Once across the new bridge, head to the left. Have Ico climb the chain and then follow the wooden path to the right. Turn left where it crosses and push the block off the end. Have Ico retrace his steps back off the wooden path, then continue on to the ladder and climb down. Walk over toward the closed Idol Doors and push the block against the wall below the wooden structures. Climb up, then walk to the left and pull the switch on the wall, which causes the chain that's suspended from the right wooden structure to be moved out between the end of the wooden cross pathway and the structure supporting the turnstile, which Ico needs to get onto. Have him drop back down on the box and then onto the floor. Then head back to the ladder and climb it. Walk back out onto the wooden cross structure toward the hanging chain past the end. Have him run and jump onto the chain. Note the wooden structure directly behind him. Have Ico drop down the chain until his hands are about even with the last horizontal bar in the wooden structure and facing the turnstile. Get him swinging really well (it'll take five or more swings), then have him jump at the end of an arc and he'll catch the edge of the structure that supports the turnstile. Have him get on top and go to the turnstile and push it counter-clockwise two full revolutions to release a large block, which swings out into position.

Now, jump back onto the chain. Position Ico at the same elevation on the chain as he was when he leapt off in the opposite direction and facing the wooden platform. Get a good swing going again, then jump to the wooden platform at the end of an arc closest to it. Walk out onto the arm of the cross that points back toward where this area was originally entered from. Have Ico walk to the end, hang, and drop to the floor below to rejoin Yorda. Have Ico jump onto the suspended box, then jump back as Yorda is being or soon will be attacked by a couple of shadow demons and the portal is near the chain up to the wooden cross pathway. Dispatch them quickly, then have him jump back onto the box and call Yorda over. He should next jump onto the ledge with the Idol Doors and again call and help Yorda over. Have Yorda open the Idol Doors and then pass on through them into the upper level of the Graveyard area.
