If you grab a helicopter and fly (or use the wingsuit or parachute) around the Insula Striate area, you can find quite a few of these on your own just by looking down, as each tomb is covered in a circular pattern of distinctive blue flowers.
After finding a tomb, simply walk up to the door on the side and press Triangle on the PS4 or Y on the Xbox One to “pay your respects.” If you pay your respects to the dead at all 23 ancient tomb locations you’ll both nab the appropriately titled Tomb Raider achievement and unlock a new weapon that will be available through rebel drops.
Below you can find the locations of every tomb, or if you are looking for guides to specific Just Cause 3 challenges be sure to head over here instead.
Ancient Tomb #1
Province: Costa Sud
Coordinates: N 40 – 46.453 E 5 – 46.689
This first tomb is located on the far eastern end of the island (and the northeastern tip of the province) on the top of a hill just to the south of a large, open bay.
Tomb 1
Ancient Tomb #2
Province: Prospere
Coordinates: N 40 44.602 E 5 40.034
Near the south-to-southwest corner of Prospere (almost all the way into the neighboring province to the south), this one is a little harder to land, as there’s not a ton of room. Be careful not to slide off the side if you are parachuting or landing a helicopter on the small hillside just to the side of the main road below.
Tomb 2
Ancient Tomb #3
Province: Val De Mar
Coordinates: N 40 46.793 E 5 40.778
This one has plenty of wide open space, so feel free to bring your helicopter down to the tomb located on the western side of the province in between the two large bodies of water.
Tomb 3
Ancient Tomb #4
Province: Val De Mar
Coordinates: N 40 47.105 E 5 41.191
Slightly to the northeast of the previous tomb, this one is just north of the third body of water in Val De Mar. The tomb is located on the edge of a cliff and is flanked by a heavily wooded area on all sides, so wingsuit or parachute is the way to go here – unless you want to land your chopper a good ways away and hike over.
Tomb 4
Ancient Tomb #5
Province: Litore Torto
Coordinates: N 40 50.463 E 5 45.111
The fifth tomb is in a really awkward position on a large sloping hill on the northwest end of Litore Torto, so a helicopter is really a no-go here.
Tomb 5
Ancient Tomb #6
Province: Litore Torto
Coordinates: N 40 46.911 E 5 45.680
Not far off from some ruins, this tomb is at the very southern-central end of Litore Torto, just before it switches over to Umbra province and is located slightly to the west of the road.
Tomb 6
Ancient Tomb #7
Province: Libeccio
Coordinates: N 40 46.370 E 5 36.948
In the northern-central area of Libeccio (straight up from the finger of water that juts into the province), this tomb is located on a plateau ringed by trees on all sides, making flight of any kind the best way to arrive.
Tomb 7
Ancient Tomb #8
Province: Libeccio
Coordinates: N 40 45.897 E 5 32.755
All the way on the far western side of Libeccio before hitting the ocean, this tomb is found on the top of a grassy hill overlooking the water.
Tomb 8
Ancient Tomb #9
Province: Libeccio
Coordinates: N 40 45.976 E 5 33.677
The ninth tomb is a little hidden because it’s underneath a canopy of trees in a mountainous area, so you’ll have to parachute down and find it on foot to the east of the previous tomb.
Tomb 9
Ancient Tomb #10
Province: Grande Pastura
Coordinates: N 40 50.677 E 5 41.788
While there are trees here making helicopter landing difficult, there’s a nice open field just to the side if you fly a little further past the coordinates in the north-central area of Grande Pastura (just north of the road). There’s still a ways to go to discover them all. But on the plus side, we’re now in the double digits of tomb raiding!
Tomb 10
Ancient Tomb #11
Province: Grande Pastura
Coordinates: N 40 51.536 E 5 44.608
On another hill looking out towards the water, this tomb is found at the very northeastern corner of Grande Pastura before the land meets the ocean. This one is distinctive for having both white and yellow flowers in addition to the typical blue.
Tomb 11
Ancient Tomb #12
Province: Grande Pastura
Coordinates: N 40 49.943 E 5 41.844
This province has more than its fair share of ancient tombs! Tomb #12 is found in the middle of Grande Pastura in a clearing surrounded by trees.
Tomb 12
Ancient Tomb #13
Province: Grande Pastura
Coordinates: N 40 49.652 E 5 43.932
On the side of a cliff just below some ruins, the 13th ancient tomb (and final one found in Grande Pastura) is located to the southeast of the previous tomb location.
Tomb 13
Ancient Tomb #14
Province: Maestrale
Coordinates: N 40 47.192 E 5 39.018
Again found on a cliff near some ruins, this one is hard to get at from below and is easier to approach from above using a parachute.
Tomb 14
Ancient Tomb #15
Province: Maestrale
Coordinates: N 40 47.132 E 5 38.056
This tomb is located near the southeastern quadrant of the province, just a bit to the west of the previous tomb.
Tomb 15
Ancient Tomb #16
Province: Maestrale
Coordinates: N 40 47.182 E 5 36.893
You should be able to see a large ruined structure partially covered by trees as you approach this tomb even further west from the previous Maestrale location.
Tomb 16
Ancient Tomb #17
Province: Maestrale
Coordinates: N 40 48.526 E 5 36.044
A gorgeous view awaits you when find this tomb in the north-central area of Maestrale, located to the south of the ocean.
Tomb 17
Ancient Tomb #18
Province: Maestrale
Coordinates: N 40 48.782 E 5 35.442
Located along the top of a rocky ridgeline, Just Cause 3’s 18th ancient tomb is to the northwest of the previous tomb.
Tomb 18
Ancient Tomb #19
Province: Maestrale
Coordinates: N 40 48.815 E 5 34.563
A little more difficult to locate than the others, this tomb is under heavy tree cover and can’t be seen from above. You can find this one by heading north of Maestrale’s lake and finding the wooded area just to the northeast of Rocca Blau’s province border.
Tomb 19
Ancient Tomb #20
Province: Maestrale
Coordinates: N 40 49.473 E 5 34.271
Looking out over of the ocean, ancient tomb #20 is found in the far north end of Maestrale province.
Tomb 20
Ancient Tomb #21
Province: Maestrale
Coordinates: N 40 49.070 E 5 33.095
Found on a ridge up above the road that is accessible with your grappling hook, this tomb is to the west of the previous tomb and to the southeast of the large docks on the map.
Tomb 21
Ancient Tomb #22
Province: Maestrale
Coordinates: N 40 47.718 E 5 35.088
Slightly hidden by tree cover, the 22nd ancient tomb is actually just off the dirt road near a small bridge to the south of Maestrale’s major lake and to the east of the Rocca Blau border.
Tomb 22
Ancient Tomb #23
Province: Maestrale
Coordinates: N 40 45.740 E 5 38.740
It’s been an epic and lengthy journey across Insula Striata, but we’re finally at the 23rd ancient tomb, netting you the Tomb Raider achievement! The final tomb is on a tree-covered ridgeline at the very south end of Maestrale and to the west of Prospere.
Tomb 23
