Superb architecture, complemented by majestic trees make this walk (one of two) one of the most beautiful and intriguing in the town. View some of the architect Edmund Elmslie’s best work, locate the Bhutan Pine, imagine life in ancient times, understand the history of Swan Pool. View Britain’s best Oriel, Lebanon Cedar and internationally recognised ‘handkerchief tree’. Meet a tree that helped Greek armies dominate the known world.

The second, slightly more vigorous walk, MWF24, takes place on Sunday 28th.
