Scattered around Iki Island, the new explorable area in Ghost of Tsushima Director's Cut, are animal sanctuaries where you'll meet some of the cuter inhabitants of Iki. Of the many sanctuaries you'll find, the toughest to reach is the monkey sanctuary at the top of Saruiwa mountain. But in addition to the sanctuary and the charm you'll earn from reaching it, the mountain also hides another secret: a hidden Trophy called "Monkey See."
To unlock the Monkey See Trophy, you have to find some specific locations on Saruiwa and take some specific actions. Here's everything you need to do to unlock the Monkey See Trophy.
The trick to the Trophy is to seek out each of those three trophies around the mountain. They're actually pretty easy to find, however.
The second monkey statue is off the path to the right, where you can climb down. Throw a smoke bomb in front of it to activate it.2. Mizaru, See No Evil: Return to where you climbed up and go through the narrow passage. That'll put you on a mountain path that continues upward. Wait for a break in the rock wall on your right. You'll see both a footpath ahead and a spot where you can climb down on the right. Take the climbing path down--be careful, as the first handhold will break away when you grab it--and descend to the bottom. There, you'll find the statue in a small alcove, next to a painting of a samurai with lightning bolts behind him. This monkey is all about being blind, which is your clue to how to trigger it: stand in front of it and throw a smoke grenade to make yourself disappear.
The last monkey can be reached when you cross a bamboo footbridge to find a path you can climb down using your grappling hook. Descend to a small pond below and swim across it to find the last statue. Bow before it to activate it.3. Iwazaru, Speak No Evil: The last monkey is a little farther up the mountain. Return to the footpath and keep going until you cross a bamboo bridge. You'll eventually see a slackline that lets you cross to go further, and if you're paying attention, a climbing path on your left leading up. Ignore the upward path--you actually want to climb down a significant way to reach the last monkey. Keep following the footpath until you can start using your grappling hook to climb downward. Descend until you find a tide pool with monkeys all around it; jump in and swim to the other side, where you'll find the last monkey statue covering his mouth. Since this monkey doesn't speak, you need to communicate with it non-verbally, so to trigger it, stand in front of it and bow.
If you've done it all correctly, you should get small cutscenes from each statue. When you're done, climb back up to the slackline above the pond where you started and take the handholds to climb up.
