Tree House Birr Castle

Tree House Adventure

Where better to play, than up a tree

All you budding knights and princesses will find yourself lost in a world of imagination in the epic Treehouse Adventure Area. The playground features Ireland’s largest treehouse along with new complimentary play equipment added in 2019.

And while they’re busy in the Treehouse Adventure area, you deserve a coffee and a browse around the gift shop – and everyone’s happy!

For inquisitive family members, they’re in for a treat with our seriously impressive Science Centre. Take a step back in time and visit our historic Science Centre, then go for a stroll around our stunning formal gardens. That’s where you’ll find our famous astronomical wonder; the Great Telescope - arguably the largest historic scientific instrument still working today. There’s a very good reason we call Birr Castle the ‘Demesne of Discovery’. Come visit and you’ll find something for all the family to enjoy.

It’s the perfect spot for an afternoon of fun and adventure. The treehouse is open year round with further details on the seasonal elements available from
