The sandy stretch of North Beach is dotted with rock pools and overlooked by Tenby town. South Beach has two kilometres of dune-backed golden sands that start from the abandoned fortress on St. Catherine's Island. Harbour beach is small, sheltered and the departure point for trips to Caldey Island, a designated conservation area that is home to birds, seals... and Cistercian monks!
Tenby Harbour is also the place to book mackerel fishing trips, hire out pedalos, banana boats or take to the skies with a paragliding trip - it is possible to spot dolphins swimming through the clear waters.
Tenby was surrounded by a town wall built to keep out a 15th century rebellion - today there are scattered remains that you'll see as you explore. Tenby centre is a maze of tight narrow streets that are pedestrianised in the summer and taken over by al fresco diners taking a rest from exploring the town's quirky tourist shops.
Also in the centre is the National Trust owned Tudor Merchant's House that is a wonderfully preserved example of life when Tenby was a thriving port in the 15th-century. Tenby Museum and Art Gallery, in the remains of Tenby Castle, is worth visiting for its six galleries and for the spectacular views of Castle Beach, South Beach and Caldey Island.
