Holt Island is beautiful green and tranquil space on the river Great Ouse St Ives. It is predominantly wet woodland (a rare local habitat) and supports a wide range of typical flora and fauna. Two areas have been replanted with osier (willow) to reintroduce the traditional craft of cultivating and working with willow.
The reserve has a circular boardwalk with seating plus an interpretation centre and picnic tables. There are lovely views across the flood meadow and towards the town bridge.
Holt Island Nature Reserve is open on weekends and bank holidays from Easter until October. At other times keys are available from the Norris Museum and One Leisure. It is located behind All Saints Church on The Waits, a short walk from the bus station.
