Hidden Valley

 is located in what is apparently an abandoned military establishment, there exists 4 bunkers riddled with anti-war graffiti. The area is nestled between hills and rocks, the main access being via a road near Goodsprings. Additionally, there are small side-paths, at least one of which heavily inhabited by bark scorpions.

Upon entering each bunker, the player sees an empty room with a locked door and intercom on the opposite side. The locked doors are of varying difficulty. The Easy door is confirmed to have nothing but rubble behind it. In one bunker, however, there is also a journal sitting on a crate, along with a sack with some fruit and other edibles in it. It reads, "This location looks like it might make a good safehouse. Warm, dry, and some sort of crazy natural phenomenon at night should keep the predators away. I'd love to start getting set up, but there are a few nearby points of interest I need to gather intel on first. Not sure how long that'll take."

During the night, vicious sand storms rage, making it quite difficult to see.

In what is apparently an abandoned military establishment, there exists 4 bunkers riddled with anti-war graffiti. The area is nestled between hills and rocks, the main access being via a road.Additionally, there are small side-paths at least one of which heavily inhabited by bugs.

Upon entering each bunker, the player sees an empty room with a locked door and intercom on the opposite side. The locked doors are of varying difficulty. The easy door is confirmed to have nothing behind it. The Average one contains rubble. In one there is also a journal sitting on crate,along with some fruit and other edibles in it.

This is also the location where you will meet the Brotherhood of Steel. They maintain a bunker.

Note: If you have discovered the two dead Brotherhood of Steel Paladins at the REPCONN facility (on the third floor) and took the note they were carrying, you can say the password to the intercom of the facility with the Very Hard lock. You can also gain access through the quest Wild Card: Side Bets.

There are two very hard locked doors in two of the bunkers. Behind one is also rubble. Behind the other one in the entrance to the Brotherhood of Steel bunker, where an explosive collar is placed upon the courier's neck.
