Waterwynch Bay is a small cove about ¾ mile north of Tenby. Access is a walk of about ½ mile along a public footpath (mostly a private road) from the A478 Tenby road just south of New Hedges. There is parking for a maximum of 2 cars at this end of the lane. As Waterwynch is a small, quiet beach there is usually space here. Alternative access is from Tenby via the coastal path. Dogs are allowed at all times.
The beach is sand with a pebble bank and a small stream running down the north side. Waterwynch House sits in the narrow valley directly behind the beach, and the upper part of the shore (above the mean high-tide mark) is owned by that estate. The cliffs are of sandstones and mudstones, and there are further coves in both directions which can be reached at low tide. The ones to the north are the best, with sand, rocks, rock-pools and caves. The coves to the south can only be accessed on very low tides, and (in the direction of Tenby) are rather unimaginatively named Second Beach and First Beach.
Normally there is only one way on and off Waterwynch beach - there is no way up to the coastal path from any of the coves on either side, and walking to the neighbouring beaches of Monkstone or Tenby is only possible on exceptionally low tides.
