The Western Cleddau is a river in Pembrokeshire, West Wales, forming part of the broader Daugleddau estuary system where it joins the Eastern Cleddau and two other rivers. The river has both an upper whitewater section and a lower tidal estuary character, with the Welsh Canoe Classics guidebook listing the Western River Cleddau as a whitewater (WW) route distinct from the Daugleddau Estuary paddle.

The tidal lower reaches are accessible from several launch points. Landshipping and Picton Point are noted as good launching spots for exploring both the Eastern and Western Cleddau. The tidal nature of the waterway means that different trips are achievable at different times and on different days, so planning around the tide is essential. The estuary can be paddled at all levels of the tide, offering flexibility for trip planning.

The landscape along the river is characterised by steep wooded banks, ancient oak woodland, salt flats, and marshes. Notable stopping points in the wider estuary system include Lawrenny Quay, Cresswell Quay, and Carew Tidal Mill. The area supports a wide range of wildlife, including herons, kingfishers, diving grebes, egrets, otters, and wading birds. Occasional seals have also been reported in the estuary.

The river and estuary are sheltered from easterly winds, which can be a practical advantage when coastal conditions are unfavourable. The quiet, largely undeveloped riverbanks and the presence of historical riverside architecture contribute to the overall character of the paddling experience.

Access to inland waters in England and Wales does not carry unequivocal legal rights, and paddlers are advised to check the current access situation before embarking on a trip, as landowner permissions can change. The tidal nature of the lower river also means that trip logistics, including shuttle arrangements, require advance planning. Guided canoe tours of the upper Daugleddau estuary are available through local operators, with tours typically lasting around three hours, and bespoke longer trips can be arranged on request.
