Pakefield to Easton Bavents is a 735.4-hectare (1,817-acre) biological and geological Site of Special Scientific Interest which stretches along the Suffolk coast between Lowestoft and Southwold.

[1][2] It includes three Geological Conservation Review sites,[3][4][5] and part of the Benacre National Nature Reserve.

[6] An area of 326.7 hectares is the Benacre to Easton Bavents Lagoons Special Area of Conservation,[7][8] and 470.6 hectares is the Benacre to Easton Bavents Special Protection Area under the European Union Directive on the Conservation of Wild Birds.

[9][10] The site is also partly in the Suffolk Coast and Heaths Area of Outstanding Natural Beauty.

[11] The site is described by Natural England as nationally important for its exposures of the Lower Pleistocene Norwich Crag Formation, its vegetated shingle features, saline lagoons, flood-plain fens, its nationally scarce vascular plants, and for its scarce breeding birds and wintering bitterns.
