Unfortunately there is no direct route to crisp point from the east. From whitefish point travel west on wildcat road, to vermilion road, then south on maple block road, west on betsy river road to CR 500, north to CR 412. 412 east will take you there.
You can also cut across snowmobile trail #8 from maple block to 412, instead of Betsy river road/Cr500
Either way make sure you have provisions for the sand. Wildcat road is deep, but totally worth it
