Stroll through the treetops

The theme is New Views Of Kew and one of the best places to enjoy them is on the Treetop Walkway, which has a new high tower and extended path through the redwoods and oaks. Concealed cameras along it offer a bird's-eye view to visitors at the bottom.

Another camera, mounted on top of the 50m pagoda, lays the gardens out like a map and reveals the original planning behind the World Heritage Site. Kew's School Of Horticulture has created six ideas gardens - including a 60m planting exploring the language of flowers and a field of opium poppies, grown under special licence.
