[4] Mountain River, a tributary of the Huon River, flows from north-east to south-west through the northern part of Grove, and then forms much of its western boundary.
[5] Most of the part of Grove southeast of the Huon Highway (12.7 km²) is hilly and remains forested, whereas most of the part northwest of the Huon Highway (18.1 km²) is undulating and cleared for agriculture - chiefly grazing and orchards.
The Huon Highway (route A6) enters from the north-east from the direction of Hobart and runs through Grove to the south-west, where it exits towards Huonville.
Route C618 (Crabtree Road) starts at an intersection with C617 and runs north-west until it exits Grove.
Route C619 (Lollara Road) starts at an intersection with A6 and runs west until it exits, eventually following the left bank of the Huon River, then the right bank, downstream to Huonville.
