If you trigger the boulder near secret #2 and hop back out of its way, you can still get into the secret area.
Face the wall on the right. Step forward so Lara's chest is against the wall and then sidestep to the left as far as you can.
Adjust Lara's angle by turning slightly to the right (as as indicated by the dashed line beneath her feet).
Then side flip repeatedly to the left toward the boulder. Eventually Lara will squeeze between the boulder and the wall...
...ending up in the corner behind the boulder.
Turn to face the wooden crate. Then side flip once more to the left.
If you have Action Indicators enabled in the Options menu, you'll see the hand icon.
Now you should be able to push the crate into the room behind it and access secret #2. Continue following the main walkthrough.
DARK MODE: Even with brightness adjusted, dark images on a light background can be hard to see. 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 web store.)
