So i stumbled upon this castle that has some sort of treasure in it. I went all the way around and cant find a way to get in. Here are some screenshots detailing the location and look
A Witcher 3 question; haven't seen one in like forever and a half. I loved every minute of this game. Man, it's been so long since I've played :-(...p.s. I had trouble with this castle as well :-)– MonkeyZeusMay 2, 2016 at 21:19
It turns out there is a secret underwater entrance near the place of power. But you need to dive there for it to appear on the map
3You will see a lot of Drowners hangs there so prepare your crossbow .-)– PeterCoMay 2, 2016 at 11:53
1I cleared it already. I'm way over leveled for this. Turns out its part of the Griffin scavenger hunt that I never had interest of doing. May 2, 2016 at 11:54
In addition to the underwater entrance near the place of power, I've found that a running leap can land you on the structure at the "hinge" of the drawbridge. To the right of the drawbridge among the bushes is a crumbled wall short enough for Geralt to do his legs-to-the side vault over.
I was able to 'climb' up the side of the rock where the castle is standing on and jump my way into the fortress. Didn't even know you could swim in until I was already inside.
