Even on an electric mountain bike in turbo mode, some sections are impassable. To get through them more or less, you have to look for the sides of the track, where a bit of grass allows you to pass without getting stuck in the sand.

The sandy trails are impassable by bike. We had to walk a lot on these trails.
