the Devil built the first bridge across the gorge in exchange for the first living thing to cross it, and an old woman sent her dog over first. The Mynach Falls are loud and the gorge is dark under the trees in October, which helps.

Castles look different in autumn too. Powis Castle near Welshpool in Powys sits on its rock above the terraced gardens, and Cardigan Castle on the Teifi in Ceredigion has centuries of history behind its walls. Check each for Halloween opening and events.

Is Halloween a good time for a family break in Mid Wales?

Yes. It falls in October half term, so most attractions are open, the weather is often mild, and the evenings are long enough for ghost stories without keeping small children up too late. Look at our family events for pumpkin trails, craft sessions and half term activities, and our half term guide for daytime ideas.

Where to stay for Halloween weekend

A cottage with a wood burner is hard to beat after a cold evening out. Look at family-friendly places to stay, or somewhere with open fires and log burners. Half term weeks fill early, so check your dates soon.
