SINCE 1971

In the heart of Wales, just off Bannau Brycheiniog (formally the Brecon Beacons) you’ll find the Tyr Abad mansion (how fancy) backing onto more than 1500 acres of open access foresty.

Historically rich and in a visually stunning location, our centre is self-contained and provides dorm-style accommodation for groups of up to 50 people. So, whether you’re planning a stag or hen do, your grandparent’s 50th wedding anniversary, or a workshop for your dream business, the space is designed for the cost-effective delivery of courses, expeditions, and gatherings.

In 2023, our home was fully renovated and redecorated to retain a homely charm whilst updating all the facilities which include:

• 9 Dorm rooms (of which 2 are ensuite)
• 2 Large shared washrooms
• Commercial kitchen
• Large dining room
• Changing / drying room
• Classroom

Adrenaline-fueled adventure or silent retreat: A Centre for all groups & ages

beautiful dinning room with old oak benches and long tables designed to look magical like the harry potter hall.

The centre grounds are well-equipped for:

  • Orienteering
  • Problem-solving
  • Archery
  • Bushcraft

And, the local area is ideal for field studies in geography,
geology, and life sciences. It is also located within the International Dark Skies Reserve.

planning for the future

Part of ARC’s ethos, and therefore Tyr Abad‘s, is pushing to lead a lifestyle that supports the environment as well as the future of the centre. This has included in two major investments within the 2023 renovations: A borehole, for its own water supply and a biomass boiler which runs off woodchip and covers the entire site’s central heating system and hot water.

Some of the finest practice I have seen in over 20 years of working with children with challenging behaviour. This skill set means the levels of engagement we see from our boys is excellent in the fantastic range of activities on offer. At all times Pete’s delivery of activities is first class and the pupils want to succeed in areas most have never experienced before.

I cannot recommend Arc Adventures enough for all children but particularly those that present with SEMH and behaviour that challenges. It is a life changing experience for our pupils in an environment which provides safety and support.

Excellent and never to be forgotten! Push yourself to new heights.

The care and compassion shown by Peter and all the crew was amazing… there was a community spirit throughout, with a night walk and camp fire to make our days complete. It brought back happy memories staying in the YHA…

It was fantastic to be pushed physically, refreshed mentally and to forget about work and the worries of life.
