Black Mountains, the range of mountains on the far western part of the Brecon Beacons National Park falls within Carmarthenshire. This part of the Brecon Beacons is far less visited than the central and western parts but is no less spectacular.
National Botanic Garden of Wales at Llanarthne, west of Carmarthen, was created in the new millennium and features over 100,000 plants set in a 568-acre regency park. Includes the world's largest single span glass house.
