The 60-day ArcGIS Desktop Advanced free trial ended in 2020. Esri now focuses on ArcGIS Pro, which offers a 21-day trial designed to help users evaluate modern GIS workflows, including many of the same spatial extensions once bundled with the older Desktop Advanced trial.
Esri provides a free trial for ArcGIS Pro, allowing users to explore the latest desktop GIS environment. The trial is useful for testing workflows such as raster analysis, terrain modeling, site suitability studies, and enterprise GIS data preparation.

During the trial, you can evaluate ArcGIS Pro’s integration with ArcGIS Online, its support for GeoPackage, and its advanced geoprocessing capabilities. This is especially valuable for forestry and land management professionals who need to test map production, lidar processing, or spatial modeling before committing to a subscription.
Previously, a 60-day trial was available for ArcGIS Desktop Advanced, which included ArcGIS 10.1 for Desktop and several extensions. That older program was useful for learning desktop GIS and exploring tools such as advanced spatial analysis and network modeling.
For the latest trial details, always check Esri’s official website. If you are evaluating software for GIS projects, compare the current ArcGIS Pro trial with alternatives such as QGIS and open-source spatial tools to choose the best solution for your workflow.
