The Gloucester Tree

Years old250
Girth7.3 m
SpeciesKarri

A prince helped drill the holes. Prince Henry, Duke of Gloucester, came through in the late 1940s and worked an auger into this karri's trunk himself, which is how the tree got both its name and part of its ladder. The ladder was the point. In 1947 the forestry service picked this karri as a fire lookout, one of eight raised across the south west between 1937 and 1952, and George Reynolds drove a spiral of steel pegs up the trunk. Jack Watson, a forester and Gallipoli veteran who later ran Kings Park, made the test climb and took six hours over it. The job at the top was to see smoke over the karri forest before it turned into something visible from the ground. It became the second tallest fire lookout tree in the world, behind the Dave Evans Bicentennial Tree a few kilometres away. It stood 61 metres until a trim took seven metres of rotting crown off. The climb closed in November 2023 on safety grounds and reopened on 1 July 2026, now stopping at a platform 37 metres up rather than the old 53. There is still no harness and the risk is still the climber's own. At the climbing zone the trunk measured 7.3 metres round on that first ascent in 1947. Its age is a floor without a ceiling: sources say at least 250 years, and nobody has counted the rings.

Gloucester National Park, Pemberton, Western Australia 6260You can recognise it by the spiral of steel pegs driven up its trunk to a climbing platform. It stands in Gloucester National Park near Pemberton, Western Australia.

Free to view; DPaW national park day-use entry fee applies for vehicle entry to Gloucester National Park. Open daylight hours. The climb itself (pegs spiralling the trunk) reopened 1 July 2026 after a 3-year safety closure, now restricted to a new 37m platform (was 53m) after the crown was trimmed 7m for rot; no harness provided, climb at own risk.

No public transport to the park; ~5 minute drive / 3km from Pemberton town, which itself is rural and has limited coach/bus service. Car is the practical way in.
