Hidden Valley is a military installation nestled between hills and rocks roughly northeast of the New California Republic Correctional Facility and southeast of Sloan. The valley is home to numerous bark scorpions and the remnants of the Mojave chapter of the Brotherhood of Steel that once occupied Helios One.
To the eyes of the average wastelander, Hidden Valley is nothing more than a fenced-in plot of land with underground bunkers dotting the area. It seems that nothing of value is in the area, except maybe for bark scorpions and their venom. However, the truth is quite the opposite.
The installation was established as part of the Hidden Valley project, as a self-sustaining shelter for high-ranking VIPs, in order to provide a command and control facility in times of crisis. The actual installation is located several hundred feet below the surface, under multiple layers of reinforced materials connected to the northernmost bunker via a high speed elevator. The volume of earth and armor renders it impregnable to destruction, save for a direct hit by a bunker-buster nuclear weapon of tonnage considered outside of America's closest competitors before the war. Additional protection comes from the Dervish camouflage system, which generates an artificial sandstorm using sand supplemented by a combination of aluminum and various silicates, dispersed by a widespread network of industrial fans to blanket the area in chaff. Coupled with Black Mountain's electronic countermeasures, the site is effectively impossible to target or track with electronics.
The installation itself is powered by a specially designed Candle fusion power system, designed for reliability and duration of service, able to supply the power for an estimated 752 years (at least until year ~2700).
Other facilities include living quarters (both large dormitories and individual rooms), an infirmary equipped with surgery equipment, storage space, workshop, research laboratory, command center and more. For these reasons Hidden Valley was occupied by Brotherhood of Steel and adapted as the regional headquarters for the new Mojave chapter. Judicious use of the Dervish system, not to mention adherence to strict covert operations protocols allowed the bunker to remain hidden from NCR forces. This proved invaluable following the defeat at Helios One in 2276, when the remnants of the chapter retreated to Hidden Valley and hunkered down. The freshly promoted Elder Nolan McNamara ordered a lockdown, prohibiting personnel from leaving or entering the bunker, to maintain secrecy. Only supply runs and top priority combat missions were allowed to come and go.
This state of affairs continued for several years. Extended isolation strained the morale of Brotherhood members forced to idly sit underground and go through combat drills (both real and virtual) endlessly. Dissent began to take root, particularly in Head Paladin Edgar Hardin, a combat veteran of the Brotherhood war, who considered this inaction as crippling to the order. This was not the only issue that worried Elder McNamara: the bunker's system have been slowly deteriorating due to an overuse of the Dervish system and eventually would threaten the Brotherhood's survival.
The Courier entered the scene in 2281 and can play a pivotal role, either restoring the Brotherhood's presence in the region or destroying it outright.
Hidden Valley can be accessed via the road near Sloan and at the northwest and southeast corners where the fence is down. There are also small side-paths, at least one of which is heavily inhabited by bark scorpions and the occasional giant radscorpion when going in the direction of Scorpion Gulch nearby.
Inside the fenced area, four bunkers are spread around the perimeter of the area. Three of four bunkers are just a large entry room with a locked door on the opposite side that lead to nowhere, but may contain some notable loot.
 East bunker
The entry room has two skeletons with a bottle of wine on a sleeping mat and a suitcase, which would suggest a sad story. The locked (easy) door in this bunker hides a hundred 5mm rounds and twenty four 5.56mm rounds.
 North bunker
 South bunker
This bunker has two grenade bouquets hanging from the ceiling at the bottom of the staircase. The entry room contains a sleeping pad and a sack, along with a journal indicating that someone is using the bunker as a safehouse. The locked (hard) door here opens the way to 3 ammunition boxes, a mini nuke under a tin plate which you will have to move in order to see, a steam gauge assembly and two units of scrap metal on the right, and frag grenades and some 5.56 ammunition on the left.
 West bunker
The fourth bunker, also known as Hidden Valley bunker, is the home of the Brotherhood of Steel. The bunker is marked by a small broken tree stump directly on top of the dome. You will not be able to gain access to this bunker unless you have taken the holotape containing the passphrase from the two dead Brotherhood of Steel Paladins at the REPCONN Headquarters, the one near Black Mountain, or the 2 dead Brotherhood soldiers in a ditch on the artillery battered area outside Nellis Air Force Base.
If you have the holotape and passphrase, the player will be given the option to say it into the intercom. Otherwise you can attempt to pick the Very Hard lock or by having follower Veronica Santangelo with you. Access can also be granted through the quest Wild Card: Side Bets or by advancing far enough in any storyline to be asked to interact with the BoS.
 Notable loot
- The north bunker contains a pair of mini nukes, a stimpak and some 5.56mm ammunition.
- The south bunker contains another a mini nuke under a tin plate.
- A hollowed-out rock with a heart and anti-bomb symbol painted on it will contain some random loot. When you fast travel to Hidden Valley, the hollowed-out rock will be in front of you.

