Rainy Day Things to Do Near Builth Wells: A Wet-Weather Guide for Your Mid Wales Holiday

Here is the honest truth about the Cambrian foothills: they are green because it rains. If you book a holiday cottage near Builth Wells in autumn or winter, you will almost certainly get at least one day when the cloud sits on the hills and the rain sets in. We live here, and we would rather tell you that now than have you discover it on day two.

The good news is that some of the best things to do near Builth Wells are better in the rain, and most of the rest carry on regardless. Red kites still come to feed. Reservoirs overflow. Waterfalls that are a trickle in August become worth the drive. And a wet afternoon is a perfectly good excuse for a film, a museum, or two hours in a bookshop.

This guide covers rainy day things to do near Builth Wells, grouped by how far you want to drive. Everything here was checked in October 2026. Opening times in rural Mid Wales change with the seasons and sometimes at short notice, so please check before you set off. We have flagged the places that close for the winter.

Before You Set Off: Three Rules for a Wet Day in Mid Wales

Check opening hours on the day. Small museums, heritage centres and arts venues here are often run by volunteers or small teams. Winter hours are shorter, and some places close entirely between November and Easter.

Watch the water on minor roads. The single-track lanes west of Beulah cross streams on low bridges, and after heavy rain some of those crossings flood. If you are unsure, stick to the A483 and A470 and leave the mountain roads for a dry day.

Pick one big thing. A wet day goes better with one proper outing and a slow return to the cottage than with three rushed stops in the car. Rain also makes the light go early in winter, so plan to be back before dark.

Close to Home: Builth Wells and Cilmeri

Builth Wells is about 11 miles from Graig Fawr, and it is where most rainy days start, if only for supplies.

Wyeside Arts Centre

Wyeside is a Grade II listed building on Castle Street with a cinema and a small theatre under one roof. It shows recent releases alongside live screenings and touring productions, and there are drinks and snacks in the foyer. It is open most evenings from Tuesday to Friday and for afternoon and early-evening screenings at weekends, and closed on Mondays. Check the programme on the Wyeside website before you go, because screenings change week to week.

A matinee on a wet afternoon, followed by fish and chips or a pub supper in town, makes a good rainy day in its own right.

Builth Wells Heritage Centre

The Tourist Information and Heritage Centre on the High Street is run by the Builth Wells and District Heritage Society. It is small, but it is the place to understand the town: old photographs, local memorabilia and books on the area. It is also where you can pick up the Society’s Popular Walks leaflet for a dry day later in the week. It opens mornings only, Monday to Saturday.

The swimming pool

Builth Wells Sports Centre and Swimming Pool on College Road has a public pool and gym. Public swim times are on the operator’s timetable and change through the week, so look them up before you pack a towel. Getting wet on purpose is surprisingly cheering when it is pouring outside.

The Llywelyn monument at Cilmeri

On the A483 between Graig Fawr and Builth, a granite memorial marks where Llywelyn ap Gruffudd, the last prince of an independent Wales, was killed in 1282. It is a short stop rather than an outing, and it is outdoors, but it takes ten minutes and you can do it between showers. It pairs well with our guide to the ancient history of Llanafanfawr, on your doorstep.

Red Kites in the Rain: Gigrin Farm, Rhayader

If you only do one thing on a wet day, make it this. Gigrin Farm, half a mile south of Rhayader and about 10.8 miles from Graig Fawr, is a working sheep farm that has fed wild red kites every day for decades. Hundreds of birds come down to the field at feeding time.

The reason it works so well in bad weather is the hides. There are five covered hides, three of them with ramp access, plus photography hides. You sit dry and watch through the open front as the kites wheel and drop. There is a coffee shop and a shop on site.

From late October to late March, feeding is at 2pm. From late March to late October it moves to 3pm. The farm is open all year apart from a few days around Christmas, and there is an admission charge. Arrive half an hour early so you can settle in before the birds arrive.

We have a full guide to watching red kites at Gigrin Farm. On a clear day, it is worth knowing that guests often see red kites from the patio at Graig Fawr without going anywhere at all.

The Elan Valley in Wet Weather

The Elan Valley is 10 to 15 miles north of Graig Fawr, past Rhayader. Most people think of it as a sunny-day place for cycling and walking. In fact, heavy rain is when it puts on its biggest show.

The dams overflowing

The Victorian dams were built to hold back water for Birmingham, and after sustained rain they overspill. Caban Coch, the dam nearest the visitor centre, turns into a wide curtain of white water, and you can feel the spray from the bridge below it. Garreg Ddu and Craig Goch further up the valley overflow too. The staff at the visitor centre have said that in winter all the dams overflow.

It is loud, wet and impressive. Take a waterproof and do not expect to stay long.

