There are a total of sixty secrets to be found. When you climb a building that has a supply drop, the map will show some secrets. Others must be found. One particularly difficult one is found on top of the clock tower where you left your little brother.

There are eight landmarks, marked as small drawings on the map.

There are 26 boat boosts, found at the indicated locations.

Remember when looking for secrets and boat boosts to use your monocular to focus in on them. You can do this by pressing 'Triangle'.
