Adventure Birthdays

There is adventure to be found all around Earth Trust Centre! From woodland and wildflower meadows, to rivers and wetlands, we make the most of these glorious green places, full of heritage and wildlife, to create exciting experiences that encourage children to explore and discover, and make memories that last a lifetime.

Flexible spaces, inspired by nature


Nestled at the foot of the iconic Wittenham Clumps, within a designated Area of Outstanding Natural Beauty, Earth Trust Centre is bursting with life and full of nature.

All around Earth Lab, our new, eco building, birds and swallows swoop and red kites soar overhead, the scented herb garden attracts butterflies and bees, and you might even spot a barn owl swooping low at dusk.

You’ll enjoy exclusive use of our entire learning space, including the picnic area, kitchen garden and the Earth Lab atrium for your birthday event. It’s a totally flexible indoor and outdoor space for all kinds of parties that work in any kind of weather.

The enclosed gardens provide an ideal, safe space for play and feasting, with plenty of quiet places for a relaxed chill-out area if needed.

We have free on-site car parking and all our spaces are wheelchair accessible. There are outdoor and indoor toilets and hand washing facilities.

Earth Lab Atrium

Convenient location

We have all the wide open spaces of the countryside you could wish for around us, with the convenience of a South Oxfordshire location, just 11 miles from Oxford, 18 miles from Reading and with easy access to the M4 and M40.

Sustainability at our heart

As an environmental charity, sustainability is naturally at the heart of everything we do. A biomass boiler heats our spaces, we harvest rainwater and solar panels generate electricity.
