Shipwreck Beach - Returning from the Endurance Wreck

When you emerge from the tunnel on your way back from the Cliffside Bunker, the zip line you created to get here earlier is gone. You'll need to return to the beach another way. Use a rope arrow and the rope ascender to open the reinforced door on the left.

Go through, raid the food cache and then ride the zip line up to the high plateau to the northwest.

As Lara approaches, she hears 3 enemies talking. Drop off the line and take cover behind the boulder before they notice you. There's no real need for stealth here, since it's just a few guys, but it is possible to kill the nearest man using a headshot without alerting the others. Then finish off the rest.

Loot the first guy's body and, if you like, take a little rest at The Grotto Day Camp. Move to the wooden ledge near the rock where you just hid...

...and drop down onto the ledge below.

Then move up the path to find a GPS cache (13/15).

NOTE: If you missed the 8th GPS Cache earlier, the one sitting on the pier on the beach below (circled on the map in this screenshot), you can take a little detour now to obtain it. Or, you can continue with the story for now and return for the GPS cache later. Both paths are described in the notes at the end of the main walkthrough.

To rejoin Lara's friends and continue with the story, from the spot where you just found the 13th GPS cache, return along the path to where you just dropped down from above. Go through the opening in the rocks and around to the right

Jump to grab the ledge near the little waterfall, pull up, crack open the salvage crate. and then scramble up the painted wall to get back to the campsite.

Then scramble up the painted wall to get back to the campsite.

Move around to the gap near the waterfall and jump across to the area where the last 2 bad guys fell. Loot their corpses.

Then then jump to grab the zip line. There's no need to touch the controls as you ride the series of lines all the way down to the beach near the Survivors' Camp.