The visitor centre

The Elan Valley Visitor Centre, about three miles from Rhayader, is open all year with shorter winter hours. Inside there is a display on the valleys and the building of the dams, which is a remarkable story of Victorian engineering. The café looks out over Caban Coch. It is the natural place to dry off after the dam.

See our guide to the Elan Valley reservoirs and trails for the rest of the valley on a drier day.

Museums in Llandrindod Wells and Rhayader

The Radnorshire Museum

On Temple Street in Llandrindod Wells, the Radnorshire Museum is free and covers geology, archaeology, natural history, social history and art from the old county. It is closed on Wednesdays and Sundays and has shorter Saturday hours between October and March. It is a good hour indoors, and Llandrindod has cafés for the rest of the afternoon.

The National Cycle Museum

Also on Temple Street, the National Cycle Museum holds around 250 bicycles covering two centuries of cycling. It is seasonal. Its published opening runs from April to the end of October. If you are visiting in late autumn or winter, contact the museum before making the trip.

TimeScape, Rhayader

TimeScape is a local museum and gallery on East Street in Rhayader, with interactive displays on local history, nature and folklore. It is also seasonal. It is open Thursday to Saturday from Easter to 1 November, then closes for the winter. If you are here in early autumn, combine it with the 2pm kite feed at Gigrin.

A Longer Wet Day: Brecon and Hay-on-Wye

If the forecast says rain all day and you want a proper day out, two towns to the south and east are worth the longer drive.

Y Gaer, Brecon

Y Gaer occupies the old Shire Hall on Glamorgan Street. Under one roof you get the Brecknock Museum and Art Gallery, a preserved Victorian courtroom, the town library and a café. It is open seven days a week. The courtroom alone is worth the visit.

Brecon Cathedral is a few minutes away and open daily, with a café and bookshop in the grounds.

Hay-on-Wye

Hay-on-Wye, about 45 minutes from Graig Fawr, has more than 20 bookshops, and a wet day is exactly what they are for. Richard Booth’s Bookshop on Lion Street is the best known, open daily except Christmas Day, Boxing Day and Easter Sunday, and has its own small cinema on Brook Street. Our guide to staying for Hay Festival covers the drive and the town.

Waterfalls That Need the Rain

Some places are better after a wet spell. If it has rained for a few days and stops for an afternoon, these are the ones to go for.

Water-break-its-neck, near New Radnor

Natural Resources Wales manages this waterfall in Warren Wood, about a mile south-west of New Radnor off the A44. It is a short there-and-back walk of 20 to 30 minutes from a free car park into a narrow, mossy gorge with the fall at the end. Natural Resources Wales notes that it is at its best after a few days of rain. The postcode will not take you to the car park, so use the grid reference SO 186 597. It is roughly 45 minutes from Graig Fawr.

Henrhyd Falls

Henrhyd, owned by the National Trust near Coelbren, is the tallest waterfall in South Wales at around 90 feet. It is over an hour away, so it is a full outing rather than a quick stop. The path is steep, with steps that are slippery after rain, so wear proper boots.

And If You Would Rather Not Go Anywhere

There is a lot to be said for doing nothing on a wet day. Graig Fawr has a sitting room with a large bookcase, a Smart TV and reliable wifi, and the underfloor heating runs throughout the barn, powered by the farm’s air source heat pumps and solar panels. The floors stay warm however grey it is outside.

Rain on the 40 acres is worth watching too. The wildlife pond fills and the birds on it carry on regardless, and the meadows smell completely different after a downpour. If it eases off for an hour, the mown trails across the farm are right outside the door, so a short walk needs no driving. Bring proper boots, because the ground gets soft quickly.

This is part of why we think of Graig Fawr as an all-weather holiday cottage. It does not rely on a hot tub or a sunny terrace to make a holiday work. We wrote more about that in why Graig Fawr has no hot tub.

Why Graig Fawr Works as a Base When the Weather Turns

Graig Fawr is a stone barn holiday let for two on our 40-acre conservation farm at Llanafanfawr, near Beulah. For rainy days, the location matters. You are about 11 miles from Builth Wells and around ten miles from Rhayader, so the cinema, the kites, the Elan dams and the museums above are all within reach without a long drive in poor weather.

The barn itself is built for coming back to on a wet day. Two dogs are welcome at no extra charge, and there is space by the door to deal with muddy boots and paws. The kitchen is fully equipped, so a long, slow supper is easy, and the washer/dryer means wet clothes are not a problem by morning.

It suits a short break of two or three nights as well as a week. A longer holiday also means one wet day does not cost you much, because there will be a dry one along soon. If you are weighing up how long to come for, our guide to trip length may help.
