This page provides detailed information on how to unlock "Your Prize" bronze trophy in "Uncharted: The Lost Legacy". This trophy is awarded for reaching the scenic point in the Hoysala Empire.
You can obtain this trophy in the fourth chapter of the game (Western Ghats), i.e. the one that takes place on a large map and provides you with freedom of exploring. You have to reach the tall tower shown in the above screenshot in the central part of the map. Start climbing up the tower, where you have to grab ledges and use the grapple.
After you get to the top of the tower, open all the doors which, by default, are for revealing all the key locations on the map. In this case, however, you do that to find out where to continue climbing. This has been shown in the above screenshot.
Keep climbing, because you have to reach the top of the tower (screenshot 1). After you get there, do not move for several tens of seconds. Allow Chloe to say all of her lines and to start her yoga practice shown in screenshot 2). This is when the trophy is unlocked.
