You'll find the first Photo Opportunity spot for this level right at the beginning. Just turn the camera and you should see it no problem. Once you've snapped a shot, hop down to your right and hang on the ledge that's closest to the tree bridge below. Leap toward it only to have it collapse before Chloe can do much of anything, so now you'll need to find another way up.
Slide down the muddy path to the left then toss your grappling hook at the conveniently placed pole up ahead. Now climb up the rope so yo can run on the rock wall and leap to the handholds on the left. Climb on up from here to join Nadine.
Hop into the jeep and drive until you see the raging water ahead. Power through up the small hill and follow this stream. Stick to the left then stop once you're close to the edge. Do not drive off the edge yet.
This is the second Photo Opportunity spot for the level. Snap a photo of the flamingos then take the jeep down into the water below.
Treasure #1: Gupta Empire Coins
Once you've dropped the jeep into the water where the flamingos are, look ahead to see a big rock that looks like a ramp. This collectible is in the water behind that rock.
Moving on, drive through the passage beneath the waterfalls and keep going until you reach a gate. Watch the scene here before grabbing the winch in front of the jeep to wind it around the beam.
Treasure #2: Silver Water Jar
Fight off the ambush and climb up the structure the enemies were on. One of the bad guys would have dropped grenades, so grab some to throw it at the nearby wall. You'll find this collectible hidden behind said wall.
Now put the jeep in reverse and pull the door down to continue. Drive until you get to another stream.
Treasure #3: Golden Fish Statuette
After pulling the door apart with the winch, drive to the next stream and follow it as it winds to the left. Stop once you see the two waterfalls to your right. This treasure is inside the hidden passage between the pair of waterfalls.
From here, drive along the only path you can take and use the rocks to gain traction as you power through up the mud hill. You'll soon reach the temple where Asav's men are gathered.
There's a Photo Opportunity spot here but it won't appear while enemies are present, so clear the area first then stand on spot shown in the image above.
Lockbox #1: Silenced Pistol
This is found on the back of a truck outsid the temple. Pick the lock open to collect a golden Silenced Pistol inside.
Once you have everything, climb up the wall of the temple and pull the lever to open the door so Nadine can drive the jeep through.
Treasure #4: Mango Crystal Scent Flask
After you open the gate to the temple. Jump to and climb down the wall ahead. Do not drive off once you drop into the jeep. Instead look to your right to spot this collectible.
Drive up the hill and the next location should be at the other side which marks the end of the chapter.
