Days Gone has 14 Ambush Camps needed for complete the Ambush Camp Hunter Questline and trophy. This guide shows all Ambush Camp Locations and also their Bunker Locations.

The goal in each Ambush Camp is to clear out all enemies in it. Then you are given a search area to find the hatch to an underground bunker. Below are instructions where to find each bunker in the camp. Clearing out the camps is best done in stealth. The Crossbow and melee takedowns are perfect for this. You can also throw rocks to distract the enemies and then do stealth takedowns.

Clearing out all Ambush Camps should be one of your first priorities. They clear the fog from the map and reveal other Collectibles in the area. You also get Crafting Recipes from them, which is needed to craft all types of Crossbow Bolts for trophy "Variety is the Spice of Life".

None of these are missable! After the story there's free-roam and you can go back to all regions and finish up any side activities and collectibles you have left. It's worth noting that there are two temporary points of no return. One at the end of 3rd region "Lost Lake" and one more at the end of 5th region "Crater Lake". This will lock you out of some regions until the end of the story. Then after the story the whole map opens up again.
