Tolmer Falls, Waterfall in Litchfield National Park, Northern Territory, Australia

Tolmer Falls is a two-tiered waterfall in Litchfield National Park that plunges about 42 meters from sandstone cliffs into a deep gorge. Water flows over a natural stone bridge, creating a dramatic cascade within this section of the park.

The waterfall was named after Alexander Tolmer, who worked with Frederick Henry Litchfield in the South Australian Police force. This naming choice honors the historical connection between the two men and their time in service.

The falls were named by explorer Frederick Henry Litchfield after Alexander Tolmer, a colleague of his father in the South Australia Police. The gorge below is noted for a colony of orange leaf-bats (Rhinonicteris aurantia) numbering in the thousands, which roost in the surrounding caves.

Visitors reach the waterfall via an 800-meter return walk from the parking area to a designated lookout platform, typically taking 15 to 20 minutes. The path is relatively flat and well-marked, suitable for people of varying fitness levels.

Nearby caves shelter colonies of orange leaf-nosed bats and ghost bats, species that are rarely found in other locations. These creatures are an important part of the local ecosystem and draw researchers and nature enthusiasts interested in bat conservation.
