The structure is supported by 18 steel 'trunks' designed to mimic the appearance of tree bark.
It was designed by Marks Barfield Architects, the same firm responsible for the London Eye.
The walkway's lattice design is inspired by the pattern of silica cells in a diatom.
The entire walkway is built from 400 tonnes of weathered steel.
The height of 18 meters was chosen to place visitors exactly within the canopy layer of the forest.
The steel was specifically treated to create a protective rust-like patina that prevents further corrosion.
The Treetop Walkway is an elevated structure located 18 meters above the ground within the Royal Botanic Gardens, Kew. It extends 200 meters through the canopy of deciduous trees, including lime, oak, chestnut, and beech. The walkway is constructed from weathered steel, designed to oxidize and blend into the surrounding woodland environment over time. Visitors access the platform via a staircase or a lift that serves as the central hub. The structure offers an intimate view of the upper canopy ecosystem, including bird species and leaf-dwelling insects. It provides a unique perspective on the seasonal changes of the temperate forest. The walkway is a permanent installation integrated into the botanical landscape.

Visit on a clear day to maximize visibility of the surrounding gardens from the canopy level.
Bring binoculars if you are interested in birdwatching, as the height offers a unique vantage point.
Use the lift if you prefer to avoid the stairs, especially if you have mobility requirements.
Visiting during high-wind alerts, as the walkway may be temporarily closed for safety reasons.
May close during extreme weather conditions such as high winds or thunderstorms.
No running or jumping on the walkway; be mindful of other visitors in the narrow corridor.
