Tenby sits on a rocky headland in South Pembrokeshire, framed by three distinct stretches of golden sand. This walled town is famous for its rows of pastel-coloured houses that overlook the small fishing harbour. My top tip is to board a boat to Caldey Island. You can visit the Cistercian monastery and see the white lighthouse for a fee. The medieval town walls remain mostly intact, with the Five Arches gate serving as a grand entrance. The Tudor Merchant's House reveals a glimpse into local life during the fifteenth century. Castle Hill provides a panoramic view across the water toward St Catherine's Island. The scent of salt spray mixes with the smell of fresh fudge from the high street. Life here centres on the tides and the vibrant maritime history of the coast.
