The garden contains a collection of giant Gunnera manicata, often referred to as 'dinosaur food,' which thrive in the sheltered valley floor.
During World War II, the beach at the bottom of the garden was used to launch over 7,500 men and 400 vehicles for the D-Day invasion of Omaha Beach.
The garden holds several 'Champion Trees,' which are officially recognized as the largest or tallest examples of their species in the UK.
The site utilizes a natural spring-fed water system that cascades through the valley ponds.
A significant portion of the garden's layout was designed to provide year-round interest through an architectural approach to foliage rather than just floral displays.
The garden was essentially reclaimed from a state of complete dereliction after being purchased by Tony and Eira Hibbert in 1981.
Trebah Garden is a 26-acre subtropical valley garden in Cornwall that descends directly to the Helford River. The site features a 100-foot-deep ravine created by geological shifts, providing a microclimate for exotic plants including giant gunnera and tree ferns. It maintains a private, shingle beach accessible only via the garden paths. The landscape was historically developed as an 18th-century estate garden with significant structural planting. It served as a pivotal embarkation point for the 29th US Infantry Division during the D-Day landings in 1944. The garden is managed by the Trebah Garden Trust, a charitable organization focused on conservation. Visitors navigate a series of winding paths that transition from woodland canopy to coastal flora. It contains a collection of champion trees and hydrangeas notable for their size and variety. The site integrates water features, including a series of ponds and small streams fed by natural springs.

Wear sturdy footwear with good grip, as the valley floor involves steep inclines and occasionally slippery paths.
Check the tide charts before visiting if you intend to spend time on the private beach, as the shoreline is narrow at high tide.
Use the shuttle service if you have mobility issues, as the return journey up the valley is a significant climb.
Attempting to walk the entire perimeter in one go without stopping, as the vertical elevation change is physically demanding.
Open daily throughout the year, though specific garden sections may occasionally close for essential maintenance or private events.
Dogs must be kept on short leads at all times; do not pick flowers or disturb wildlife in the water features.
