Carew Castle was built in the late 11th century by the constable of Pembroke Castle, Gerald de Windsor. Archaeologists have found traces of an Iron Age settlement near the castle, as well as Roman pottery. (Pembrokeshire Coast National Park)

The first mill in Carew dates from 1542. The current building probably dates from the early 19th century and has been restored by the National Park Authority, which leases the castle and tidal mill. (Pembrokeshire Coast National Park)

Great to get the old mill techniques explained. Unfortunately we didn't have enough time.

£20 for a bit of ruin is relatively high. Along with the Tide Mill it was okay. If you only want to do a short hike, just walk past the outside...you can also go to the mill.

Tenby's harbor offers a friendly welcome to all walkers (and other guests) with its brightly colored house fronts. Even with drizzle - which is said to happen every now and then in Wales - a beautiful sight!

The castles in the East Williamston area are rich in history, with some dating back to the 11th century. For example, Carew Castle was built in the late 11th century by Gerald de Windsor and is considered one of South Wales' finest. St Catherine's Island and Fort features a fort built during the Napoleonic Wars, showcasing military history.
Many castles in the region are set in scenic locations. St Catherine's Island and Fort is a small limestone outcrop with tidal caves, offering beautiful coastal views. Manorbier Castle overlooks the beautiful Manorbier Beach, and Carew Castle offers views of the Carew River and a millpond.
Some castles, like Manorbier Castle, may have cafes, though they might be closed out of season. It's advisable to check the individual castle websites for current information on facilities before your visit.
Given the region's coastal landscapes, visiting during the warmer, drier months from late spring to early autumn (May to September) is generally recommended for the most pleasant experience. This allows for comfortable exploration of outdoor castle grounds and scenic views.
The East Williamston area offers various outdoor activities. You can find numerous hiking trails, including easy routes like 'Coppet Hall to Stepaside'. There are also MTB trails, such as the 'Narberth loop', and running trails like the 'Amroth Beach loop'.
While the main castles are well-known, the Carew Tidal Mill, located next to Carew Castle, is a unique historical site. It's the only restored tidal mill in Wales and one of only five in Britain, offering a fascinating glimpse into industrial heritage.
For a comprehensive visit to a major castle like Carew Castle or Manorbier Castle, allow at least 2-3 hours to explore the grounds, interiors, and any associated exhibitions. Shorter visits of 1-2 hours might suffice for smaller sites or if you're combining multiple locations.
Visitors frequently appreciate the historical depth and scenic beauty of the castles. The impressive ruins of Carew Castle and the fairytale appearance of Manorbier Castle are often highlighted. The unique tidal access to St Catherine's Island and Fort also provides a memorable experience.
Accessibility varies greatly between historical sites. While some areas of castles, especially ruins, may have uneven terrain or steps, others might offer more accessible routes. It is recommended to check the specific castle's official website or contact them directly for detailed accessibility information before your visit.
Many historical attractions, including castles, often operate with reduced hours or may close certain sections during the winter months. It's always best to verify the current opening times and any seasonal closures directly on the official website of each castle you plan to visit.
