Lisvane and Llanishen Reservoirs forms a vital part of the green and blue infrastructure of Cardiff. The mix of grassland, woodland, scrub and waterside habitats offers opportunities for all kinds of wildlife and nature. There are two Sites of Special Scientific Interest (SSSI) and much of the grassland and woodland outside of the SSSIs is designated as a Site of Importance for Nature Conservation (SINC). Dogs are permitted on the café balcony, car park and Grab & Go seating area only and are not permitted anywhere else on the site, including the paths. Natural Resources Wales has advised that the risk from dogs to the fungi is too great. Waxcaps are very sensitive to changes in habitat such as fluctuations in soil moisture, temperature and nitrate levels which can reduce the production of fruiting bodies. In particular, sudden changes to nitrate levels on the site – from dog urine specifically – can have a detrimental effect on the fungi. There is a fully accessible Visitor Centre with cafe, toilets, free wi-fi, room hire, equipment hire, changing rooms and other facilities include the boathouse, bird hide, education centre, nature trails and paths, bike parking/shelters and car parking.

Enjoy a pretty stroll through the woodland surrounding Llanishen Reservoir. Well-maintained dirt paths will lead you around the forest where there is a rope swing and stream to discover, a little something for the kids to enjoy too.

Roath Park is one of Cardiff's most loved parks, it was recently awarded the prestigious Green Flag award to recognise its high quality and its importance to Cardiff. In the centre of the park sits the wonderful Roath Lake, a peaceful place to walk around with sights of ducks, birds, and an impressive lighthouse stood in the water. There is a lovely little café and plenty of places to picnic, so take a seat and enjoy the view.

St Fagans National Museum of History (Welsh: Sain Ffagan: Amgueddfa Werin Cymru), commonly referred to as St Fagans after the village where it is located, is an open-air museum in Cardiff chronicling the historical lifestyle, culture, and architecture of the Welsh people. The museum is part of the wider network of Amgueddfa Cymru – National Museum Wales. It consists of more than forty re-erected buildings from various locations in Wales, and is set in the grounds of St Fagans Castle, a Grade I listed Elizabethan manor house. In 2011 Which? magazine named the museum the United Kingdom's favourite visitor attraction. A six-year, £30-million revamp was completed in 2018 and the museum was named the Art Fund Museum of the Year in 2019.

In 1960, a private bill sponsored by Liverpool City Council was brought before Parliament to develop a water reservoir in the Tryweryn Valley. The development would include the flooding of Capel Celyn. By obtaining authority via an Act of Parliament, Liverpool City Council would not require planning consent from the relevant Welsh local authorities and would also avoid a planning enquiry at Welsh level at which arguments against the proposal could be expressed. This, together with the fact that the village was one of the last Welsh-only speaking communities, ensured that the proposals became deeply controversial. Thirty-five out of thirty-six Welsh Members of Parliament (MPs) opposed the bill (the other did not vote), but in 1962 it was passed. The members of the community waged an eight-year effort, ultimately unsuccessful, to prevent the destruction of their homes. When the valley was flooded in 1965, the village and its buildings, including the post office, the school, and a chapel with cemetery, were all lost. Twelve houses and farms were submerged, and 48 people of the 67 who lived in the valley lost their homes.[2] In all, some 800 acres (3.2 km²; 320 ha) of land were submerged. A new reservoir, Llyn Celyn, was formed. Many of the stones from the original chapel were re-used in the construction of the new Memorial Chapel. The water in the reservoir is used to maintain the flow of the River Dee (Afon Dyfrdwy) so that water may be abstracted downstream,[3] and additionally to improve the quality of white-water sports on Afon Tryweryn.
