Loon lake is a awesom area. There is a ton of places to go and miles and miles of road to explore.. some nice little lakes around there too.
If you stay on loonlake road and go untill you hit gravel you will come to a cattle gaurd that is the beginning to the baker ranch. Go throught the ranch but stay on the road untill you come to the next cattle gaurd that is where your out of that part of the ranch. take the right at the fork in the road and that will take you to heyum lake. I would get a map book for that area because there is a ton of roads araund that area.
Not to much for hard wheeling pretty much just dirt road, Either way your going to have fun up there!
