The dwarf forest ( also called the cloud or elfin forest) lies at the very top of the mountain peaks along the ridges and receives, not only the most rain, but also the most wind. The soil is very thin due to constant rainfall erosion and the roots of the plants must spread out in a matrix over the ground, rather than grow down into a soil, which is not there.
The plants that do manage to survive these harsh conditions are different than the species of plants a little further down in elevation. Trees are stunted or 'dwarfed' due to the wind and a small tree in the dwarf forest can be very old.
Group tours do not access the dwarf forest because it is an additional 2 hour hike above Mt. Britton. Plan to hike up on your own, if you start early in the day. You should carry a rain jacket, it can get cold and wet. The little path to Mt. Britton does have some of the characteristics of the dwarf or cloud forest, so the 45 minute hike up to Mt. Britton from the parking does offer a glimpse of this uniquely dwarfed vegetation.
