Llanegwad sits on the banks of the river Tywi between Carmarthen and Llandeilo in Carmarthenshire, South Wales. The Cothi river, the largest tributary of the Tywi, runs to the north of the village. Both rivers are noted for their excellent trout and sea trout fishing.

The village has Medieval origins but most of the present buildings belong to the 18th and 19th and 20th Centuries. Llanegwad parish church was built in the 10th or early 11th Century and rebuilt in the mid 19th Century. There are several fine commemorative plaques inside the church. The tower was built to the memory of Margaret Bath but, as with much of the church, is sadly in a poor state of repair.

The National Botanic Garden of Wales, 9.1km from Llanegwad, attracts many visitors throughout the year. The garden includes a tropical house, Japanese house, Mediterranean garden, Wild garden, a 'Roots and Shoots' Adventure Zone for children, and three lakes which are home to an array of geese, ducks, coots and moorhens. However, the main attraction is the Great Glasshouse, which sits quietly in the centre of the garden. It may look like a huge bubble has just landed in the garden, but the glasshouse is in fact a huge greenhouse housing plants from six areas of the world: the Mediterranean Basin, Chile, California, Australia, the Canary Island and South Africa. An art gallery can also be found in the garden.
