No need to get high tech and go fishing on Strava when the trails can be plainly seen from a distance, let alone the parked cars....or Google Maps/Earth.
Not always!!! sometimes Google can lag behind 2 -3 years depending on last sat shot.
New trails don't always mean new parking area.
If there's any decent vegetation you wouldn't be able to see a trail very well, if it is constructed right.( here in our wide open deserts, that ones a lil hard) but you can build through/over rock to hide lines in and out.
