Hi there, are the tracks marked this good, that you are able to find the way easily? And is it ok to hike alone? Thx

Depends on which track you're talking about. Most of the smaller and lesser known ones are hardly marked at all. It's best to follow trails listed on maps available with official kiosks. You could also follow other people going about. You can get lost on unmarked trails.

Agreed. The 1st answer is the perfect answer.

I'd add it's best not to walk alone except in well- travelled areas.

I second this
