It is possible to reach Karlach very quickly - to the NE of Scratch one may jump over the stream (no need for bridge), turn right and get to her without any fights between Druid Grove Gate and her location.
BTW - in my first exploration I missed Astarion completely, never investigating that side of the Nautiloid.
BTW2 - Shadowheart is on the beach if we extracted her from the cocoon. Otherwise she is moping in DG.
