Wales has a varied geography ranging from coastal plains to mountainous regions like Snowdonia. It has over 1,300 km of coastline and many lakes and reservoirs used for tourism, leisure, and hydroelectricity. The main population centers are in south Wales, including the cities of Cardiff, Swansea, and Newport. Wales has a mild climate that is cloudy and rainy, especially in western mountain areas. Notable landmarks include Snowdon, the Seven Wonders of Wales, and many natural beauty spots that contribute to Wales' tourism industry. Maintaining this balance of conservation and sustainable use of natural resources will be important for Wales' future.
