Westonbirt Arboretum Boundless Member Day

A summer day out among the treetops

Spend a relaxed summer’s day exploring one of the most beautiful and important tree collections in the world, at an exclusive Boundless member price.

Westonbirt Arboretum is home to over 15,000 trees and 2,500 species from across the globe. Set within stunning landscaped grounds, it plays a vital role in conservation and research, while also being a brilliant place for families to explore, unwind and enjoy the outdoors together.

Wander beneath towering canopies, follow scenic woodland trails, and take in the views from the Tree Top Walkway. There’s plenty to keep younger visitors entertained too, from forest play areas and family trails to spotting the Gruffalo hidden among the trees. When it’s time for a break, enjoy a picnic in the woods or grab a bite to eat at the café or on-site restaurant.

Whether you’re after a peaceful escape or an active family adventure, Westonbirt offers something for every age — and your Boundless membership makes it exceptional value.
