Cuttle Brook is a tributary of the River Thame and this local nature reserve, opened in 1995, covers about 30 acres of wet grassland flood plain. This habitat is becoming nationally scarce and the Cuttle Brook reserve offers superb, open river-meadow views and a network of paths through mixed meadows, young woodland, sedge and reed beds, hedges, trees, riverbanks and scrubland. There are several entrances to the reserve, which is just a few minutes walk from Thame town centre, and a picnic area.
