Cefn Sidan, Sandy beach in Carmarthenshire, Wales.
Cefn Sidan is a sandy beach in Carmarthenshire stretching across several kilometers along Carmarthen Bay with fine sand and extensive dune formations. The shoreline lies between two port towns and offers broad coastal areas for visitors to explore.
The beach witnessed several shipwrecks over the centuries, with notable vessels running aground during the 1800s and 1900s. Treacherous sandbars near the coast created hazardous conditions for maritime traffic.
The beach draws locals and visitors who come to walk along the shore and enjoy the open coastal landscape. Families and swimmers gather here during summer, making it a social gathering place for the community.
The beach has multiple access points making it easy for visitors to find a convenient entry to the shore. Swimmers can expect supervised areas during warmer months and facilities designed for safe water activities.
The sand here has an unusually fine grain composition that makes it nearly impossible to build lasting sand structures or castles. Visitors often discover this surprising quality only after attempting their first creations.
