If you're using Anaconda3, the easiest way to install GDAL is to create a virtual environment through Anaconda Navigator, choosing Python 3.6 as the preferred version. Then, choose gdal from the list of uninstalled Python packages. This will install gdal version 2.1.0.
After installation, you can check if everything works OK by entering a Python shell and typing:
>> import gdal>> import ogr
You can check GDAL's version number as follows:
>> gdal.VersionInfo() # returns '2010300'
This means you're running GDAL version 2.1.3.
