The Remnants - Back to the Main Path from Treasure #7

Tomb Raider Underworld screenshot
To reach the other side of the ruins, starting from the ledge where you just found the reward, take a running jump to grab the handhold on the square column ahead and to the left. Climb around to the right so that the slender, round column is directly behind Lara, and then jump back to grab it. Climb all the way up the pole to perch on top of it.

Turn to face the line of square columns and the horizontal beam where you balanced before. Jump forward to perch on top of the broken column. Then jump forward again to grab the handhold on the nearest tall, square column. Traverse around to the right and pull up to stand on the horizontal beam. Turn left and jump straight up to grab the handhold above.

Climb around the column to the right. Jump to the next column, then the next. (This is where you ended up after doing the chimney jump earlier.)
