NOTE: This walkthrough assumes you're going for the achievement/trophy "The End Doesn't Justify the Means," which involves keeping all the monks alive. If you don't care about this, you can obviously be less careful in combat situations.

Follow the tunnel to the steps in front of the monastery, where you'll see 2 cultists (1-2) fighting 3 monks (1-3). Try to kill the enemy with the ski mask and camo pants first so he doesn't harm the monks.

The monks should deal with the other guy.

Take 2 sets of Uzi clips (1-2) from one corpse and a small medi pack and automatic pistol clips (3-4) from the other.

The monastery doors are locked, but you can get in through a window. If you want the achievement/trophy "An Unexpected Visit," do not climb the ladder opposite the steps. Instead, go through the stone archway beyond.

Climb the jumble of rocks on the right and shoot a crow (3) that approaches from near the building.

Continue around the side of the building.

Climb the rocks to reach the ledge with the brown door.

This door is just decoration. Move to the right end of the ledge. Now you're going to take a carefully angled running jump around the corner to grab the stone ledge beyond.

To set it up, stand at the corner of the building at a roughly 45-degree angle to the edge of the ledge.

Hop back once. Sidestep once to the right.

Then pivot slightly to the left so Lara is once again facing just to the right of the corner.

Now take the running jump, pressing Left while Lara is in the air to veer in that direction...

...and grab the stone ledge just to the left of the horizontal crevice. Pull up.

Step up onto either windowsill to unlock the achievement/trophy.

Then shoot out the window and enter the monastery.
NOTE: If you take this route, rather than the ladder, you'll miss 2 enemies: a pair of crows (4-5). You can go back and kill them if you like. Details are on a separate page.
DARK MODE: I plan to add optional dark mode for these pages, but my current priority is updating the walkthroughs. Meanwhile, may I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's official add-on/extension site.)
