There are two settlements named Tunstall next to each other, 7.5 miles (12.1 km) north east of Woodbridge.

The village itself is a good-sized settlement with a pub (The Green Man) and a church called St Michael's, notable for its unusual box pews.

Half a mile away, Tunstall Common has a dozen houses and a Baptist chapel.

Tunstall Common itself is a Site of Special Scientific Interest (SSSI), a fragment of the ancient sandling dry lowland heath that was once extensive across this area of coastal Suffolk.

The adjacent Rendlesham Forest is known for the former RAF Bentwaters site, now in private ownership, and alleged alien sightings in the 1980s.
