Inside the GREEN CAVE is a well-lit opening overlooking the river. Go through to an open area were the water spills over a cliff into a small pool. Climb onto the tan rocks on the left.

Walk down the slope to the end of this rocky ledge.

Don't jump into the water just yet. There's some ammo on a small ledge on the far side of the pool and a secret inside the little cave below on the right.

Take a running jump across the gap to the next stone ledge and kill 3 more vultures.

Here it may help to jump across and trigger the appearance of the vultures and then roll...

...and take another running jump back to the ledge you came from.

This wide ledge gives you more room to maneuver as you shoot the birds. When the coast is clear, jump back across the gap to the rectangular ledge that runs along the left canyon wall and move to the far end of it.

Jump from here to the small square ledge ahead on the right. Safety drop to the ledge below and pick up harpoons and MP5 clips.

Turn around and take a running jump across the pool to grab the horizontal crevice. Traverse to the right, pull up, and crawl into the cave.

This is SECRET #5. Get the goodies—a save/power-up crystal, harpoons and shotgun shells—then back out and drop into the pool.

NOTE: This will be secret #4 if you took the PATH THROUGH THE RUINS, as described in the main walkthrough.

This is SECRET #5. Get the goodies—a save/power-up crystal, harpoons and shotgun shells —then back out and drop into the pool.

Notice the broken raft in the pool below the falls. Apparently Tony came this way as well. Swim down and grab the small medi pack sitting on the bottom near the raft. Then climb out of the pool and follow the rocky passage behind the waterfall to finish the level.
