Puzzle #1: You will come to a part with a big crane, the only puzzle in this tomb.
Along the way you must also rappel down some walls to swing to platforms below. It’s basic traversal you already know but if you get stuck, take a peek at the video guide. You must climb a tree and jump from the tree branch. Solution: As with all challenge tombs there are some climbing sections at the start of the tomb.
The entrance is just in front of the “Jungle Ruins” base camp.
