Trebah Garden is a coastal garden located near Mawnan Smith, south of Falmouth in Cornwall. It is a large, privately managed garden set within a sheltered valley that descends to the Helford River. The site is known for its subtropical planting, supported by the mild climate of the south coast, and is considered one of the more established garden attractions in the region.
The garden is arranged along a central valley, with a network of paths leading through woodland, planted borders and open lawns. The planting includes a wide range of exotic species, with seasonal variation throughout the year. At the lower end of the garden, paths lead to a private beach on the Helford River, providing a coastal element to the visit. The layout involves gradual descent through the garden, with some steeper sections on return.
Access is via local roads, with a dedicated on-site car park located near the entrance. Entry requires a ticket, and facilities include a café, shop and toilets. The garden is well signposted, with a choice of routes depending on time and mobility. While many paths are maintained, some sections involve slopes and uneven ground, which may affect ease of access for certain visitors.
The garden is open for most of the year, with spring and early summer offering the most varied planting displays. It is suitable for visitors interested in gardens, walking and coastal settings. The sheltered valley provides some protection from wind, although wet conditions can make paths slippery. It can be busy during peak holiday periods, but generally allows for a steady flow of visitors without congestion.
Nearby, the Helford River offers additional walking opportunities along its banks, while Glendurgan Garden, located close by, provides a similar but smaller garden setting. Falmouth, a short drive away, offers a wider range of facilities, attractions and coastal access. Beaches such as Swanpool and Maenporth are also within easy reach.
