Days Out: Centre for Alternative Technology, Powys

The venue

Tucked beneath the southern peaks of Snowdonia National Park is the UK's most eco-friendly visitor attraction. The CAT centre opened in 1975, but its remit couldn't be more current: to demonstrate how everyone can live more sustainably. The centre leads by example - almost all of its buildings and displays are powered by solar, wind or hydro energy and you can try out its waterless toilets. Even access to the site is environmentally friendly: visitors enter via a steep, water-balanced cliff railway.

For children

Kids can bang the plastic pipes and barrels of the "rubbish orchestra"; push the buttons and knobs in the alternative power zone; then scramble around the mole hole - a dark, underground tunnel with giant creepy crawlies. If the displays don't keep them busy, the centre also has two adventure play areas, and a smallholding with goats, hens, ducks and geese. In the garden areas children are encouraged to test out fragrant and tasty plants and herbs in the "taste me" and "smell me" beds.

For adults

Gardeners at the centre have had years of experience transforming what was once a barren slate quarry into fertile, organic gardens. Visitors can learn how this was achieved and pick up tips for their own gardens through the displays on composting, natural pest control and urban gardening, which proves that useful crops can be grown even in the smallest of spaces. The ultra eco-friendly Whole Home building also offers some great advice on how to green up your own home.

Refreshments

The self-service restaurant serves vegetarian, vegan and gluten-free meals, using ingredients grown at the centre or sourced locally.
