Here you can learn how to get to the tower in Western Ghats in Uncharted: Lost Legacy. The tower may be explored in chapter four of the game, but it's an optional activity. Getting to the top will allow Chloe to mark the most important locations on her map. You can skip this activity - the map is available in the previous section of our guide.
The tower is located in the center of the map, north from the starting point. It's marked on Chloe's map from the very beginning - you can look at it often in order to make sure you're heading in the right direction. There are small ruins around the perimeter, but there should be no enemies.
After reaching the tower, exit the car and walk around the building. You can start climbing in the spot shown above.
During your climb to the top, you will have to use the grapple hook a couple of times. Each time you do that, you need to swing a little bit and jump towards a stone ledge. Your destination is the round room with numerous doors. You can go through them to discover the important locations around the area (the three forts, the Halebid gate and the ruins with the token map - all of them will be marked on the map).
After you explore the tower, interact with the central mechanism, which turns out to be a lift. This will take you to the ground floor.
