Moffat's topography is defined by a contrast between its valley-floor town site and the steep, expansive uplands beyond.
- **Town setting:** Moffat sits in the valley of the River Annan on comparatively gentle ground suitable for settlement and transport. - **Surrounding hills:** The nearby **Moffat Hills** rise sharply and create a classic Southern Uplands profile of rounded summits, broad ridges, and moorland plateaus. - **Highest nearby point:** In the surrounding district, **White Coomb** is one of the most prominent high summits, reaching about **821 m (2,694 ft)**. - **Notable waterfall and corrie terrain:** **Gray Mare's Tail** descends from upland terrain shaped by glacial processes, with steep slopes and a corrie landscape around **Loch Skeen**. - **Lowest local areas:** The lowest ground in and immediately around town follows the River Annan floodplain. - **Flood plains:** As with many river valleys, land beside the Annan is lower and more prone to drainage and flood-management concerns than the surrounding terraces. - **Coastal areas:** Moffat is inland and has no coastline. - **Canyons or plateaus:** The area has no major canyon landscape, but upland ridges and moorland plateaus are important local landforms.
Overall, the topography makes Moffat visually distinctive: a compact settlement at the foot of much larger upland scenery.
