Nine Wells, Cambridge Travel Guide

History and water supply

The springs at Nine Wells have supplied water since at least the Domesday period. In the early 17th century they were channelled into Hobson’s Conduit, constructed between 1610 and 1614, to deliver clean water to Cambridge and flush the King’s Ditch. The conduit remained the city’s principal supply for more than 250 years and still feeds the Botanic Garden lake. An 1861 obelisk commemorates the conduit’s benefactors, including Thomas Hobson. The site later formed part of a biological SSSI until 1976, when drought and abstraction caused the loss of rare glacial-relic invertebrates.

Physical setting and features

The reserve occupies a small plot of woodland, scrub and grassland at the base of the Gog Magog Hills where the land drops from chalk slope to flatter fields. Four main springheads release water at a constant 10 °C, linked by channels that form Hobson’s Brook. Mature beech, ash, hawthorn, spindle and field maple stand beside areas of grassland. Seasonal flowers include violets, bluebells and cowslips. The enclosing hedgerow dates from the 1834 Great Shelford Inclosure. The reserve was designated a Local Nature Reserve in 2005 and a Local Geological Site in 2017.

Visitor experience

Most visitors follow the short, self-guided paths to view the springheads, streams and monument, then watch birds, insects and plants. The compact layout allows a thorough circuit in under an hour, with the option to continue along connecting foot and cycle paths. The atmosphere is quiet and secluded, set between farmland and the expanding Biomedical Campus. Information boards provide context on the geology, hydrology and history. The site suits walkers, nature observers and those interested in Cambridge’s water heritage.

Access and transport

There is no road access or on-site parking. The nearest practical approach is by bus to Addenbrooke’s Hospital, followed by a 10- to 15-minute signed walk along foot and cycle paths. Trains from Cambridge to Great Shelford station take six to eight minutes, after which the walk is 15 to 25 minutes. Cycling via the genome campus and Addenbrooke’s paths takes 20 to 30 minutes from the city centre. Taxi journeys from central Cambridge last 10 to 15 minutes. Paths are for pedestrians and cyclists only; some sections can be uneven.

Facilities and practical notes

Facilities are limited to information boards and the listed monument. No restrooms, drinking water, food outlets or visitor centre are present. Visitors should be self-sufficient. Fires and barbecues are prohibited. The reserve remains open at all times with no seasonal closures, though wet weather makes paths muddy and reduces comfort. Nearest amenities lie at Addenbrooke’s Hospital or in Great Shelford village.

Seasonality and wildlife

Spring brings migrating birds and early flowers; summer highlights nesting birds, dragonflies and butterflies. Autumn and winter visits are quieter, with shorter days and occasional sightings of redwings. The site is managed for habitat restoration, including channel clearance and glade creation, supporting species such as reed warblers, yellowhammers, kingfishers and bullhead fish.