 Unmarked quests
- The south bunker will be empty when entered unless the Still in the Dark quest has been activated, which will cause the NCR Ranger to appear within near the campfire.
- Going into the Brotherhood of Steel bunker wearing any type of NCR armor will automatically make the entire bunker hostile. Even if you enter with Veronica as your companion, you will be attacked if you are wearing NCR faction armor.
- If entering the Brotherhood secure area using the passphrase, you will immediately start the NCR Ranger portion of the Still in the Dark quest. Your weapons and armor will be taken, but will be given back once you have completed this task. See Still in the Dark for more information.
- If you pick the lock, the Brotherhood soldiers will not be hostile, but when you leave the bunker again your followers will be locked in the bunker; meaning you have to unlock the very hard door again to get them back or get them after you complete the Still in the Dark quest.
- If you detonate the self destruct sequence, the Dervish camouflage system is disabled and smoke rises up out of the air shaft vents scattered around the bunkers.
- The interior of the Brotherhood's bunker looks very similar to Raven Rock from Fallout 3.
- Four Brotherhood of Steel paladins will regularly go out on patrol between 1AM and 3AM, guarding the area near their bunker until just before dawn.
Hidden Valley appears only in Fallout: New Vegas.

- Originally, the player was supposed to be able to spy on Taggart for Schuler and discover a PTSD (Post-Traumatic Stress Disorder) virtual simulation, according to the following script attached to VDialogueHiddenValleyLindaSchulerTopic009 (I don't appreciate how much harder I have to work to cover for his tendency to focus on his personal projects. I try not to think too much about his personal proclivities.:

- It was planned for the player to be able to use the VR pods here, probably to play a VR simulation where the player must defend Hidden Valley from Enclave intruders. There is a VR pod called HVPlayerPodREF and a message called HVGameScoreMessage that tracks a variable to display the number of kills in the VR game. There are also cut notes relating to Melissa Watkins that show she is playing the VR sim at a deliberately lower difficulty level. There is also an unused computer terminal called HVPodSimSelectionTerminal that seems to relate to the above.
- There are unused AI packages for NPCs of both sexes to use the relevant bathrooms here.

- bark scorpions right outside of the bunker you came from. In the later patches, bark scorpions spawn less frequently. After wandering though the bunker and exiting out into the wasteland again sometimes might spawn around two to five
- Sometimes the BOS will become hostile without apparent reason.
- If you fast travel to Hidden Valley and arrive just before the sun rises, the ground may turn black and the distant surrounding areas will have turned into a hazed green. The ground will eventually change back into color but the screen will go completely black afterwards and the game will need to be restarted. A way to avoid this is if you make your way out of Hidden Valley before the screen changes. This is most likely a glitch from the sandstorm that flows throughout the area at night.
A Securitron mk1 may spawn in the bunker, blocking the player.
- This may also occur if the player uses the wait function while in Hidden Valley.
- ED-E My Love, traveling to Hidden Valley in any way will cause the game will crash, making the quest to upgrade ED-E using the Brotherhood of Steel impossible. Sometimes after starting
- In the south bunker, if you activate the tripwire (which is attached to the grenades), it may kill you and freeze the game/console.
- It is possible to go through the ruins blocking the entrance to the bunker. You are unable to get out however once inside.
- Hidden Valley bunker terminal entries: "Project Goals: Hidden Valley
The goal of the Hidden Valley project is to create a self-sustaining shelter for high-ranking VIPs that can serve as a command structure in times of crisis. The bunker itself is located several hundred feet below the surface. Multiple layers of reinforced materials serve to prevent a breach of the inhabitable areas by anything save for a direct hit by a bunker-busting weapon utilizing a megatonnage considered outside the capability of America's closest competitors. In the event that our enemies become capable of such an attack, the bunker's DERVISH camouflaging system makes targeting the site impossible for automated systems, forcing aggressors to rely on guesswork and sheer luck."
- Hidden Valley bunker terminal entries: "The DERVISH Camouflage system provides visual and electronic interference to prevent airborne or long-range enemy weapons from targeting the bunker. The normal soil around Hidden Valley has been supplemented with a combination of aluminum and various silicates, which are then dispersed using a widespread network of industrial fans to blanket the area in a cloud of what is essentially chaff. Combined with the electronic countermeasures of the nearby array at Black Mountain, the bunker at Hidden Valley is effectively impossible to target."
- Hidden Valley bunker terminal entries: "The CANDLE Fusion Power system provides power to all bunker systems. Built more for reliability and duration of service, the power output of the system has been exceeded by many current designs, but it can supply the bunker with power for an estimated 752 years."
- Robert House's dialogue: "Where do you want me to start?" (The Courier)
"Since 2278, I've lost five roaming Securitrons near Hidden Valley. I didn't receive any clear video of the incidents, but telemetry from the units destroyed indicates they were attacked with energy weapons. It's obvious that the Brotherhood has a base in Hidden Valley or thereabouts. Finding it won't be easy, but getting inside will be the real trick."
