Just west of the village, at the edge of Exmoor National Park, is the Clatworthy Reservoir, which impounds the headwaters of River Tone and supplies water to some 200,000 homes and businesses, some as far away as Yeovil. An Iron Age enclosure known as Clatworthy Castle was sited on the wooded slopes above the reservoir and there are round barrows in the north of the parish.
