Llys-y-frân Country Park and Reservoir which is managed by Dwr Cymru Welsh Water. In the 1970s the Llys-y-frân valley was dammed to form a large freshwater reservoir holding most of Pembrokeshire’s water supply. Small streams and rivers flow into the reservoir from the surrounding catchment, including the Afon Syfynwy, which flows via the smaller Rosebush reservoir situated a few miles to the north-east. The Syfynwy river flows through the reservoir and onwards over the dam at the south end of the reservoir to join the Eastern Cleddau river at Gelli, the next stop on the Cleddau Trail.

More information about the Country Park and activities is available from www.llys-y-fran.co.uk web site.



The reservoir is located in the village of Llys-y-frân near Clarbeston Road in mid Pembrokeshire, well-signposted from all directions.



There are accessible routes to the end of the reservoir and cafe, although rutted and stoney forest tracks around the reservoir are rutted in places.



There are toilets and a café here.


Activities and Places of interest nearby

Llys-y-frân country park needs a good day to explore and enjoy the walks, wildlife and water activities such as angling and boating, and the café offers great food. Facilities include toilets, bike hire, parking (pay and display) and birdwatching from bankside hides. Fishing permits are sold at the cafe, for bank or boat angling for rainbow trout which thrive in the clear deep water of the reservoir, but there’s no chance of catching any migratory fish here as Salmon and Sewin cannot leap up the dam!
