Welcome to Treborth Botanic Garden

The Grounds

Treborth Botanic Garden covers an area of 18 hectares on the shores of the Menai Strait and has been owned by Bangor University since 1960. The garden comprises 15ha of native woodland, 2ha of species rich unimproved grassland and 1ha managed orchard and many mature trees and shrubs.


There are also six glasshouses of varying temperatures, with special collections including orchids, cacti, succulents and carnivorous plants. The outside garden has free access to the public at all times and the glasshouses are open at selected times when staff or volunteers are present.

Friends of Treborth

The garden is fortunate to receive the support of a well organised charitable body – The Friends of Treborth Botanic Garden – who in addition to undertaking a variety of fundraising activities are active in assisting the garden staff in the maintenance and development of the external garden, woodland and glasshouses.


Volunteering at Treborth is a great way to learn more about plants and the natural environment. In fact, much of the garden is maintained by volunteer support and we're tremendously grateful for all the support we get. Find out how you could get involved ...
