The walled medieval town of Tenby has four beaches — North, South, Castle, and Harbour. Blue Flag sands, a walled town full of painted Georgian buildings, and Caldey Island boat trips make it Wales's finest resort.
Tenby is a medieval walled town on the southwestern tip of Pembrokeshire in Wales, set within the Pembrokeshire Coast National Park - the only UK national park whose boundary is predominantly defined by the coastline. The town sits on a narrow rocky headland and has four distinct beaches, each with its own character and suited to different visitors. North Beach is the longest of the four, stretching more than a mile northward along Carmarthen Bay from the base of the town walls. It is broad, flat, and sandy with gentle surf and Blue Flag status, making it the most popular choice for families. The sand is pale and firm, and the water is a cool blue-green with good clarity in calm conditions. Lifeguards patrol North Beach from May to September. South Beach extends two miles south from the town toward Penally, offering firm sand backed by low dunes. It faces southwest toward the open sea and receives slightly more wave action than North Beach, making it popular for open-water swimming, kite flying, and bodyboarding. Castle Beach is the most dramatic of the four: a cove directly below the medieval castle ruins and Town Walls, accessible by steps from the clifftop and filling dramatically with the substantial Pembrokeshire tides. It is best visited within two hours of low tide when the full beach is exposed. Harbour Beach occupies the small sheltered sandy bay inside the working fishing harbour, calm and safe for very young children on most days. Caldey Island - a small island three miles offshore, home to a community of Cistercian monks who produce perfume, chocolate, and shortbread - is reached by seasonal boat trips from the harbour. The walled medieval town adds significantly to the appeal: rows of painted Georgian townhouses in pastel colours, independent restaurants serving locally caught crab and lobster, and a working fishing harbour. Tenby Railway Station, served by trains from Swansea and Cardiff, is a ten-minute walk from the main beach access points.

Tips for visiting
- The main car parks within the town walls fill rapidly on summer weekends; the park-and-ride on the A478 is the recommended approach for drivers.
- North Beach is less crowded at the far northern end beyond the main access steps; a short walk along the sand finds quieter stretches.
- Caldey Island boat trips operate from Easter to October, taking approximately 20 minutes; morning departures are calmer as afternoon winds can build.
- The tide goes out a very long way at Castle Beach - check tide tables and arrive within two hours of low tide for the best beach access.
- South Beach is better for kite flying and open-water swimming; North Beach is calmer and more suitable for families with young children.
- Fresh crab and lobster are available from the fishermen's stalls at the harbour - among the most affordable fresh seafood on the Welsh coast.
When to visit
July and August are peak season and the warmest months for swimming. Late May to June and September are often drier, less crowded, and still warm enough for the beach. Tenby's painted town and harbour are appealing year-round, with Christmas and Easter periods also drawing significant visitors.
