Navigating to a Point Which is on a Trail

As you probably know, you can select a destination by going to the Map view, finding the right location, then touching the spot to which you wish to navigate. Fairly reasonable, right?

But what if the point you select as your destination is on a trail---in other words, you've been there before or at least drove past it?

Creating a destination out of a point which is on a trail is still a mystery to me. When/if I figure it out, I'll let you know here.

Or perhaps you already know how! If you do, leave a comment, please!
