Google Review

A haven for birds, walkers, watersports and wellbeing, set in the beautiful rolling landscapes of Monmouthshire south Wales.

Free to enter and open all year round there’s plenty to do for all ages and abilities. A great place to spend the day exploring walking trails, fishing, and with a great range of water and land activities you will be spoilt for choice.

Whatever adventure you choose, enjoy taking deep breaths of fresh Monmouthshire air, where social distancing comes naturally.

Our Story

A large 434 acre water supply reservoir, constructed in the early 1960s by Cardiff Corporation to provide a source of clean drinking water for the rapidly growing city of Cardiff.

Now owned and cared for by Welsh Water we are a hub for health, wellbeing and recreation here for you to enjoy. The body of water that formed after building the dam created a haven for birds, wildlife, walkers and watersport enthusiasts alike.

A designated Site of Special Scientific Interest (SSSI) in recognition of its value to over-wintering wildfowl our watersports season runs from 1st March to 31st October.

Not For Profit

Welsh Water is a not-for-profit water company. We don’t have shareholders, which means that we put every single penny we make straight back into keeping bills down and looking after your water and beautiful environment – now, and for years to come.

We think it’s a much better way of doing things.
