The Darwin City Geotrail evolved over a period of 4 years shortly after the authors return to his hometown, Darwin.   A 16-year journey and experiences through Alice Springs, Roxby Downs, and Adelaide and through multiple industries has influenced the formation of the Geotrail with many familiar places seen through a new lens, and appreciation of things previously hidden in ignorance.

Darwin city hosts some interesting geological features, with some stories are literally written in stone.  However, there is more to the history and evolution of Darwin than the landscape. The Darwin City Geotrail is about telling some of those stories.

The journey into Geoheritage and Geotourism can be enriching and rewarding and Darwin has an interesting story to tell, extending back over 1.8 billion years.  It is a story that many non-geoscientists are not aware of, yet it captures their attention and interest when stated.

The Darwin City Geotrail (DCG) was launched in August 2020, within the resourcing and time constraints of its author.  Several ambitious components were descoped from the launch due to these constraints but remain firmly on the enhancements pipeline.

The DCG has already triggered a few alternative responses – positive, neutral, and negative.  Some were anticipated but many others have launched new endeavours and rethinking of some aspects of the Geotrail.

Discussion will include the technical aspects on the Darwin City Geotrail, the issues and concerns encountered, and next steps in enhancing the Geotrail for future users.
