I'm a new user of the Garmin Etrex 35 GPS device and I'd like to use all or as many options as it offers. As a beginner, though, I ran into a problem on how to download GPS tracks to my device. In the track collection, they are all recorded in .plt format. Do I have to convert them to .gpx and only then copy to Garmin? And next question: which Garmin folder do they belong in?
Thanks to the experts for the explanation.

Thanks, @smetar and @rok. For starters that'll do, I'll learn more along the way

No snow on Trstelj.

From Kranjski Rak the road is plowed, but not salted. You can drive normally to the "quarry" with a car.
