Litchfield National Park, 120kms south west from Darwin, is one of the prettiest National Parks I have witnessed. It features numerous waterfalls which cascade over the sandstone ridge which is Tabletop Range.
Magnetic termite mounds, cool shady monsoon forest walks are a relief from the heat.
The best time to visit is during the wet season, although be careful of flooded roads and at the start of the dry season. We were a little later than the start of the dry and the waterfalls were not as spectacular as I would have wished for.
There are numerous tours leaving Darwin that will visit Litchfield National Park, however, we flew into Darwin and spent four nights relaxing in our resort and then hired a small SUV and with the help of a few tourists brochures and maps, we made our way through the park. We stayed a couple of nights at the Litchfield Tourist Park, which enabled us to relax in the evenings.
