The widest path out of the clearing she was in actually led to a river and a cliff. At the edge of the cliff, Beatrix was able to see the familiar shape of Truce and Guardia Castle in the distance.
THe path besides the cliff moved across the river and down several hills, and back over the river once more. Along the path had a bunch of other imps lingering around.
Of course, this isn't a game, so it's not like you're actually restricted by invisible walls.
