The village is set in a valley, with the rolling hills and burns on both sides, covering some fifty square miles.

The Parish Church of Tweedsmuir was built with Scottish red sandstone in 1874 on site of earlier 1643 structure.

The 22 MW Glenkerie wind farm of Infinis is located five kilometres (three miles) northwest of the village.

While work on the railway and the reservoir was in progress, a large number of workmen lived in Tweedsmuir, dramatically increasing the population.

The large company was brought from Edinburgh in two special trains, which were hauled for the last stage of the journey, from Broughton Station, by small service engines on the Talla railway.
