One of the gems in Cornwall’s horticultural heritage, Trebah Gardens slope down to the north banks of the Helford river. There are huge gunnera tunnels to be enjoyed at this time of year (June) and tumbling streams and tranquil ponds. You can also access the private beach on the riverbank. There are rhododendrons, magnolias and clouds of hydrangeas. There is also a cafe and shops filled with some really wonderful locally produced crafts, foods, and things for the garden. Dogs are welcome throughout the garden on leads.
