Usually yes but one exception is very rugged mountains with steep valleys like the coast range in north Vancouver or big sur. You'll end up trapped.

That's a great point. I was working on the assumption that you had a map and a compass. When you get to dangerous terrain, hopefully you can pin down that you're on one of two or three possible spots - so maybe you can figure out where you are.

Regardless, yeah, wandering off in the woods unprepared is dangerous. and it's easy to get hurt and have worse things happen.
