Broadstone is situated just north of Poole on the south coast of England, about 120 miles south west of London.

Broadstone is approached by turning right off the main Wimborne to Poole road (Gravel Hill) by a roundabout, onto Dunyeats Road or by a second roundabout (Darby's Corner) further down Gravel Hill onto Lower Blandford Road. Along Dunyeats road on the right is Broadstone Middle School.

Opposite the school is the water tower.
