A Century-Old Landscape of Natural Beauty

Parc Cefn Onn is a Grade 2 listed historic park situated approximately four miles north of Cardiff city centre, nestled on the northern fringes of the city near Lisvane. The park’s origins date back around 100 years when Ernest Prosser, a railway director, designed the upper park area to take advantage of the gentle valley carved by the Nant Fawr stream. Its historic layout features tumbling streams, winding paths, and a diverse collection of native and exotic trees, creating an intimate and picturesque woodland setting.

Seasonal Splendour and Botanical Richness

Visitors to Parc Cefn Onn can enjoy spectacular seasonal displays, from carpets of spring bulbs and exotic camellias to vibrant rhododendrons and azaleas in late spring and early summer. In autumn, the park’s trees and shrubs transform into a kaleidoscope of rich colours, providing a stunning backdrop for tranquil walks. The park also contains ornamental gardens and a peaceful pond with a summerhouse, originally built to help alleviate tuberculosis symptoms of Prosser’s son.

Wildlife and Woodland Experience

The park’s streams, ponds, and woodlands create a rich habitat for wildlife, making it a haven for nature enthusiasts. The semi-natural oak and beech woodland area, Coed Transh yr Hebog, lies to the north near Caerphilly Mountain, offering a more wild and natural experience. Throughout the park, visitors can explore winding paths, discover diverse fungi, and enjoy the peaceful atmosphere that encourages wildlife observation and relaxation.

Family-Friendly Activities and Accessibility

Parc Cefn Onn is well-suited for families, featuring a large open field at the top where children can play freely and safely. The park offers a Wildlife Explorer Trail and a variety of activities designed to engage younger visitors. It is wheelchair accessible and provides two Trampers for hire to assist visitors with mobility challenges. The park’s free car park and open access from dawn until dusk make it an inviting destination for all.

Historic Features and Artistic Touches

The Dingle, the historic northern garden, showcases rare and exotic plants and includes early features such as the summerhouse and former swimming pool. At the park’s entrance, a mural artwork in the subway narrates the park’s story, adding a cultural dimension to the natural setting. These elements highlight the park’s blend of heritage, horticulture, and community engagement.

A Gateway to the Countryside

Beyond its boundaries, Parc Cefn Onn provides access to the extensive footpath network of Caerphilly Mountain, inviting visitors to extend their exploration into the surrounding countryside. This connection enhances the park’s appeal as a peaceful country park offering both intimate woodland experiences and broader outdoor adventures.
