Founded by Charles Darwin's mentor, Professor John Henslow, the beautiful Botanic Garden is home to 8000 plant species, a wonderful arboretum, glasshouses (containing both fierce carnivorous pitcher plants and the delicate slipper orchid), a winter garden and flamboyant herbaceous borders. The gardens are 1200m south of the city centre via Trumpington St.

Hour-long guided tours (free) are held at 3pm on Sunday in May, June and July, and on the first Sunday of the month in March, April, August, September and October.
