Westleton Heath National Nature Reserve is 0.5 miles (1 km) north east of the village.

The heath is crossed by a minor road from Westleton to the coastal village of Dunwich, 2 miles (3 km) to the east.

The fourteenth-century village church of St Peter in Westleton was built by monks from Sibton Abbey near Saxmundham.

The church has twice seen the collapse of its tower: in 1776 under the strain of hurricane winds; and during World War II, when the smaller wooden replacement had to be demolished following bomb damage.
