Path to the hidden teleporter to Mohgwyn Palace in Consecrated Snowfield (see descrip. for details)
For the people who, for some reason, decided to kill the NPC, White-faced Varre, and then realized that they blew their chance at using the best farming spot in the game, now you can get there, although it's much later in the game.
I started at the Inner Consecrated Snowfield site of grace, which is very close to where you grab the map fragment (it's directly south from there).
From the site of grace, you are going to head directly west to the western edge of the map. You will be invaded twice along this path. Once, in the area I pass at the 0:45 timestamp and then again in area at the 1:00 mark, by the dogs. Try to lure the invader away from the dogs. The invader's weapon can quickly build blood loss and dogs can, too, making it a difficult encounter. Then continue on to the teleporter. Once tekeportrd, simply make your way down to the site of grace below. This is the classic farming spot: you can farm the giant bird patrolling the lake below or the sleeping (?) Albinaurics on the slope that leads down to the lake.
