Buckden Marina sits on the eastern bank of the River Great Ouse in Cambridgeshire, roughly 15 miles along the canalized section of the river and just below Offord Bridge — a low crossing that marks the practical upstream limit for many larger craft.

Set within 92 acres of countryside near the village of Buckden and the town of St Neots, the marina provides direct access to the Great Ouse's 75-mile navigable length, along with its tributaries — the Cam, Lark, Little Ouse, and Wissey — totalling around 140 miles of waterway.

The marina offers 240 floating pontoon berths behind security barriers. It is a popular base for exploring the quieter upper reaches of the river between Buckden and St Ives, a stretch noted for its uncrowded, unspoilt character.
