>Do you give them an empty hexmap to fill out?
Yes, as stated in pretty much all first decade sources. Picrel.

>An abstracted map of key locations?
No.

>Nothing and let them figure it out?
Absolutely not. Hexes are player-facing. They know which hex they are in (barring getting lost) and what the terrain of that hex is, and they mark it on an empty hex map that they are provided with.
